Digital Portable Thermometer

Digital Portable Thermometer


Description :
Libratherm Instruments offers Digital Portable Thermometer (Model DTM-21) mainly for Industrial use. It is an indispensable tool in every step of temperature measurement. It accepts various types of Cr/Al or RTD (Pt-100) sensing probes to measure the temperature of hot or cold flat/rotating/vibrating surfaces, powder, liquid, gas, furnaces, ovens, cold storage’s etc. It’s a handy instrument to cross check the temperature. It can measure the temperatur e from –100 oC to +1000 oC within ± 0.5% accuracy. DTM-21 is 9-volt battery operated, rugged, reliable, and field proven Digital thermometer.

Some of the above models are also available in suitable size flameproof enclosures for use in the hazardous environment.

Features :

• Indispensable tool for all industries for quick temperature measurement.
• Wide temperature range –100 oC to 1000 oC
• Accepts RTD (Pt-100) or Cr/Al probes or sensors.
