Model of pressure instrument calibration device: GRZ150

Product Introduction
It is a complete measurement and calibration system for air pressure measuring instruments. The pressure instrument calibration device consists of a control acquisition system and an empty box pressure gauge calibration box. The control acquisition system includes an automatic pressure controller, a pressure standard (with a maximum allowable error of ± 0.2hPa), a 16 channel RS-232/RS-485 collector, an adjustable power supply, gas source, industrial computer, etc. The empty box pressure gauge calibration box provides a closed constant temperature testing room; The entire calibration device can provide automatic pressure control and temperature control. Through the matching calibration software, digital pressure sensors can be automatically calibrated, data collected, processed, and generate calibration certificates according to the calibration regulations. The calibration of empty box pressure gauges currently supports semi-automatic calibration.
