Analytical Lab Balance
The HR-AZ Series of compact analytical balances are fast, accurate and reliable. They feature solid construction based on the A&D Super Hybrid Sensor (SHS) technology which has delivered consistent weighing results day-in and day-out in thousands of laboratories and production facilities worldwide. The HR-AZ models add highly reliable internal calibration. One-touch automatic calibration ensures consistent balance accuracy. The HR-A and HR-AZ meet today's demanding needs in Laboratory, Quality Control, Quality Assurance, Production environments and deliver performance with convenience in a compact footprint.

A&D Weighing HR-A/HR-AZ series analytical balances come in several weighing capacities to accommodate your specific laboratory weighing needs.  Choose between 102 grams to 252 gram weighing capacity. The HR-A series offers external calibration and requires the purchase of an optional calibration mass while the HR-AZ features motorized internal calibration. Both series offer a tenth of a milligram resolutions with a large breeze break for precise weighing.  Get accurate weighing results with the latest analytical balance from A&D Weighing.

AND Weighing

The A&D HR-A/HR-AZ has a programmable unit conversion function. It multiplies the weight data in grams by an arbitrary coefficient set in the function table and displays the result. The coefficient must be within the range between the minimum (0.000001) and maximum (10000). If the coefficient set is beyond the range, an error is displayed and the balance returns to the coefficient setting mode, prompting to enter an appropriate value. A coefficient of 1 was set at the factory.
The HR100-AZ will offer equivalent performance to the Sartorius Entris, but the HR-100AZ has motorized internal calibration which is a real nice feature to have since you should always calibrate your balance prior to weighing. Having the motorized calibration with the HR100-AZ you just press the "CAL" button and the internal motor drops the weight and performs calibration.

Sartorius Entris64-1S with the Omega 2-Speed Electric Powder Trickler can deliver the results the competitive benchrest needs to reload ammo to the kernel of powder. We use Hogdgon H4350 powder and show how the powder weighs between 0.020 -- 0.030 grains and how easy you can weigh accurate charges to the kernel. To weigh to the kernel of powder you need an analytical balance the weighs to 0.0001 grams. When the Sartorius Entris64-1S weigh mode is configured to grains the balance increments in 0.002 grain divisions. You will not be able to know every bullet is weighed to the kernel of powder with a milligram balance (0.001g) since most milligram balances increment in only 0.02 grains (See this video for proof).

The shatterproof anti static breeze break is removable for easy cleaning.

The rugged, shatterproof draftshield with anti-static coating makes the HR-A/AZ safe for challenging applications where contamination is a potential concern especially with pharmaceutical weighing application with FDA requirements or food weighing where HACCP requirements restrict a breeze break made of glass.

Rotary doors mean that the balance takes up no extra space when the doors are open. The HR-A Series analytical lab balances are perfectly at home in the tight confines of glove boxes and fume hoods. Crowded academic lab benches are no problem: set-up 2 balances back-to-back.

Breeze break top pivots left or right to allow easy access to flasks and beakers.
In the video above we demonstrate the Sartorius Entris224-1S analytical balance and how easy calibration is when you purchase the optional calibration mass. The Satorius Entris 4 decimal place balances offer a large draftshield with 3 sliding doors. See the quick settling time as we place calibration weights on the weighing platform. Get a better understanding of what each keypad does and how you can enter into the balance configuration menu to change the factory default setting to better meet your specific weighing requirements. The Sartorius Entris is easy to configure to optimize for your individual weighing application.

Learn more about the AND FX-700CT as we demonstrate the balance and show you all the features this precision milligram weighing instrument offers. Basically the FX-700CT (152g x 0.001g) is the same balance as the HR-150a (152g x 0.0001g) but the FX-700CT displays 1/10 the resolution. If you want to learn more about the HR-a Series this video is well worth watching.
Need more accuracy? Do you need a 5 decimal place gram balance? The Sartorius Secura and Quintix semi microbalances are amazing. In the YouTube video above you will see the Sartorius Secura225D-1S semi microbalance [0-120g x 0.01mg] [120-220g x 0.1mg]. We highlight the intuitive operation using the SmartTouch user interface that is so easy to use you'll probably never need to reference the user manual. We also demonstrate the ergonomic draftshield and show how easy it is to dismantle the balance for easy cleaning.

Also you'll get a close up view of the new "collection container". The collection container is designed to keep the spill from entering the lab balance that could cause potential damage to the balance. Sartorius' revolutionary "collection container" features a rimmed design to keep the spill from entering if you happen to spill any liquid or granular samples while weighing.

If the Secura225D-1S is more balance than you need for your weighing application then be sure to see the Secura 125-1S, Sartorius Quintix125D-1S or Sartorius Quintix65-1S. Sartorius is our #1 selling laboratory weighing balances since they are the leaders in building high quality weighing instruments.
