Product Description
HS620 Automatic Pressure Calibrator uses high performance DSP servo control technology and modular design, high stability. Combined with intelligent pressure calibrator ,that realize pressure transmitter, pressure switch automatic calibration function. It may self-test pressure leaking and automatically protect inside pressure system. Large touch screen,friendly english interface with inside help menu instruct users how to calibrate pressure instrument . Calibration data store automatically and count the calibration result.easy to query history information record and switching pressure unit.With addition of strong protect function  Once the set pressure values overpass pressure range ,the items will stop pressure generating. Meanwhile motor driver insideprotect automatically.
