GDSF-311WP SF6 Gas Dew Point and Purity Tester

GDSF-311WP is ideal instrument when it is necessary to test water content and purity ofSF6 gas. The core component is DRYCAP series sensors produced by Finland Vaisalacompany. With professional hardware chips and excellent software algorithms ofSTMicroelectronics, we have produced a new generation of gas moisture test instrument.

Application

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.

FeaturesBetter than ±1ºCmeasurement accuracy.The whole channel polymer material design, ensures no water wall hangingphenomenon and guarantees the test speed.The oil-free stainless steel body regulating valve is used to ensure the accuracy of themeasured value.Advanced software algorithms improve the test accuracy of sensors.Combined chassis configuration solution, users can easily combine relatedinstruments and accessories. The overall package is carried, which makes the userhave a more relaxed experience.Start up test, no need to preheat and oscillate.Temperature conversion and pressure data correction.Fuzzy computing technology.High-power lithium battery power, realize AC and DC dual power supply. No on-siteAC power is required. Lithium battery power supply continues to work for more than 8hours without the need of an external power supply.Anti-electromagnetic interference circuit design to ensure product reliability.It can expand USB communication, serial communication, wireless communicationmodule, and realize the communication and printing functions of the upper computer.Large-capacity memory, which can realize 1000 sets of data storage functions.The test data is stable and can provide both standard dew point values and converteddew point values at 20ºC.The best test flow area shows that the user can adjust the gas flow intuitively andquickly. Reduce test time.The air inlet is designed with a miniature self-sealing joint, and the air path to betested will not leak when the air path is disconnected.
