## Description

The ET110 CO Detector is an easy-to-use meter that detects and measures concentration levels of carbon monoxide (ppm) and temperature (Fahrenheit/Celsius), making it the perfect choice for HVAC professionals. Features backlit LCD screen, warning indicator light, audible and visual alarms and multiple function buttons. Includes carrying pouch and 4 x AAA batteries. For more than 160 years, Klein Tools has manufactured premium-quality, professional-grade hand tools that deliver the performance, durability and precision needed to get the job done right. Our family of engineers, workers and craftsman continue to put six generations of expertise into every tool we create by using only the highest quality materials, superior workmanship, and keeping manufacturing as close to home as we can. Klein isn't just the name of our company, it's also our family name. And since we're an American company that's family-owned and family-run, you know you can count on us to be here tomorrow. Klein Tools doesn't just make great products, we make great products that stand up to the demands of the professionals who use them every day ... Since 1857.

Review: Appears to work as expected. Reports zero when in clear air. Reports over 300PPM when placed about 4ft from UTV exhaust (it's a 20 year old gas engine). The response time was 2-3 seconds 4ft from gas engine exhaust and readings zoomed over 300ppm and I moved away. Real world quick test appears to work. I tested our home air ducts in several places with this meter and all of them read 0. We wanted to put a number to CO ppm in addition to the smoke detectors with CO detection which always show OK without any numeric value. Having a good quality meter seems like a wise idea if you have natural gas or propane heating. I am happy with the unit after one use. Note: If you are a home owner and not likely to use the meter very often, consider removing the AAA batteries after each use so there is no chance of a battery leaking into the meter.
