Gastron developed fixed gas sampling and detection systems with its core technology of gas
nsensors. A dependable system was developed through decades of know-how regarding chemical
nreactions. An immediate response time is thus a key feature of the system. The system was
ndeveloped with cutting edge gas sensor technology. More than 90% of components including gas
nsensors are produced by Gastron at its facility, unlike other gas detector manufacturers who
nsimply purchase key components (detectors and sensors) from other suppliers. This helps to
nmake Gastrons prices much more competitive than those of other makers.
