    GDWG-IV SF6 Gas Leakage Detector hits:

    General Information


    GDWG-IV SF6 Gas Leak Detector is infrared red type leak detector (NDIR technology). It is color OLED display and real-time shows SF6 concentration. It rapidly detects SF6 breaker, GIS leakage point and yearly leakage rate qualitatively and quantitatively. It’s a good device suitable for power supply department, installation and overhaul unit, power test institute.


    Application

    • High Voltage Switch Equipment
    • Rotor vane of helicopter
    • Gas transmission system
    • To detect fire extinguisher
    • Ventilation efficiency research of Buildings
    • To detect danger


    Advantages

    • No radiation.
    • No need to replace high pressure high pure argon gas regularly.
    • No need to approach high pressure gas.
    • No need to replace sensors regularly, cost-effective.
    • Stable performance, low maintenance cost. No need to make linear calibration every year.
    • No affect by moisture and environment pollution.
    • High sensitivity, up to 0.1ppmv (0.01ppmv for option.)
    • When serious leakage or the SF6 gas concentration is up to 100%, it will not be polluted or damaged.


    Features

    • 3.5inch OLED display.
    • Built-in Lithium battery.
    • User-defined alarm with sound and light.
    • High sensitivity and good stability.
    • Fast measurement speed, time is up to 3s.
    • Temperature and pressure compensation.
    • Only response for SF6 gas, not for other gas.
    • Small size, easy to carry, suitable for on-site working.
    • With gasbag non-slip straps, more comfortable to carry.
    • Data storage up to 8000groups.
    • Super-light aluminum with full shielding shell.
    • External package uses engineering plastic, with waterproof, dust-proof.
