  • Software: Compatible with the free LR-Cal LDM-COM software for data management.

The multipurpose accurate handheld indictator LR-Cal LHM is not only suitable for high very precise measurement of pressure, force and torque in the field, but also specially as reference instrument for calibration, and adjustment of pressure, force or verification torque reading instruments. The analog-digital converter‘s resolution of 50,0000 digits  works with all LR-Cal LHM-TP16 reference sensors with 2mV/V signal. Via menu it is possible to set zero-point and span as well as linearisation with 5 points.
The measurement rate of up to 4,800 measurements per second make this handheld instrument ideal for detection of max. or min. values (PEAKs).
