Description
Overview
GAOTek multifunction accuracy temperature process calibrator is a high precision hand-held signal measurement or output instrument, which can measure and output voltage, current, resistance, frequency, 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, voltage signal source, resistance box, electronic potentiometer, frequency meter.
