Application of 7701 AZ CO Detector:
CO levels and its effect
The 7701 AZ Carbon Monoxide Alarm Detector could measure Carbon Monoxide concentration in ppm. It has the big LCD to display the current CO value in the closed space, car, hospital, factory or other environmental situation. Users can set and adjust CO Concentration alarm for different purposes.
The 7701 AZ pocket digital CO tester has the back light function, which could let user to operate in the dark area easily. It could be calibrate by user.
The 7701 AZ pocket digital CO tester was being designed and manufactured by AZ Instrument, a well experienced manufacturer for Environmental Measuring Instrument.
