Product Description

Even with a presumed presence of CO, (Carbon Monoxide), a measurement of 0 ppm is not uncommon. Designed for industrial and commercial applications, the Sensorcon INDUSTRIAL PRO displays carbon monoxide (CO) gas concentrations as low as 1 ppm and features visual, audible and vibrating alerts, user-adjustable alerts levels from 1 ppm, and Intrinsically Safe certification. Even with a presumed presence of CO, (Carbon Monoxide), a measurement of 0ppm is not uncommon. An easy to read LCD displays CO up to 1,999 ppm in 1 ppm increments with +/- 10%, ( or +/- 2 ppm), accuracy. (NOTE: Whichever value is higher) Use as a personal monitor, ambient air monitor, or to inspect combustion equipment using the optional pump and probe. Unlike other similarly priced CO monitors, Sensorcon units are designed for long-term ownership. Replacement battery and calibration services are available. Manufacturer warranty is one year.

All Sensorcon units are low-level monitors which display carbon monoxide levels as low as 1 ppm. This particular model allows the user to set low and high level alert limits, and includes a 24-hour TWA (time weighted average) memory feature.

I bought this so I can detect how much exhaust is coming inside my suv especially when I accelerate. When I drove my car the other day without speeding, the reading was between 1 to 3ppm. Then I took it to my place of work where the exhaust fumes from machines kinda linger in the office and the reading that I got varies from 3ppm and it even went as high as 28 ppm. The first device that I bought was an unrealiable CO blue/red led car charger, the second device only worked when I put it near the source of the CO (exhaust or smoke), the reading was inaccurate.This device it the third one that I’ve owned and it is very responsive and the reading is very accurate. It was the best so far and it’s made in the USA, so I guess third time’s a charm.

Purchased the "Inspector Pro". Paided shipping. FedEx calculated the tax and duties for my province of Ontario. Great product. I will be using this every day at work. I purchased it January 22, 2018. August 14, 2018 I contacted seller. The manufacturer, went to there website and called customer service. Spoke with Steve. Told him about water in the unit. Water is under the screen. He guided me through the sensorcon website. I'll be sending it in and either repaired or replaced.
