Product Description

Main Feature

　　◆ Compact structure, small size, light weight, easy to carry;

　　◆ High degree of mechatronics, advanced technology and reliable performance;

　　◆ Large screen LCD, Chinese character menu, intuitive and simple;

　　◆ Mass storage, equipped with a micro printer, print test results at any time;

　　◆ Good sealing performance, no waste of SF6 gas during calibration;

　　◆ Both ends of the connecting air pipe are equipped with imported quick check valves, which are easy to operate and prevent water and air from entering the pipeline;

　　◆ The sampling point is equipped with an intelligent voltage protector, and the 220V voltage of the sampling point is incorrectly connected to the calibrator. It is safer to use;

　　◆ The temperature sensor is located in the gas pipeline of the instrument, which correctly reflects the gas temperature in the density relay, and the measurement is more accurate;

　　◆ Measure the alarm action and release pressure value of various SF6 gas density relays at any ambient temperature, and automatically convert them to the corresponding standard pressure value at 20°C to achieve the alarm performance verification of SF6 gas density relays;

　　◆ If the SF6 gas density relay to be calibrated is attached with a pressure gauge or density meter, the calibrator can also verify the accuracy of the pressure gauge or density meter;

　　◆ Standard pressure conversion from SF6 gas pressure to 20℃ at any ambient temperature. Conversion from standard pressure at 20℃ to pressure at any temperature
