The sensing element of TGS826 is a metal oxide semiconductor which has low conductivity in clean air. In the presence of a detectable gas, the sensor's conductivity increases depending on the gas concentration in the air. A simple electrical circuit can convert the change in conductivity to an output signal which corresponds to the gas concentration. (read more)

Net Safety's Single UV flame detector reacts to the ultra-violet radiation found in hydrocarbon, hydrogen, ammonia and sulphur fires - delivering accurate and reliable fire monitoring. As an added advantage, the Single UV does not react when exposed to incandescent or fluorescent lighting, heaters or sunlight - so false alarms are considerably reduced. (read more)

The Adixen Sensistor H2000 tracer gas leak detector is up to 1000X more sensitive than pressure decay testing and an economic alternative to helium testing. This industrial leak detector can measure pressure drop in order to disclose leaks and localize them with a safe mixture of N₂/H₂ as a trace gas. (read more)

Varian introduced a new series of helium mass spectrometer leak detectors for testing the integrity of systems, chambers, containers, and parts by using helium as a tracer gas. The new VS Series includes the portable VS PR02 leak detector and the mobile (cart mounted) VS MR15 and VS MD30 leak detectors. (read more)

TGS2444 is a new ammonia gas sensor fabricated with a screen printing technique. Its sensitivity to ammonia and cross sensitivity to alcohol is superior to conventional MOS sensors, making it possible to detect concentrations as low as 10ppm. (read more)
