Application of CA330 Thermal Resistance Calibration Instrument

RTD simulation

CA330 supports 14 types of thermistor outputs. The basic accuracy is as high as 0.3 ° C (typical value of PT1000), which is twice that of existing models and can perform high reliability testing.

applicationRTD measurement

CA330 can measure the output value of thermal resistance like a thermometer. The basic accuracy is as high as 0.3 ° C (typical of PT1000), which is twice that of existing models, and can perform multiple process temperature measurements for 14 different thermal resistors.
