Description
Overview
GAOTek portable temperature process calibrator has instrument calibration system which is designed with blue LCD and keys, showing the high-end design concept and accurate control. The automatic calibration system can be controlled by keyboard or upper computer freely. No matter what kind of control, it can realize the automatic verification function and realize the automatic verification of instruments. It can be used for the calibration of pressure gauge and pressure gauge with reasonable structure.
Features
- The double closed-loop control scheme of pressure
- Pressure change rate is adopted
- It’s convenient to set the pressure output, fast
- Stable to control the pressure without overshoot
- Meets the verification regulations of relevant pressure instruments
- Automatic pressure making system has anti-overload protection
- It can be switched automatically or manually
- Function of combining automatic control and fine adjustment
- Conductive to the verification of pointer pressure gauge
- Real time display
- Computer software touch screen
- Verifiable Hart pressure transmitter
