A&D Weighing BM-300 Analytical Balance

The A&D Weighing BM-300 analytical balance is a good choice for labs that need to analyze and store large amounts of weighing data. 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 5000 data points. The BM-300 analytical balance 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. Calibration can be performed at any time with the push of a button while the auto calibration feature performs internal verification whenever a change in temperature is detected. The BM analytical balance series offers a large selection of accessories to facilitate additional and expanded functionality.
