Designed for weight, millivolt, and force measurement applications, Model PD6100 and explosion proof Model PD8-6100 feature 1-button zeroing of display, auto-zero adjustment to prevent drift, and panel-mounted or rugged, field-mounted enclosure. Tare/Reset Tare function enables meters to compensate for anomalies, such as sludge buildup at bottom of empty tank. Accepting mV input signals up to 300 mV (unipolar) and ±250 mV (bipolar), both meters are rated for max current of 350 mA at 10 V.
