GS300M Toxic and Explosive Gas Detector Control Unit for Industrial use

GS300M - Toxic and Explosive Gas Detector Control Unit for Industrial use

Through the connection of 3 remote probe, the GS300M control unit has been designed and built according to European regulations to detect the presence of toxic and/or explosive gas.
Thanks to this and its other features, it is suitable for: civil use, industrial use and small underground car parks.
The GS300M control unit has three danger levels:
1st LEVEL, 1st Alarm. This was set to 8 % of L.E.L. (120ppm) for all probes.
2nd LEVEL, 2nd Alarm. This was set at 13% of L.E.L. (200ppm) for all probes.
3rd LEVEL, Main Alarm. This was set at 20 % of L.E.L. (300ppm) for all probes.
Other technical features make this control unit extremely versatile and reliable; for example, by using a series of microswitches it is possible to:
Select or disable the probe when not installed or faulty;
Select the type of gas to be detected (toxic or explosive);
Choose the relay functioning mode (pulsed or continuous);

Choose selection of the intrinsic safety.
