Model KGA5 CO sensor is intrinsically
safety product, used for measuring the CO content of the air
of mine underground continuously.
The sensor is an intelligent detection instrument with remote
control for calibration and it has the advantages of high
accuracy, stable reliability and flexible use. It can be used
singly or with all mine-used safety monitoring and control
systems.
