LSENLTY Carbon Monoxide Detector, NDIR Type, Portable Carbon Monoxide Detector, CO Leak Checker, 0-500 PPM Measurement Range, Rechargeable, Built-in L

Warm Tip: If there is no carbon monoxide gas in the surrounding environment, the product will display a normal reading of 0000 ppm. 3-in-1 CO Detector: Unlike other carbon monoxide detectors that can only be installed on the ceiling, the LSENLTY carbon monoxide detector can be hung on a wall or placed on a table. Equipped with three air indicators for carbon monoxide, temperature, and humidity, it protects your family. Easy to Read: Carbon monoxide concentration detection range: 0-500 ppm. The LSENLTY carbon monoxide detector features a three-segment color display for clear and easy reading. Green/Normal: 0-99 ppm, Yellow/Warning: 100-149 ppm, Red/Danger: 150-500 ppm. High-Precision Carbon Monoxide Detector: High-precision detection technology includes a carbon monoxide measurement range of 0-500 ppm (±10 ppm), a temperature measurement range of 0°C to 50°C (±1.5°C), and a humidity measurement range of 20-80% RH (±5% RH). Notification Function: The LSENLTY carbon monoxide detector defaults to notifying you when the level exceeds 150PPM. At the same time, you can double-click the "O" button to customize the CO alarm value and intensity alarm range. When the intensity exceeds the range, the system will automatically send a notification. If you want to turn off the alarm sound, press and hold the "+" key to switch the buzzer sound.
