The HHM25 is no longer available. Please contact our Temperature Engineering department for possible alternatives.

The Model HHM25 is a portable and versatile true RMS multimeter with a 4 1/2 digit display. Aside from its full DMM and single input temperature measurement functions, an available temperature socket permits three simultaneous temperature measurements. An optional probe measures relative humidity from 5 to 95%. Both the humidity probe and thermocouple adaptor are included in the HHM25-KIT, which also includes a rugged carrying case. The HHM25 measures voltage from 0.01 mV to 1000 Vdc or 1000 ac, current from 0.01 mA to 10 A for ac and dc, frequency from 1 Hz to 199.99 kHz, capacitance from 0.001 nF to 99.99 µF, resistance from 400 Ohm to 40 MOhm, and temperature from -346 to 2498°F (-200 to 1370°C). Additional features include true RMS, min/max readings, auto range for voltage and resistance readings, relative and zero set, zoom and null capabilities. The front panel display indicates the measurement function, measurement units, thermocouple (T1, T2, T1-T2) or relative humidity probe, display hold, overrange and low battery warnings and also has a bargraph display.
