Temperature and Humidity Measurement


The temperature of a substance is the degree of hotness or coldness of the substance. A hot substance is said to have a high temperature whereas a cold substance is said to have a low temperature. Therefore, the temperature of a substance is an indication of the average kinetic energy of the molecules of the substance. Heat always flow from a body at higher temperature to the body at lower temperature. So, we can also say that temperature of a body is the property which governs the flow of heat. It can easily be demonstrated as follows:

When two objects of the same material are placed together, the object with higher temperature cools while the cooler object gets warmer until a point is reached after which no more changes occurs.


Relative humidity is the ratio of the partial pressure of water vapor to the equilibrium vapor pressure of water at a given temperature. Relative humidity depends on temperature and the pressure of the system of interest. The same amount of water vapor results in higher relative humidity in cool air than warm air.

Thermal On-Site Calibration Capability

Using the more accurate master equipment we can calibrate the Instruments and equipment as per the National / International standard of VSSC, AMS 2750, CQI 9, DKD-R5-7, IEC 60068, API and Customer Specified Method.

Perfect Calibration Centre Pvt Ltd’s relative humidity (RH) capability ranges from 15%RH to 95%RH at 25°C to 70°C using high accuracy and low uncertainty Temperature and Humidity Transmitter which also the calibrated National Physical Laboratory (NPL-India).
