MODEL PHM-100

The PHM-100 is a portable hand-held digital indicator for strain gage bridge type transducers such as load cells, torque sensors and pressure sensors. It provides bridge excitation, balance, span adjustment, shunt calibration, decimal point selection and digital display. When peak hold is in the on position, the highest static or dynamic signal is captured at less than one millisecond and displayed until reset. The PHM-100 operates on a standard 9 volt battery for 60 hours and is equipped with a low battery Indicator.

PHM-100 is a portable hand-held digital indicator.
