OKEAH Smoke and Carbon Monoxide Detector,Replaceable Battery-Operated CO Alarm with LCD Display,YJ-901 - -

Description

By triggering the button, the smoke concentration and carbon monoxide concentration in the environment are displayed at any time, accompanied by the regular flashing of the LED indicator, to actively inform you of the alarm and the safety status of the environment. The operation is simple and easy to understand. It integrates a highly sensitive photoelectric sensor and a highly stable electrochemical carbon monoxide sensor at the same time. Whether the smoke or the carbon monoxide concentration in the environment exceeds a certain index, it will send out an alarm to remind you to stay away from danger. Depending on the quality of the battery, the alarm battery needs to be replaced every 1-3 years. As we all know, the battery life will be shortened by the influence of the environment, especially in the extremely cold environment. The detachable way can ensure that when the battery fails,you only need to replace the battery instead of throwing away the alarm.
