■ functional features

▲ this product adopts 32-bit microprocessor and ti's high-speed signal processing chip for detection and control, with a high degree of integration. Mechatronics design, high precision, good repeatability and high reliability.

▲ equipped with large screen Chinese LCD, man-machine interface, simple operation, beautiful interface, and all parameters and states are clear at a glance.

▲ automatically complete the pressure measurement and 20 ℃ value conversion, so as to complete the dynamic automatic compensation between pressure and temperature. And display the pressure under the measured ambient temperature, the pressure under the ambient temperature at 20 ℃ and the ambient temperature.

▲ the problem of difficult field calibration of SF6 gas density relay is completely solved.

▲ it can store 50 groups of test results at the same time, and has the function of power failure data protection. It can query and print the previous test results at any time.

▲ in the calibration process, there is no need for constant temperature chamber, and SF6 gas density relay and pressure gauge can be calibrated within any effective temperature range.

▲ it is equipped with many types of transition joints. The density relay of most types of switches can be verified on site without disassembly.

▲ the gas consumption in the calibration process is very small, there is no waste of SF6 gas, the test cost is low, and there is no pollution to the environment.

▲ the core components are imported components with reliable performance.

▲ it can test one group of alarm signals and two groups of locking signals at the same time.

▲ this product is a portable tool, which is convenient and reliable. It is a good choice for the calibration of SF6 density relay.

▲ built in high-capacity rechargeable lithium battery, the instrument can work continuously for 8 hours, and the charging time is less than 4 hours.
