Product Description

Customized 4 Channel SF6 Gas Leakage Detecting System GDWG


I. General information

GDWG SF₆ Gas Leak Detecting and Measuring Systems high precision and sensitivity detecting system, which use NDIR technology principle and pumping cycle principle. It is used to detect few SF₆ gas in the pipe quantitatively and qualitatively. Based on the design principle of infrared (detecting SF₆ gas wavelength 10.2-10.6μm), the SF₆ detection will be accurate.

Application

SF₆ detection and analysis of pipe type
SF₆ detection and analysis of storage container

Benefits
 

1. No radiation.
2. No need to replace high pressure high pure argon gas regularly.
3. No need to approach high pressure gas.
4. No need to replace sensors regularly, cost-effective.
5. Stable performance, low maintenance cost. No need to make linear calibration every year.
6. No affect by moisture and environment pollution.
7. Detection sensitivity is up to 0.1ppmv and 0.05ppmv.
8. When serious leakage or the SF₆ gas concentration is up to 100%, it will not be polluted or damaged.

II. Features
 

1. 3.5inch OLED display.
2. One screen display SF₆ gas concentration, temperature and humidity, battery indication, time and pump status.
3. Friendly human machine interface.
4. Fast measurement speed, up to10s to achieve stable data.
5. Only response for SF₆ gas, not for other gas.
6. Make sure that no sensor poisoning occurs at any concentration.
7. Small size, easy to carry, suitable for on-site working.
8. Super-light aluminum with full shielding shell.
9. Diaphragm pump suction sampling mode to ensure the tightness of the test gas path.
