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.
ApplicationHigh Voltage Switch EquipmentRotor vane of helicopterGas transmission systemTo detect fire extinguisherVentilation efficiency research of BuildingsTo detect danger
AdvantagesNo 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.
Features3.5inch 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.SpecificationMeasuring principle
