Ulisem Carbon Monoxide Detector, Carbon Monoxide Detector with Digital Display and Audible Alarm, Battery Powered (No Batteries Included)

General Description Carbon monoxide detector with digital display and audible alarm, powered by AA batteries (not included). It is designed to quickly detect carbon monoxide gas using a high-precision electrochemical sensor. The device is equipped with an LCD screen for easy reading of real-time concentration values (ppm) and emits audible and visual alarms when the concentration exceeds a certain threshold. Technical Specifications Sensor Type: Electrochemical Power Supply: AA batteries (not included) Display: LCD screen Detectable Concentration: From 30 ppm Operation To use the detector, insert AA batteries and it will turn on automatically. The screen will turn off after startup, which is normal. When the carbon monoxide concentration exceeds 30 ppm, the screen will illuminate to display the PPM value. In case of a high concentration, an audible alarm will sound and a red light will flash, allowing for a quick reaction to ensure safety. Other Information
