Product Description

Infrared SF6 Gas Leak Detector SF6 Gas Leakage Detection Device

 

General InformationGDWG-V SF6 Gas Leak Detector is infrared red type leak detector (NDIR technology) with double display. 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.

 

Main 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

• OLED 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.
