Description
Overview
GAOTek industrial high resolution temperature process calibrator is a high precision hand-held signal measurement or output instrument, which can measure and output voltage, current, resistance, frequency, and thermocouple at the same time. Various industrial process signals, such as thermal resistance, can be used to calibrate pressure transducers with external high precision intelligent pressure modules. It can replace current signal source, electronic potentiometer, other measuring, and calibration instruments.
