ZXMD-2000 Intelligent SF6 Density Relay Calibrator

The instrument uses a high-precision pressure sensor and a high-speed A / D converter, combined with a 32-bit high-performance microprocessor to perform performance verification on various SF6 density relays, and can accurately measure the pressure value at the current temperature when the signal is activated. It can convert any ambient temperature to the standard pressure at 20 ℃, and can immediately print and store the test data for reference, and at the same time automatically identify the faults during the test. This product is easy to carry, simple to operate, high in test accuracy, strong in stability and good in reliability, reflecting the "intelligent" characteristics of the instrument.
