Description
LR-Cal LHM description
The particularly versatile and high-precision handheld LR-Cal LHM is not only suitable for highly accurate measurements of pressures, forces, weights and torques on site, but above all for calibration and adjustment tasks - mobile and in the laboratory.
The analog/digital converter processes 50,000 digits, the internal sensors and the available external sensors (2mv/V) can be calibrated and linearized menu-driven.
