The A&D Weighing BM-20 Micro Balance is ideal for a laboratories requiring extremely precise measurements and sample data management. Internal memory can store up to 200 sets of weighing data and 50 sets of calibration data and the included AD-1688 can store up to an additional 5000 data points. The BM-20 features a built in fan-less internal ionizer to eliminate statically charged products, a large weighing chamber, and anti static glass to block out electrical interference. The balance can be calibrated at any time with the push of a button and the auto calibration feature allows the BM-20 micro balance to calibrate itself whenever it senses a change in temperature. The BM series feature multiple additional accessories to offer a larger variety of functions.
