Overview
Enviro Test Construct pressure transmitter 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. It can be used to calibrate pressure transducers with external high precision intelligent pressure modules. It can replace current signal sources, voltage signal sources, resistance boxes, electronic potentiometers, frequency meters and other measuring and calibration instruments.
