China High Quality Portable Gas Detector Manufacturers – GDWG-V SF6 Gas Leak Detector (IR type, Double display) – HV Hipot

Product Description

GDWG-V SF6 Gas Leak Detector is infrared red type leak detector (NDIR technology) with double display. It is color INCELL TFT display and real-time shows SF6 concentration. It rapidly detects SF6 breaker, GIS leakage point and yearly leakage rate qualitatively and quantitatively. It is 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 0.01ppmv.
● When serious leakage or the SF6 gas concentration is up to 100%, it will not be polluted or damaged.

Features

● Color TFT In-Cell screen, double display, visual in sunlight.
● 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.
● Non-gas contact measurement features ensure that no sensor poisoning will occur at any concentration.
● The sensor constant temperature chamber can ensure that the sensor does not have temperature drift at any ambient temperature.
● Small size, easy to carry, suitable for on-site working.
● With gasbag non-slip straps, more comfortable to carry.
● Data storage up to 100groups.
● Super-light aluminum with full shielding shell.
● External package uses engineering plastic, with water-proof, dust-proof.
