ETYL331 Portable High Precision Pressure Calibrator
Browse through: Date of issue:2020-01-10



    The pressure calibrator has the measurement function of pressure, current, voltage and resistance, and has high measurement accuracy. It can calibrate pressure transmitter, pressure switch and pressure gauge. Built-in HART function, instead of HART hand-operated device, is used to set or calibrate the range of HART transmitter, force the output current of HART transmitter to set the value, set the linear or square-opening function, can carry out HART zero clearance for pressure sensor, and it is more convenient to use than HART hand-operated device.
    It is suitable for field and laboratory use. It can be connected with the full automatic pressure calibration platform. It can be used as an external pressure module of te pressure calibration platform. It can also be connected with various pressure sources to form a pressure calibration system.
    It can communicate with computer through RS232 to realize remote control, data processing and printing verification records.
    The display screen adopts a 2.8 inch color screen, which has a clear display interface and rich display content, and its interface content is still clear and visible in the dark environment.
