Ohaus MB45 moisture analyzer has a weighing capacity of 45 grams, with a readability of 0.001g and repeatability to 0.015% when using a sample greater than 10 grams. An integrated database stores up to 50 drying procedures for maximizing productivity, simply recall the test from memory and begin. Use the statistical function for simple tracking and recording of standard deviation over time, the MB45 does all the calculations and provides the end result.

Additional features the Ohaus MB45 moisture balances offers includes:

  • Ohaus MB45 utilizes a dot matrix graphic display for quick setup and use, displays % moisture, % solids, % regain, time, temp, weight, test ID, drying curve & statistics
  • Halogen heating lamp for even heating with and four enhanced heating options and an operating temperature range from 50° to 200°C in 1° increments
  • Four selectable automatic drying programs allow for easy one step drying, simply set the temperature and time, and begin

The Ohaus MB45 is a full featured, compact moisture analyzer for every budget! Perfect for environmental, quality control, food and beverage, chemical, pharmaceutical industries, and more, this fast, rugged analyzer gives you the flexibility you need and the accuracy you require for moisture determinations. Ohaus MB45 combines state-of-the-art heating with highly accurate weighing technology to deliver a faster, more precise method of moisture analysis. Review additional technical specifications on the Ohaus MB45 here.

If you already own the Ohaus MB45 moisture analyzer and you are looking for the consumable moisture pans you can purchase a box of 500 aluminum moisture pans for an extremely low cost compared to what Ohaus charges for these moisture pans if you bought them from Ohaus direct. We also sell moisture balance filter pads used to distribute the heat better, prevents skinning over (this is when bubbles form). You can purchase a box of 200 filter pads or buy a case of 4000 filter pads to save even more money.

Many people call us looking for the absolute best value Precision Weighing Balances can offer in a moisture balance for simple moisture determination applications like sludge wastewater applications and the answer again and again is the A&D ML-50. When price is the #1 factor and you want a quality moisture determination instrument to 1% moisture content determination then you should review the ML50 moisture balance HERE.

Before you buy any moisture balance be sure to see the Sartorius MA35 moisture analyzer. The Sartorius MA35 heating element is metal tubular and this provides more of an oven effect providing intense heat throughout the complete heating chamber thus allowing better drying to all sides of the sample (top, bottom and sides). Although the metal tubular design isn't the fastest design for drying to run the percent moisture test since metal tubular takes longer to heat up over a halogen bulb we feel it is the best method to determine moisture.

If you have any questions about your moisture application give us a call M-F 9-5 EST at 978-521-7095 and one of our experts can assist you in resolving your moisture determination application.

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 Ohaus MB45 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.


***WE DO NOT RECOMMEND THE MB-45 FOR PLASTIC APPLICATIONS OR FOR TESTING PLASTIC OR NYLON OR RESIN SAMPLES.  THE ONLY MOISTURE ANALYZER WE RECOMMEND FOR THIS APPLICATION IS THE MS70***

The moisture pans are from oil free weighing aluminum pans and provide even temperature across the pan.

Some people believe that they can reuse the pans but this is never recommended.  Although you might clean off the pan the stains leave material from your last test or even moisture when you attempted to clean the pan.  Others believe they can use a piece of aluminum foil paper but this isn't always smooth and creates crinkles and thus uneven drying.  Always, always, always use a new moisture pan for each test.

Glass fiber pads distribute the heat better, prevents skinning over (this is when bubbles form).

The fiber pads are binder-free borosilicate glass fiber and therefore contain no binders (no foreign materials) or inert.

Slurry samples or when test times are long the sample skins over, bubbles up or splatters when the moisture testing is running, we recommend using filter pads with the moisture pans.

For testing liquids the pads are a must.  Place the moisture pan and pad on the moisture balance, adjust the setting time to zero so the Sartorius MA35 moisture analyzer is in auto mode and run the test with no sample on the pad.  Many times the fiber pads can hold up to 2% moisture and this preps the pan and fiber pad to be moisture free and only takes typically 1 minute with the MA35 moisture analyzer.

Now with the dry filter pads if you are working with a liquidity substance 70% water or more place the sample with an eye dropper, syringe or pipette is a spiral pattern and then cover with the filter pad.

For slurries and anything with bumps and chucks like corn slurry we recommend using two pads making like a sandwich (bottom pad - test sample - top pad).  Place the pan on the moisture balance and then place one pad on your table and then using a syringe or spoon apply the sample to the pad in a spiral pattern and now cover with a second pad.  Slightly squish the sandwich you just made to break up any chucks and the filter pads will absorb the moisture.  Now place the two pads with your sample sandwiched in-between and run your test.  You'll find more consistent and repeatable rest using the two pads.
