Gas detector
Based on infrared technology
Applications
- Locating and quantifying leakage at SF6 gas-filled equipment
- Determining leakage rates for final inspection of SF6 gas-filled equipment
Special Features
- Even the smallest concentrations of down to 0.6 ppmv can be detected
- Responds only to SF6 gas and is therefore insensitive to moisture and the usual volatile organic compounds (VOC)
- Easy operation
- Fast response time
- Calibration ex-works using certified test gases
Description
The model GIR-10 gas detector is used to detect even the smallest concentrations of SF6 gas, making it ideally suited for locating leakage and determining the size of it.
Infrared technology
Based on non-dispersive infrared technology (NDIR), model GIR-10 offers fast response times and reliable measured values – even with minor leakage.
Easy handling
This instrument is characterised by easy operation and good readability. Both the hand-held and the console case are equipped with an easy-to-read digital display. This allows reading the current SF6 gas values from any position.
The leakage detection is carried out using a hand-held, which has a flexible gooseneck with gas inlet on the front side. An exchangeable filter prevents particles from being sucked in, thus protecting the infrared sensor.
A pump in the console case provides continuous flow of the sucked-in gas mixture through the gas sample chamber of the infrared sensor.
If SF6 gas is already present in low concentrations in the measurement environment, this offset can be tared to 0 ppmv at the instrument. This makes leakage detection easier, as every measured value greater than 0 ppmv represents leakage.
Depending on the version, model GIR-10 sends an acoustic alarm when a defined concentration is exceeded.
