LogiLink indoor air quality monitor with CO2 alarmMonitor your air quality wherever you areEasy-to-use, real-time monitoring of air quality, temperature, and humidity in the environment you're in. The easy-to-read display simplifies reading in an intuitive way. The compact size with built-in lithium battery is made for travel. Perfect for the home, schools, offices, camping areas and anywhere where high levels of carbon dioxide are generated. Easy to read, Easy to controlLarge LCD display to monitor CO2 concentration (5000 ppm range), temperature and humidity at the same time. Avoid home or health problems as it tips you off on potential sources of CO2. Highly accurate and consistentThis detector with a non-dispersive infrared sensor (NDIR sensor) is a simple spectroscopic sensor that is often used as a gas detector. Easily track CO2 for improved health, productivity, and overall well-being. Always stay informedGet audio and visual alerts when concentration levels go above 1600 ppm. The visual alarm LED indicator shows real-time air quality levels (green=good, yellow=caution, red=poor). All dayWith a built-in 2000 mAh battery, it provides a runtime of up to 16 hours and can be easily charged via micro-USB. Designed to take with youComes with a stand as well as a magnetic wall mount; Simply attach it to the wall or place it on the desk/floor.
