ANALYTICAL BALANCE -0.0001 g (0.1 mg)

Product Code: N/A

Categories: ANALYTICAL INSTRUMENTS, LABORATORY EQUIPMENTS

DR Labs DR-MA-220 & DR-MA-320 are electromagnetic technology based analytical balance of class I. It sports an automatic internal calibration. Automatic internal calibration is performed using an in-built standard mass attached to motor inside the machine. It is designed & programmed in such a way that the machine self-calibrates itself when certain parameters such as temperature, pressure, sensitivity is changed. It not only makes the machines more accurate but also very easy to use. You can recalibrate the machine by just pressing the CAL button and the machine will self calibrate. But if you wish you calibrate it externally using your own standard weight, MA-220, MA-320 gives you the freedom to calibrate the device using your external standard weight too.
