Portable Carbon Monoxide Detector Temp/Humi/CO Sensor Alarm Outdoor/Indoor

About this item：

• 【High-precision 3-in-1 Co Detector】The portable 3-in-1 carbon monoxide detector can monitor the current CO concentration, temp and humidity in the air in real time. Equipped with a high-precision sensor, the detectable CO concentration range is 0~500PPM, the temperature range is 14~122℉ (±2.7℉) / -10~50℃ (±1.5℃), and the humidity range is 0~95%RH (±5%RH).The data is refreshed every 2 seconds and displayed on the color HD screen,allowing you to always understand the ambient air quality.
• 【Long-Lasting】Our portable detector is designed with your mobility in mind, offering a robust 1000mAh battery that provides up to 120 hours of standby time, and supports type-C charging, making it perfect for travel, RV use, and camping trips.
• 【3 Light Indications & Custom Alarm Values】The carbon monoxide alarm can present 3-stage light indications according to the CO concentration in the air. 0~49PPM (green area flashing=safe), 50~99PPM (yellow area flashing=warning), 100~500ppm (red area flashing=danger). By default, the CO alarm will sound an alarm when it reaches 50PPM. You can double-click the "function key" to customize the CO concentration alarm threshold.And the customizable CO value range is: 25-125ppm. 
• 【Portable design with lanyard & Magnet】Our mini CO detectors are designed to be portable and convenient. With dimensions of 2.9x2.7x1.2 inches, they are compact and easy to carry. The strong lanyard allows you to hang it anywhere you want, such as on the wall, backpack, tent inside, car, RV, and more. Additionally, the built-in magnet allows you to easily attach it to metal items. The flat bottom of the detector enables you to conveniently place it on a table.
• 【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.
