Air Quality
CO Detector
Sensor for measuring carbon monoxide (CO)
concentration
SensiCO PX 300 is a reliable sensor for measuring
carbon monoxide (CO) concentration in locations, such
as car parks and garages.
As CO, a dangerous poisonous gas, has no smell, taste
or color, it is important to install SensiCO PX300, as a
total protection from CO poisoning.
When CO concentration exceeds 50 PPM, a signal to
the ventilation system is activated and an alarm is sent
to the car park management/ control. SensiCO PX 300
may be connected to a self-control system or to the
B.M.S. (Building Management System), using its analog
output.
