Model SC 220 -Explosive Gas Detectors

The ExDetector SC 220 detects combustible gases and vapors within a range of 0 %-50 % LEL. It uses a rugged semiconductor gas sensor. It is often a practical alternative to sensors that cannot be used in atmospheres with catalyst poisons. The ExDetector SC 220 may be used as a stand-alone device, i.e. it can trigger safety responses independently without the use of a controller. It features integrated low-voltage switching outputs for pre-alarm, main alarm and detector error. It may also be connected conventionally to a central control unit. It can be used in explosion zone 2.
