Low cost ML-50 moisture analyzer is ideal for many wastewater applications when you're on a tight budget.  This moisture balance provides a rapid and accurate method for moisture content and dry weight analysis of a wide range of products and materials. In research work, as well as in manufacturing and quality control applications it is essential to be able to determine moisture content simply and reliably. Take a closer look and see the all the specifications by scrolling down this web page.

A major issue with ALL A&D moisture balances is the disposable moisture pans are not the standard 4" diameter like all the competitor models such as Sartorius, Mettler, Ohaus and Adam Equipment. We offer 500 disposable 4" diameter pans for under $155. Since the AND Weighing moisture pan is a different size you'll be required to purchase only their AX-30 Sample Pans (100 ea) for $52.00. So, 500 A&D moisture pans will cost you $260 ($52 x 5) while Precision Weighing Balances can offer you 500 disposable moisture pans for most Sartorius, Mettler Toledo, Ohaus and Adam Equipment moisture balances for under $155. So although A&D offers a low initial price for their moisture balance the cost of operation could be much, much more expensive purchasing those expensive disposable moisture pans. We never recommend reusing any moisture pan. Every moisture analysis test should be performed on a new disposable moisture pan for accurate moisture content results.

Never heard of A&D? A&D is currently the world's third largest manufacturer of laboratory and industrial balances with 20% of the world market share. Established in 1977, A&D Company, Ltd. has grown from developing digital-to-analog converters for companies such as Nippon Telegraph & Telephone, to becoming a world class producer of advanced measuring equipment for medicine, science and industry. A&D established itself as a multinational corporation, with offices in the United States, Great Britain, Germany, Australia, Korea, Taiwan and Russia, and as a world leader in measurement equipment. The company's competitive edge is the direct result of its ability to leverage strong engineering and manufacturing capabilities, while incorporating highly accurate analog and digital technologies into broad product lines focused to provide customers with the greatest value.

High performance and quality is shown with a 5 year manufacturer warranty. Review the manufacturer warranty from other manufacturer's and you'll see their warranty is a lot less. Plus if you ever need repair A&D Weighing has two facilities in the USA located in Georgia and California for fast turn around.

The best selling point is AND Weighing fabulous product support. A&D Weighing has a dedicated product support line by calling 1-800-726-4940 6:00 am to 5:00 pm PST. Finally the A&D is simply to use and configure. The product manual is written for the average person to configure their scale verses having to spend $100's calling for scale company help you figure out how to use the weighing device.

The Vacuum Fluorescent Display allows the results to be clearly displayed even in areas with poor lighting.  The large keypads and intuitive embedded software makes the A&D ML-50 moisture balance a breeze to use walking you through the convenient test setup parameters.

Attention to the placement of handles make the unit safe to use minimizing burn related mishaps.

Add it all up and A&D is Clearly a Better Value over all the other moisture balances on the market today!

Sodium Tartrate Dihydrate
can be purchased optionally for verifying the performance the ML-50 moisture balance.  Sodium Tartrate Dihydrate is a chemical used in the industry as a standard since it contains 15.66% of a chemically uniform moisture.  However, depending on the state of the preservation of the material the moisture of 0.1% or less adheres to the surface of it.
Moisture Analyzer
Checking the performance of the moisture balance is simple.  Preheat the unit for about eight minutes at 160°C, then put about 5 grams of Sodium Tartrate Dihydrate in the moisture balance.  The moisture content rate of 15.50 - 16.00% is obtained in a typical measurement.

 A&D technology increases your productivity

  • Fast heat to 200°C in only 2 minutes
  • Uniform heating drastically improved by SRA technology
  • SRA filter stops contamination from spatter of the test sample
  • Removable SRA filter makes for easy cleaning
  • User replaceable Halogen lamp cuts cost and down time
  • GLP compliant format when printed results are required

A&D know-how gives superior analytical performance

  • Repeatability of 0.1% (S.D.) in moisture determination
  • 50 gram capacity by 5 mg readability
    (MX-50 readability to 1mg while MF-50 is 2mg)
  • Programmable Heating Mode Memory
  • Easy to read Vacuum Fluorescent Display
  • Standard RS232 port for connection to optional printer.
Moisture Content AnalyzerAll A&D moisture analyzers measure moisture thermogravimetrically.  Thermogravimetric moisture analysis is based on the principles of vaporization of water during the during process.  The moisture balances monitors the weight loss of a sample as the material is heated.  The sample weight prior to heating and after reaching a steady-state mass after drying determines the moisture content.  The halogen bulb produces the heating of the sample by infrared radiation.  The thermogravimetric method offers advantages over moisture determination using a chemical method such as Karl Fisher Titration.  Thermogravimetric moisture analysis is simple to perform and adaptable to many conditions verses Karl Fisher Titration can be subjective, and require the handling and disposal of solvents and potentially hazardous materials.

Moisture in FoodDownload the A&D User' Handbook.  it's loaded with information including measurement and performance Q&A, examples of data results & analysis, overview of Win CT moisture analysis software and more.  You'll learn about the principles of how the A&D moisture balance determines percent moisture implementing basically a wet - dry analysis.  Additional review of other available technologies for determining moisture such as the Karl Fischer method are covered.  Learn the benefits & disadvantages of several processes available to analyze moisture content.  Finally the user' handbook covers expected measurement results along with optimum temperature settings & drying times for a myriad of samples from dried dog food to peanut butter, calcium carbonate to aluminum oxide or yogurt to cheese.  After review this information you'll be a moisture guru.
Warning - Moisture balances should not be used on any volatile organic sample with flash points.  Even a MSDS rating of 1.  Samples with low flask points like Acetaldehyde -38°C or MEK -4°C should not be used with the A&D ML50 Moisture Balance and maybe you should look at Karl Fisher as an alternative.

Although you might presently perform analysis with an oven on these samples the ovens typically have ventilation and a much larger cavity than the typical moisture balance that operates on the principles of TGA.  In addition, with most moisture balances there is no ventilation so all the fumes remain inside the hood of the moisture balance.  We strongly recommend you consult with a safety specialist always prior to using any moisture balances for your safety.

The Sartorius MA160 moisture analyzer has a "Software Assistant Function" to start the development of your our test method parameters. See step by step how to test ketchup
Watch this video above as we highlight in this video the differences between the MA37 and MA160 since briefly looking at the units they seem the same but there are major differences.

So both the MA37 and MA160 deliver readability to 1 milligram. The average repeatability is ± 0.2% when you are using an initial sample weighing from 1-5 grams and when using a initial sample greater than 5 grams the repeatability is 0.05%. We always recommend a sample at least 5 grams since anything smaller is typically difficult to attain a good representative sample. Neither unit is recommended for plastic resin applications.

So what are the differences??

Although the infrared heating element looks similar the MA37 maximum output is 480W while the MA160 is 600W. More watts shortens time to attain temperature setting. The heating elements differ from a different alloy mix for the metal tubular heating element and Sartorius calls the MA160 element AURI.

MA37 has only the ability to save one (1) method while the MA160 can save up to 100 methods.

MA160 comes with "Sample Tongs" while it is an accessory for the MA37.

MA160 includes 3 ReproEasy Pads while no pads are included with the MA37. The ReproEasy Pads are used to verify the moisture analyzer is functioning within manufacturer specifications. The pad is a onetime use consumable item and additional pads are sold in packages of 10 pads. We recommend you download the user manual and reference the section "MA Performance Test" to learn more about this test feature available on both the MA37 and MA160. This is a great alternative to testing your moisture analyzer against sodium tartrate dihyrate. Using sodium tartrate dihyrate requires you to operate at 160C to release the chemically bonded two water molecules from Sodium Tartrate. The ReproEasy Pad you can run a performance test at 70C, 100C or 130C whichever temperature is closer to your actual sample you test normally.

The MA160 has a SD memory card slot verses the MA37 just has a dummy slot. You can import/export methods to the SD card. This is a nice feature for companies that implement "build alike" or create SOP implemented globally throughout their plants. One plant can develop the method for each different sample, download those methods to the SD card and the e-mail the file to other plants where they can copy the file to the SD card and then import them into the MA160 located in other locations. In the "Calibration Report" menu you can access the most recent calibration reports for the MA Performance Tests and external calibration adjustments up to 99 reports are saved per day. Calibration reports older than 30 days are automatically deleted. Again this information can be downloaded to the SD Card and the file e-mailed to the quality control or regulatory officer to meet compliance reporting requirements.

Another benefit purchasing the MA160 because it has the SD card is the "Results" menu. The analysis results can be viewed, exported or deleted. If you export the data to the SD card it is saved as an XML file and can be viewed with a web browser like Internet Explorer or Firefox. This is a great feature especially for paperless operations or if you need to print results and don't have a Sartorius YDP30 or YDP40 printer. All you need to do is save results to the SD card, open the file on your PC within a web browser and use the printer connected to your computer.

I would say the greatest feature the MA160 has that isn't available on the MA37 is "Method Assistant". Method Assistant helps you develop and refine methods in 3 easy steps. Its quick and ensures that all relevant parameters have been included for your moisture determination test. The Assistant prompts you to configure all relevant parameters, provides a practical range and prevents you entering implausible data. If you are running lots of different samples and not sure on the optimum temperature, whether you should use filter pad(s) The intuitive wizard asks you whether your sample consistency is a solid, fluid or paste. Method Assistant even asks if the sample is organic, inorganic or unknown.

Finally there is a 'Protective Mode" menu that is only available on the MA160. This allows you to password protect the MA160 moisture analyzer to ensure only authorized persons can make changes to the system settings. This video is a must see.
