Support working when charging.Package includes 1x type-c USB cable, compatible with all chargers or power bank.(Charger not included) 【Screen display CO caution】[CO ppm: 0-99, good shows with green scale mark ]. [CO ppm: 100-149, warning shows with yellow scale mark]. [CO ppm: 150-500, Bad shows with red scale mark].we can custom the trill alert CO value from setting button, Factory trill alert Default: 100ppm. 【How to test it ?】 Carbon monoxide is generated in incomplete combustion and dense smoke. We can take it close to a cigarette or burning paper that produces thick smoke. The CO concentration will change and show on the screen. Don't test it by car exhaust or airy place, too low CO consentration can't not trigger sensor to work., Weight: 0.73 Pounds, Manufacturer: Protech International Group CO.,LTD.
