Gas monitor with self test

The system consists of an intrinsically safe sensor head communicating with a control module. Up to 9 control modules can be located in a 19”-rack where each combination sensor head - control module works as an independent gas detection system. Therefore the total system can be expanded without limitation. No new units sold anymore. Compur Monitors does support all existing systems with spare parts, consumables and service now and in future! 0-1,5/0-15 ppm Diagnostic unit
