Description

LR-Cal LHM handheld indicator for pressure, force and torqueThe multipurpose high accuracte handheld indicator LR-Cal LHM is not only suitable for very precise measurement of pressure, force and torque in the field, but also specially as reference instrument for calibration, verification and adjustment of pressure, force and torque reading instruments. The analog-digital converter's resolution of 50,000 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 linearisation with 5 points.

The measurement rate of up to 4,800 measurements per seconds make this handheld instrument ideal for detection of Max or Min values (PEAKs).
