JKMD20 SF6 gas density relay calibrator

Main functions and features:
1. The calibrator adopts a color high brightness LCD touch screen as the human-machine interface, with a fully Chinese interface for easy operation and real-time display of various settings/measurement data.
2. Its core uses SMC's pressure control components and MEAS's aerospace grade high-precision pressure sensors and high-speed A/D converters. Combined with a 32-bit high-performance microprocessor, it can perform performance verification on various SF6 gas density relays, accurately measure the pressure value at the current temperature when the signal is activated, and automatically convert the standard pressure at 20 ℃ for any ambient temperature.
3. And it has printing, storage, and USB flash drive transfer functions, while automatically identifying faults during the testing process.
4. The built-in large capacity rechargeable lithium battery pack provides long standby time.
5. This product is easy to carry, easy to operate, has high testing accuracy, strong stability, and good reliability, reflecting the "intelligent" characteristics of the instrument.
