Description:
Libratherm offers Precision Industrial Portable Thermometer (Model DTM-22), which is designed using the latest low power, high speed microcontroller for accurate measurement of wide range of temperature and hence it is an indispensable tool in the industry for cross checking the temperature.
Single instrument can accept multiple type of sensors, such as Pt-100 or J, K, R, S, or B type of thermocouples. The selection is possible through touch key pad. Thermocouple and Pt-100 curves are software linearized for +-0.1% of display accuracy.
Various types of interchangeable probes can be used to measure the temperature. Industrial standard Omega make male/female connectors are provided for the sensor connections or for connecting floating leads of the external thermocouple already inside the furnace or oven or any hot or cold system. Other useful features allows user to record maximum and minimum temperature, freeze the measured reading and select the unit of measurement either in OC or OF.
White Back lit LCD to read the display in the dark area. Serial interface is optionally available for logging the data on to the PC using RS232 adapter. DTM-22 works on single 9V battery or on external 9V adapter.
Application:
- 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, etc…… and to log the data on to the computer .

Libratherm offers Precision Industrial Portable Hygro-Thermometer (Model HTM-22), which is designed by using the latest low power, high speed microcontroller for accurate measurement of Temperature and Relative Humidity. It is an indispensable tool in the industry for cross checking the atmospheric T + Rh. It can be easily carried by field engineers to carry out measurement at critical areas.
Single instrument can be used for both Temperature and Humidity, the display shows the reading one at a time with respective unit of measurement at a regular switching interval of 5 seconds.
The switching can be paused by pressing oC / %Rh membrane key in the front.Other useful features allows user to record maximum and minimum T + Rh, freeze or Hold the measured reading and select the unit of measurement either in OC or %.
White Back lit LCD to read the display in the dark area. Serial interface is optionally available for logging the data on to the PC using RS232 adapter. HTM-22 works on single 9V battery or on
external 9V adapter.
Application:
To measure the T + Rh in computer server room, laboratory, AHU ducts, Stability chamber, cold storage, Incubators, Ware houses, green houses, etc…
