GDWG-V SF6 Gas Leak Detector (IR type, Double display)
Product Description
General 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.
