    GDSF-411CPD SF6 Gas Analyzer hits:
    General information

    GDSF-411CPD SF6 gas comprehensive analyzer is a portable device designed to measure SF6 gas dew point, purity and decomposition product. The core component with chilled mirror method is used to test dew point, European sensor with infrared method to test SF6 gas purity and electrochemical sensor from Membrapor to test SF6 gas decomposition product. Besides, we also adopt professional hardware chips and excellent software algorithms of STMicroelectronics.

     

    Application

    • Analysis of trace moisture, purity and decomposition products of SF6 gas electrical equipment for electric power
    • SF6 gas cylinder gas quality test
    • Quality test of SF6 gas for recovery and reuse
    • 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.

     

     

    Features

    • With imported high-precision sensor and self-calibration function, test results are more accurate all year round.
    • With polymer material design throughout gas pipeline from Legris, Camozzi and Swagelok, ensure no wall-clinging condition,and fast test speed.
    • Oil-free stainless steel regulating valve is adopted to ensure test accuracy.
    • Advanced software algorithm improves the test accuracy of imported sensors.
    • With flexible case configuration. User can assemble spare parts more easily.
    • Power on to detect, no need for oscillation.
    • Temperature conversion and pressure data correction.
    • Fuzzy computing technology.
    • High-power lithium power supply system can realize AC DC double power supply. No need for on-site AC power supply. Lithium battery can work continuously for more than 8 hours alone.
    • Anti-electromagnetic interference circuit design, to ensure the reliability of products.
    • USB communication, serial communication and wireless communication modules can be extended to realize PC communication and printing functions. (optional)
    • Mass storage, which can realize the storage function of 1000 groups of data.
    • Gas path pretreatment function can purify the test pipeline before the field test work, which shortens the test time. (optional)
    • With environment protection function. The instrument has a test gas recovery function, which can recycle the measured sulfur hexafluoride gas. (optional)
    • The test data is stable. Standard dew point value and the converted dew point value under 20℃ can be provided at the same time.
    • The purity measurement accuracy is 0.5% in the full range, which can be applied to measure high concentration SF6 gas.
    • The display of the best test flow area is clear and intuitive. Users can adjust the gas flow directly and quickly.
    • The air inlet adopts the design of miniature self-sealing joint, so the measured air path will not leak when it is broken.
