Sartorius Entris323i-1S offers 320 grams weighing capacity with 0.001 grams graduations (3 decimal places). That is 1/1,000th of a gram or 1 milligrams. The Entris323i-1S offers all the features of the Entris323-1S 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 Entris323i-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 Entris323i-1S has a circular draft shield to lessen against air current interference keeping your results accurate and to the point.
The Sartorius Entris323-1S 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 Entris323i-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 Extend ED323S-CW. The Sartorius Extend ED line was phased-out and replaced with the Sartorius Practum313-1S, Quintix 313-1S or Secura 313-1S. 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 Entris323i-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.

If you own one of those RCBS or Ohaus 10-10 mechanical beam scales they only weighed to 0.1 grains so they weren't really that accurate for ammo reloaders that wants to reload bullets with the same amount of powder. These mechanical scales are almost from the dinosaur ages.
The video above shows the Sartorius Entris323-1S milligram balance that weighs to 0.02 grains (5x greater readability than the 10-10, 02gn x 5 = 0.1gn). The Entris323-1S is a big step up from other mechanical beam scales and it isn't a strain gauge scales like the Acculab VIC123, Sartorius AY123, Denver MXX123, but as this video shows if you want to weigh to 1 kernel of powder you need greater accuracy than a milligram. Since a kernel of powder weighs between 0.020 - 0.030 grains you'll need an analytical balance like the Sartorius Entris64-1S. People reloading for pistol and air rifles typical buy the Entris323-1S BUT long range benchrest shooter DO NOT since they need every round to the kernel and the Entris323-1S will only be accurate enough to 1 or 2 kernels. Benchrest and Class F rifle team member buy the Entris64-1S since it is 10 times more accurate than the Entris323-1S.
In the video above we use the Omega 2-Speed Powder Trickler to dispense one kernel of powder at a time. If you are a competitive benchrest that needs to reload ammo to the kernel of powder then watch this video and buy an analytical balance.
Just because a balance like the Entris323-1S offers readability to 0.02 grain divisions/graduations does not mean it is accurate to ± 0.02 grain. Readability is just what the balance's displays resolution. One needs to dig into the manufacturer's specification and look for the word "linearity" which is the accuracy of the balance. Depending on the manufacturer the linearity is ± 2d, 3d or some low cost Chinese made balances it could be 4d or 5d. The FX-120i linearity is stated as ± 2 divisions. The Entris323-1S increments in 0.02 grain divisions so the linearity is ± 0.04 grains. These manufacturer specs are performed by the manufacturer and done in controlled environments (temperature & humidity controlled, no static electricity issues, no radio frequency interference, perfectly stable air so there are no drafts). You have to have faith the manufacturer is honest in their testing and we have seen over and over again the no name brands stated specs do not correspond to the performance of the balance. Since testing is done in ideal environments you really can't expect the same performance and let's just say if the manufacturer states ± 2d with your environment you'll get ± 4d.
A kernel of Hodgon H4350 weighs between 0.020 - 0.030 grains per kernel. Each kernel weight varies. In the video above we use the Sartorius Entris64-1S and I like to say when you have your balance level, balance warmed up for at least 30 minutes, in a stable environment realistically you'll expect to have accuracy to 0.008 grains (0.002gn x 4d = +/-0.008gn). Now if you purchased a milligram balance like the Entris323-1S the readability and linearity would be 10 times less of an analytical balance so the best performance you could expect is 0.08 grains. If a kernel weighs between 0.020 - 0.030 grains per kernel there is no way a milligram balance can deliver the consistent weighing results the competition benchrest shooting is looking for which is knowing each round of ammunition has the same amount of powder. Having ammo with an extra kernel or short a kernel will result in the bullet being high or low of the target's bullseye.
The RCBS10-10 mechanical beam scale finest graduation is 0.1 grains. The large poise increments in 10 grain divisions, the cylindrical micrometer poise has graduation to 0.1 grains and uses a gauge that increments in 1 grain divisions. One 360 degree rotation of the micrometer poise yield 1 grain.
If we say the average weight of a kernel of H4350 is 0.025 grains then 4 kernels weigh 0.1 grains, which is the best readability the RCBS 10-10 offers. It is not the accuracy since you are moving parts, friction points and the agate bearing the fulcrum pivots on wears. We'll use the Omega 2 Speed Powder Trickler from Dandy Products and we will dispense one kernel at a time to see how many kernels it takes to move the beam of the 10-10.
For many years those competition shooters wanting to weigh powder to the kernel purchased the Sartorius GD503. Once the GD503 were sold out Precision Weighing balances alternative to the GD503 was the AND HR100a and finally in May of 2014 Sartorius re-entered the market with an affordable analytical balance called the Entris Series. The Entris64-1S weighs up to 926 grains & increments in 0.002 grain divisions.
We show in the video above how the Entris64-1S can weigh to the kernel using the Omega 2 Speed Powder Trickler from Dandy Products available at www.omegapowdertrickler.com
In the video below we offer an overview of the components of the Entris milligram balance and how to assemble. Calibration is simple using an optional external calibration mass. We demonstrate the fast response time, repeatable weighing results and features like the leveling bubble, adjustable feet, RS-232 interface and more.
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
