AND BM-20 Micro Balance, 22g, 0.001mg (1μg)

The AND BM-20 is the 22 gram capacity single range micro model of the BM series. It offers 0.0025 milligram repeatability for 1 gram and ±0.010 milligram linearity.

The typical minimum sample weight is 3.0 milligrams based on USP chapter 41.

The 0.001 milligram resolution is maintained throughout the entire capacity, so even after heavy containers and filter holders are tared samples can be weighed with microgram sensitivity.

Its stability and repeatability are somewhat lower than the BM-5 and higher than the BM-5D and BM-22.

The adjustable response characteristic keeps the measurement stable against air currents and vibration. An automatic repeatability test can be performed using the internal weight.

Data is stored in the internal memory as 200 weighing records, 100 records with date and time and 50 calibration records, and GLP, GMP, GCP and ISO compliant output can be obtained.

1 Microgram Across the Full 22 Gram Capacity

Offers 0.001 milligram readability over the whole weighing range without range switching, and results are read with the same sensitivity even after heavy containers are tared.

Built In Fanless Ionizer

Removes static charge from the sample and container and reduces unstable readings, one of the biggest problems of micro weighing.

The electrode life is approximately 10,000 hours and it is user replaceable.

Motor Driven Internal Calibration

Allows calibration without mounting a weight, while automatic calibration tracking temperature change protects measurement accuracy.

One Touch Calibration and Calibration Test Report

Calibration can be performed with one key. An error test can be run with the internal weight without making any sensitivity adjustment, and a report can be printed for daily checks.

Anti Static Glass Panes and AD-1676 Breeze Break

Sliding glass panes with interlockable doors block static from outside. The AD-1676 tabletop breeze break supplied as standard reduces deviations caused by air conditioning and air currents.

Adjustable Response Characteristic

Adapts to air current and vibration conditions with manual or automatic setting.

Automatic Repeatability Test

Allows you to regularly check the repeatability of the device using the internal weight.

GLP, GMP and ISO Compliant Data Output

Traceable records are kept with the internal memory, clock and AD-1688 external data logger, and output with a signature field is available.

Piece Counting and Percentage Weighing

Can count small parts down to a 0.1 mg unit mass and perform percentage weighing against a reference mass.
