SF6 comprehensive tester combines the tests of humidity of SF6, purity of SF6 and it integrates the functions which were originally fulfilled by tow instruments into one instrument. One site measurement can fulfill the test of three targets. It greatly saves the gas in the equipment, reduces the work amount of the users and improve the work efficiency.
SF6 comprehensive tester enjoys the excellent capabilities because it fully adopts the best foreign sensor, Finnish Vaisala for humidity, the thermal conductivity sensor with temperature compensation for purity are the imported products. It adopts the LCD display with real-time display of all parameters. It enjoys the overall fool-operation and large storage of information. It has chargable batteries inside for either alternating or direct current.
Humidity of SF6:
Measurement range: Dew point: -80~+20℃(support ppmv and so on)
Precision of dew point: ±0.5℃
Resolution ratio: dew point 0.1℃ or 0.1ppm
Flow of gas: when measuring humidity:0.8~0.9L/min,when measuring purity:0.5~0.7L/min
The electric quality flow meter, the flow speed of the sample gas will not be influenced.
Pressure measurement: 0~1.0MPa
Probe protection: stainless steel sintered filter
Purity of SF6:
Range: 0~100% SF6;
Precision and repeatability: ±0.5%,have nothing to do with the flow;
SF6 decomposition products
