Sartorius Entris423i-1S offers 420 grams weighing capacity with 0.001 grams. Simple design, fast stabilization and affordably priced. The Entris423i-1S offers all the features of the Entris423-1S with the added feature of motorized internal calibration adjustment, minimizing the need for external calibration weights. The internal motorized calibration function provides optimal weighing accuracy and operating convenience.

Calibration is simple with the Entris423i-1S. Simply a press of the "Cal" button and the built-in motorized calibration weight located in the housing is applied and removed automatically for internal calibration. Calibration is the determination of any difference between the measured value displayed and the true weight (mass) of a sample.

Sartorius Entris milligram balances all feature a built-in RS-232 interface enabling you to transfer the weighing results to a computer or connect to the Sartorius YDP20-OCE printer. The Entris423i-1S has a circular draft shield to lessen against air current interference keeping your results accurate and to the point.

The Sartorius Entris423-1S has several weighing applications (Weighing, Density, Percentage, Counting, Unstable Conditions, & Conversion). Unstable Conditions also known as dynamic animal weighing application allows this high precision balance to weigh small insects that may be moving on the weighing pan accurately. Parts counting is another great application allowing this high accuracy balance to easily count those extremely small and lightweight parts the typical counting scales can't even sense the weight.

If you compare the specifications of many milligram balances on paper, they all look the same - if you've seen one, you've seen them all. But in the real world there is more to a milligram scale than just its technical specifications. The Sartorius Entris423i-1S has been specially designed for effective and reliable weighing in daily lab routines. This is where more powerful technology and application oriented operation and features make all the difference.

Using the latest magnetic force restoration weight sensing technology the Sartorius patented monolithic weight cell ensures high performance accurate weight readings. Sartorius utilizes a unique robotically etched monolithic weigh cell, which ensures long-term high accuracy. Sartorius Entris Series features the latest powerful microprocessor technology, shortening the response times for faster results. Reliable weighing results, all of the time - even under less than ideal ambient conditions, thanks to the Entris' highly sophisticated digital compensation algorithms.

Ease of use. When you need to get a heavy workload of repetitive applications done fast and reliably, day and day out, the last thing you need is a lab balance so complicated that it causes operating errors and wastes your valuable time as a result. Welcome to your Entris balance comfort zone: a simple, easy-to-understand control panel, key function assignments and the easy-to-read display are ideal for efficient weighing in your lab. User friendly operation: short, plain English text prompts and cursor keys for navigation make it simple for you to configure the balance to meet your individual requirements. The level indicator is positioned conveniently right next to the display so that checking whether the balance is level becomes "second nature" to the operator.

Sartorius products are manufactured with ISO9001 standards and have the CE mark. Sartorius has been proving their trustworthiness thanks to their top-of-the-line technology that ensures maximum accuracy. Sartorius begin building balances in 1871 and holds the Guinness Book of World Record for the most accurate balance in the world. When you have an excellent reputation and image in the technologically sophisticated field of weighing metrology there is no question Sartorius should be your only choice.

The Sartorius Entris Series consists 3 Analytical models (4 decimal places), 4 Milligram Balances (3 decimal places), 5 Precision Balances (2 decimal places) & 3 Precision Scales (1 decimal place) and you choose with internal calibration or without internal calibration. See the Complete Entris Series here.

The Sartorius Entris423i-1S is the replacement for the discontinued Sartorius Extend ED423S-CW. The Sartorius Extend ED line was phased-out and replaced with the Sartorius Practum 513-1S, Quintix 513-1S or Secura 513-1S. The Secura, Quintix and Practum balances introduced in 2013 featured an entirely new cutting edge design offering with a touch screen display with graphical user interface. These new touch screen balances are very nice and offer advanced weighing applications, but they are also expensive and for some people they prefer tactile keypad buttons over a touchscreen. The Sartorius Entris423i-1S is the same platform, housing, weigh sensor and embedded software as the Sartorius Extend. The only difference is a new display overlay, new microprocessor and the electronics used are RoHS (Restriction of Hazardous Substances) compliant. The overall operation of the Extend and Entris are the same.

We understand purchasing an milligram balance is a major capital expense and if you have any questions give us a call and one of our weighing experts can discuss your weighing application and get you the most affordable balance for your weighing needs.

For a limited time we are offering Free shipping via UPS Ground in the lower 48 states for the Sartorius Entris423i-1S.

  • Intuitive high contrast backlit display: Icons to tell you at a glance which application you are using.

  • External Calibration: To ensure the highest weighing accuracy at all times with the simple press of the calibration key walks you through the calibration automatically (requires you have a 200 gram cal weight).

  • Keypad: All buttons / keypads are micro switches offering better reliability and positive click so you'll know when you pressed the button.

  • Multiple weighing modes including: Grams, Kilograms, Carats, Pounds, Ounces, Troy ounces, Hong Kong taels, Singapore tales, Taiwanese taels, Grains, Pennyweights, Milligrams, Parts per pound, Chinese taels, mommes, Austrian carats, Tola, Baht, Mesghal, Tons, Pounds:Ounces, Newton.
 
specific gravity weigh below balance
 
In the video below we show you the excellent eccentric loading characteristics of the Sartorius Entris Balances. See as a calibration weight is placed in the center of 4 quadrants on the platform how the Sartorius Entris measures the weight accurately. Not all digital balances weigh accurately and if you own a laboratory balance other than Sartorius we doubt it compares to the Sartorius Entris. If you own an older Sartorius balance or someone tries to give you a deal on a used or discontinued Sartorius balance just forget it and buy the Entris.

To test eccentric loading we place a weight on the center of the weighing platform and record the weight. Now place the same item in 45-degree directions (front left, front right, rear right, and rear left) and compared to the measurement at the center. Compare the weighing results and if you have eccentric errors it just might be time to retire that balance and purchase a new Sartorius Entris.
 
 
In the video below we offer a general overview of the Sartorius Entris precision lab balance. We highlight the features, functions and operation of the Sartorius Entris precision balance. See some of the available accessories for the Sartorius Entris like the optional data printer, RS232 cable, calibration weights and weighing below hook.
 
 
In the video below we walk you through the menu configuration settings & how to enable or disable weighing applications. The factory default is "weigh" and the weight unit is set to grams only. Easily change this to "Unit" allowing you to toggle an additional 4 weighing units, "Count" for parts counting plus the ability to configure a desired reference sample quantity from 1 to 10, "Percent" for percent weighing proportional to a reference weight commonly used in formulation especially ink mixing, "Animal Weighing" for weighing live insects or small critters, or "Density" for density determination and specific gravity.

See how to configure the Sartorius Entris precision balance changing the factory default setting for the primary weigh unit of grams to pounds. We'll walk you through the steps so you can configure your Entris balance to toggle up to 4 additional different weight units
