The mulpurpose high accurate handheld indictator is not only suitable for very LR-Cal LHM precise measurement of pressure in the field, but also specially as reference instrument for calibraon, verificaon and adjustment of pressure, force or torque reading instruments. The analog-digital converter‘s resoluon of 50,0000 digits works with all LR-Cal reference sensors with 2mV/V signal. Via menu it is possible to set zero-point and span as well as linearisaon with 5 points. The measurement rate of up to 4,800 measurements per second make this handheld instrument ideal for detecon of max. or min. values (PEAKs).
Comes with USB charger, factory calibration certificate, plastic carry case, and user manual.
