The temperature calibrator is mainly used for the calibration and maintenance of temperature components (thermocouples, platinum resistors, thermometers), temperature transmitters (sensors), temperature switches and temperature display instruments. Origin of temperature calibrator: During the use of industrial sites, many industries involve temperature, and temperature generally uses on-site sensors (PT100 thermal resistors, thermocouples, etc.) and on-site display instruments (digital display meters, temperature controllers, etc.) instrument, recorder, etc.) to measure. During long-term use, the accuracy of the detection instrument may gradually decrease, thus affecting product quality, production, etc. And if these instruments are disassembled and returned to the manufacturer for testing, it will be more troublesome, so a relatively high-precision calibrator is needed to test their accuracy. The temperature verifier is a comprehensive instrument including a calibration system, a recording analysis system, a sensor system and other equipment. ?
