Two Wiltec CO Detectors with Display – Reliable Protection Against Carbon Monoxide: Carbon monoxide (CO) is a colorless, odorless, and tasteless gas that is produced during the incomplete combustion of fuels. It can be life-threatening as it accumulates unnoticed and blocks the body's oxygen intake. A reliable carbon monoxide detector is therefore essential for safety in residential or workspaces. The Wiltec CO Detector detects even low concentrations and triggers an alarm in a timely manner when dangerous levels are reached – providing effective protection around the clock. CO Guardian Set - Precise Measurement and Reliable Alarm: The set includes two Wiltec CO detectors that measure carbon monoxide concentrations in the range of 10 to 550 ppm. Thanks to the digital display, you can always keep an eye on the current value. The display is particularly accurate, with the following deviations: - 30 ppm ± 10 ppm - 50 ppm ± 10 ppm - 100 ppm ± 15 % - 300 ppm ± 15 %. As soon as a critical value is reached, an acoustic alarm sounds at over 85 dB (measured at a distance of 3 m), reliably alerting you to the danger. The CO alarm is therefore excellent for early warning against carbon monoxide. Flexible Application Options Thanks to Freestanding Design: The Wiltec CO alarm is designed to be freestanding, allowing for flexible placement in any room. Whether in the living room, bedroom, basement, or workshop – this gas detector can be set up without drilling or mounting. Its compact dimensions enable discreet integration into any environment. CO Detector - Long-lasting Operation with Replaceable Batteries: The power supply is provided by two included AA LR6 batteries per alarm. These offer a lifespan of up to 3 years and can be easily replaced when needed. The gas alarm detector is therefore low-maintenance and independent of the power grid – ideal for use in holiday homes or mobile accommodations.
