▎Product Introduction ：
The RFM-2 Hybrid Gas Density Relay Calibrator is a portable calibration device designed for regular verification of density relays, density gauges, and pressure gauges used on SF₆/N₂/CF₄ mixed-gas electrical equipment to monitor gas density changes. It adopts advanced mechatronic design technology, equipped with high-precision pressure sensors, pressure regulating valves, and A/D converters, making it a highly integrated, high-precision, and highly reliable fully automatic intelligent calibration instrument. With built-in temperature compensation algorithms, it automatically converts calibration data obtained at non-20°C conditions to standard values at 20°C, completing the entire calibration process automatically without manual intervention.
▎Key Features ：
1.Fully automatic calibration.
2.With automatic temperature compensation function.
3.Built-in dot matrix printer, report-style printing format, 5.6-inch color screen display, touch screen control.
4.Supports both relative pressure calibration and absolute pressure calibration modes, supports USB 2.0, local data transfer, and calibration of pressure gauges and density meters.
5.Data storage function (can store 500 groups of data), power-off data protection function.
6.Equipped with self-calibration function.
7.Powered by high-capacity lithium battery, comes with various models of transition adapters.
