Nieaf NI T82 Thermometer
Nieaf NI T82 Thermometer
The thermometer NI T82 is a very practical instrument for measuring one or two temperature levels. As soon as the temperature probes are connected, the measured value will be displayed.
In case of two connected probes, the differential between measured emperatues, T1 and T2 can be indicated. The thermometer is suitable for type K and Type J probes, to be selected on the instrument.
Besides these functions, the meter can hold the minimum or maximum measured value (min-max hold) and the differential temperature can be indicated. This temperature is based on a reference that can be selected manually (REL).
The NI T82 can indicate oC and oF, hold the display values (Data Hold), indicate Low Battery and has Auto Power Off.
