JC-9000 Type SF6 Density Relay Calibration InstrumentDetailed product description：

The JC-9000 SF6 density relay calibration instrument adopts precision imported parts. Through high-precision pressure sensors and high-precision A/D and D/A converters, combined with high-performance 32-bit ARM microcontrollers and TI's high-speed signal processing chips, it can automatically complete the calibration of SF6 density relays. It can accurately measure the pressure value at the current temperature when the signal is activated and automatically convert the standard pressure at any ambient temperature up to 20 ℃. It can automatically print test data and store it for future reference. The entire process does not require manual intervention and automatically identifies faults during the testing process, reflecting the "intelligent" characteristics of the instrument. The instrument has the characteristics of high precision, high stability, and high reliability.

Storage and transportation
The JC-9000 SF6 density relay calibrator is a precision electronic product that should be placed at a temperature of -30 to 70 ℃, a relative humidity of no more than 90%, and the air should not contain gases that can cause corrosion.
The transportation of the calibration instrument should avoid severe vibration and impact, and prevent rain and snow from soaking it.
Verification gas source: Due to the national security inspection department's prohibition on transportation, it can only be inflated at the user's location or test site (preferably at a professional inflation point, if there are no professional inflation conditions, it can be inflated by oneself)
