SF6 Gas Detection

Hi,
I am trying to locate a supplier of a personal atmosphere detector capable of giving a reading for SF6.

I am able to locate numerous suppliers of SF6 leak detectors capable of reading levels of low ppm, but we have a requirement to check voids below some SF6 switchgear before entering the space. There are occupational exposure limits for SF6, so there needs to be a quantitative display of the level of SF6 present.

Look forward to your replies. Many thanks.
Terry.
 
The most important thing for sf6 gas leak detecor is the SF6 sensor. There are generally two types of SF6 leak detection in the industry:
  1. Detection of leaks that only show concentration levels are typically divided into 0-10 levels. Depending on the amount of leakage, a strident alarm sound is emitted. Semiconductor sensors are commonly used, with low cost and low accuracy, and can only detect whether there is a leak, not the vaule of leakage.
  2. Infrared sensor SF6 gas leak detecor can display ppm values for leaks, with an effective detection range of 0-50 ppm or 0-1500 ppm. They are generally equipped with a miniature pump to speed up the contact between the leaked gas and the sensor, improving the detection response speed, and can test the leakage value.
