33% OffMain highlights- 【Intimate Brightness Design】When you feel that keeping the high-definition screen on is very power-consuming, you can choose to press the "Brightness" button to adjust the brightness condition. When you choose to turn off the screen brightness, the product will continue to monitor and the indicator light will remind you every 5 seconds to inform you that the product is under normal monitoring.
- 【High-precision Comprehensive Detector】 The detection range is 0-999PPM, and the accuracy is ±5%. It can also be used as an thermometer with a temperature range of 14℉ ~ 122℉ and an accuracy ±3%; it can also be used as a hygrometer with a humidity range of 5% ~ 95%RH and an accuracy ±5% RH.
- 【Advanced Sensor】When exposed to carbon monoxide it generates an electric current immediately, meaning it responds faster and more accurately than traditional sensor, and is less susceptible to being affected by other gases. Please note that when there is no carbon monoxide gas in the air, it is normal for the product to display a reading of 000PPM.
- 【A comprehensive Portable CO Detector Plug in Design for Travel】Carbon monoxide is hazardous. When the concentration of carbon monoxide in the air exceeds safe limits, it can cause physical harm and endanger life. Compatible with 110V to 220V AC power outlets, this plug-in carbon monoxide detector is a portable device specifically designed for travel—helping to ensure greater peace of mind during your adventures.
- 【2.1-inch High-definition Display】 Not only can the carbon monoxide concentration value be intuitively viewed on the 2.1-inch high-definition display, but also the temperature and humidity conditions of daily concern can be clearly seen.
- Note: This device only supports the detection of carbon monoxide, temperature, and humidity in the air. It does not support the detection of carbon dioxide, smoke, or flammable gases such as methane and propane.
