Sensorcon Inspector 2 CO Carbon Monoxide Monitor with Visual and Audible Alerts, Waterproof and Two Year Warranty

my son is a long haul trucker which means he lives in his truck. The device is monitoring cabin air quality and alerted him to co2 being suck into the cabin really saved his life.

I have a small property that has a small backyard. I use this outside buy due to winds, I worried that the exhaust could find its way into the house or garage.Depending on where I place the generator, exhaust is an issue. I hang this up in the room of concern to monitor CO. It is NOT an alarm and I knew that. I want to know what the constant exposure is and this unit does it.When levels above XX level are reached (warning but not dangerous levels) it start to beep and red lights flash to let you know there is higher levels of CO. I have separate alarms for the house.I use a fan to disperse the CO into the air and that eliminates all or most CO depending on location.

I wear this model (and last generation) every workday for 4 years now. I do HVAC and it assists with fast zeroing of combustion analyzers, peace of mind when walking into unknown environments, and higher equipment sales. It is a valuable tool. I use it in conjunction with other tools and industry methods, to make me a better technician.

Was worried about turning it on/off for use in an airplane cockpit, but now we just leave it on and it's gone many months without being turned off and it's still on the original battery.

Always on during use enable you to see exact CO levels.Must hold on 3-seconds to turn off.
