China GDSF-311WP Automatic SF6 Gas Dew Point Multifunctional Analyzer Purity Decomposition Integrated Tester

GDSF-311WP Automatic SF6 Gas Dew Point Multifunctional Analyzer Purity Decomposition Integrated 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.

Application

Moisture monitoring of SF6 gas electrical equipment for electric powerSF6 gas cylinder gas quality testHigh purity gas manufacturingSemiconductor industry dry gas supplyResearch and development useClean room/dry house monitoringmetal heat treatment site and laboratory industrial gas humidity detection, such as air,CO2, N2, H2, O2, SF6, He, Ar and other inert gases.

Features

Better than ±1ºC measurement accuracy.The whole channel polymer material design, ensures no water wall hanging phenomenon and guarantees the test speed.The oil-free stainless steel body regulating valve is used to ensure the accuracy of the measured value.Advanced software algorithms improve the test accuracy of sensors.Combined chassis configuration solution, users can easily combine related instruments and accessories. The overall package is carried, which makes the user have 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-site AC power is required. Lithium battery power supply continues to work for more than 8 hours 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 communication module, 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 converted dew point values at 20ºC.The best test flow area shows that the user can adjust the gas flow intuitively and quickly. Reduce test time.The air inlet is designed with a miniature self-sealing joint, and the air path to be tested will not leak when the air path is disconnected.
