? 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.
?With self-calibration function, ensure the stability and reliability of moisture, purity, and decomposition detection data throughout the year.
??All gas path with high 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.
??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 20℃.
??Purity measurement accuracy is 0.5% in the full range. It can be applied to the measurement of high concentration SF6 gas and 70% content SF6 gas.
??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.
?With internal pump, to pump back SF6 gas to stored cylinder.
