ET2725 Multifunctional Process Calibrator

Short Description:

ET2725A,ET2725B,ET2726A,ET2726B multifunctional process Calibration instrument is a high precision hand-held signal measurement / 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 and other measuring and calibration instruments. Mainly used in industrial field signal calibration, fault diagnosis; also applicable to chemical, military and all kinds of research institutes, real Signal measurement and calibration in laboratory.
