Inspector 2 Portable Carbon Monoxide Detector with Visual & Audio Alerts – Professional-Grade Digital CO Detector for Industrial & Commercial Applications

I like having this for travel. Every time I hear of some tragic loss of life due to carbon monoxide during travel, I am reminded to bring this with me when I travel.

The item, once it finally did arrive, is as expected. Great, responsive customer service although there was a problem with the US Postal Service.

Got it and it didn’t work at all stayed at 0 even when I was right next to a back up generator

Day 1 but so far so good. Seems very accurate. Picked up 7ppm CO from a match and also picked up 1 ppm in garage after I pulled the car in and turned it off. I previously bought a different brand and it wasn’t accurate at all. This one is worth the extra money.

Good unit for the price, it is working perfectly, I test it every other month with bump gas to be sure it stays accurate. Expect Ineed to swap sensor at some point, but lets see how long it keeps up.I did see a comment mentioning a false alarm. Do you homework and be aware there is always cross-sensitivity with other gases like H2 and NOx and some solvents. Even a sharpie can set it off. (Even some HVAC combustion analyzers have this issue) If you want to avoid this you need a unit that will cost a multitude of the price.Beter a false alarm, as no alarm at all 😎😎Stsy safe out there people

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 bought this on the insistence of my HVAC man after my furnace heat exchanger had failed. The Sensorco¿n unit far surpasses home user CO detectors for sensitivity. It will read as low as 1 ppm and can be set to alarm as low as 5 ppm. It will detect the low level of CO leaking from my garage into the living space as I back the car out (garage is attached to the basement where the detector is located). Normally it reads 0. I have an unvented gas heater in my office, and I am confident that it puts out no CO with the Sensorcon monitoring the air. Great device!

False Alarm.I'm not certain what this CO meter is reading, but it is something other than Carbon Monoxide. We had been alarmed by CO levels coming from the air vents reading at 14ppm. We checked our second furnace and the air coming from the vents was Zero. So naturally we called our HVAC only to learn that his meter was reading Zero and 12 from the exhaust vents. Someone had a defective meter and certainly it wasn't me because this is only a week old and a replacement. So we called the Gas company and they sent the first department with them - the FD arrived first and their equipment measured Zero, the gas company was soon to follow and they went through an extensive CO tests and even the exhaust vents measured Zero when the heating guy measured 12 PPM.The unit is going back and it's time to do a bit more research.One last thing, the FD was using Sensorcon before they replaced them last year with vacuum sniffing detectors.Very disappointed that these might have have gone through a quality control test before shipping, it's an expensive unit, but certainly not a $4,000 unit either, but it should have worked correctly.Maybe this one is measuring dust in the air, who knows. Next one I buy will be certified by the company. I don't believe this one is certified.
