Pressure Calibrator

SPMK221G automatic pressure calibrator includes pressure generation, pressure measurement, electrical signal measurement and output, and HART communication functions. It is suitable for the calibration of on-site pressure instruments. SPMK221G adopts full intelligent control, which can quickly and accurately output the set pressure. SPMK221G has made a special treatment for the convenience and practicability of the instrument interface, which can help the staff to efficiently, high-quality and safely complete the rapid calibration of pointer instruments, pressure transmitters, pressure switches and other instruments. The HART function can be used to complete the calibration of the smart pressure transmitter.
