This instrument is designed to measure the dew point parameters of SF₆ gas in high-voltage circuit breakers and GIS combined electrical appliances. A color LCD screen directly displays key data including dew point, micro moisture (ppm), ambient temperature, ambient humidity, as well as time and date.

Performance Features
★ Self-calibration: The sensor probe can automatically calibrate the zero point;
★ Fast and gas-saving: Each SF6 gas dew point measurement takes approximately 5 minutes;
★ Self-locking connector: Uses original German imported self-locking connectors, ensuring no gas leakage;
★ Data storage: Can store 200 sets of test data;
★ Curve function: Large screen displays the dew point measurement process as a curve;
★ RS232 interface: Can be connected to a PC serial port for data transmission;
★ Built-in power supply: Built-in 4Ah rechargeable lithium battery, providing 10 hours of continuous operation.
