The measuring benches of AIDE GmbH Dessau work according to the principle of infrared absorption without moving parts. By using specially manufactured semiconductor sensors and new, pulsed high-power IR-sources made in germany, the detection of gases is possible even in the lowest ppm range. The AIDE-IR gas sensors have a high resolution and an extremely low noise.
