Portable Thermometer – DTM-22

Portable Thermometer – DTM-22

Product Description :

DTM-22 – High Accuracy Industrial Handheld Thermometer – Universal.
DTM-22-RTD – Thermometer suitable only for Pt-100 probes.
DTM-22-TC – Thermometer suitable only for Thermocouple probes.

Indispensable tool for all temperature measurement.
Software linearized for guaranteed +/-0.1 or +/-1°C display accuracy.
User selectable UOM °C/°F.
Touch keys for MAX/MIN/HOLD/CLEAR functions.
Can be selected for any type of Thermocouple or Pt-100.
Works on very low power using a single 9V battery.
A single thermometer can be used with multiple types of probes.
User selectable thermocouple types like J, K, R, S, and B.

Applications: To measure the temperature of hot or cold flat / rotating / vibrating surface, solid surface, cylindrical surface, powder, liquid, gas, furnace, ovens, cold storage’s, hot mould, and to log the data on to the computer.
