GDSF-311WP SF6 Dew Point and Purity Tester
GDSF-311WP is ideal instrument when it is necessary to test water content and purity of SF6 gas. The core component is DRYCAP series sensors produced by Finland Vaisala company. With professional hardware chips and excellent software algorithms of STMicroelectronics, we have produced a new generation of gas moisture test instrument.
● Moisture monitoring of SF6 gas electrical equipment for electric power
● SF6 gas cylinder gas quality test
● High purity gas manufacturing
● Semiconductor industry dry gas supply
● Research and development use
● Clean room/dry house monitoring
● Metal heat treatment site and laboratory industrial gas humidity detection, such as air, CO2, N2, H2, O2, SF6, He, Ar and other inert gases.
SF6 Humidity
● Measurement method: Resistive and Capacitive measurement principle
● Measurement range: dew point -80℃--+20℃(support ppmv)
● Accuracy: ±1℃
(when the dew point temperature is below 0 ℃, the sensor output is the frost point)
● Response time: 63% [90%]
+20→-20℃ Td 5s[45s]
-20→-60℃ Td 10s[240s]
● Resolution: 0.01℃
● Repeatability: ± 0.5 ℃
● Display unit: ℃, ppm, ℃P20(converted value at 20℃)
● Gas flow: 400-600ml/min
● Flow display: 0-1000mL digital flow meter
● Sample gas pressure: ≤1MPa
SF6 Purity
● Measurement method: TCD technology.
● Measuring range: 0 ~ 100% SF6.
● Accuracy and repeatability: ± 0.5%, nothing to do with the flow.
● Power supply: 220VAC±10%, 50Hz, AC/DC use, over-charge protection, continuous working is no lower than 8hours.
● Use environment temperature: -20--+60℃
● Environment humidity: 90%RH
● Measurement value influence: No effect of pressure and flow
● Dimension: 395*295*155mm
● Weight: about 2kg.
