iQguard Car Park Gas Detection Sensor

iQGuard carpark gas detection sensor

Ampcontrol's iQguard carpark gas detectors are affordable, solid and robust devices designed for monitoring the level of toxic gases found in enclosed carpark and loading dock environments.

The iQguard carpark sensors are small light weight devices and easy to maintain and servcie. Operation is simple, and they are IP54 rated.

Used in conjunction with a controller, the iQguard carpark sensors run with variable speed drives on exhaust fans to reduce excess power usage.
