Tlily - PTH-10DH Carbon Monoxide Detector co Air Quality Portable Horizon Monitor hd led Screen usb Charging for Indoor Travel

The portable PTH-10DH carbon monoxide detector can monitor the current CO concentration, temperature and humidity in the air in real time. Also supports altitude measurement and horizon measurement. Equipped with high-precision sensors, the detectable carbon monoxide concentration range is 0~500PPM, the temperature range is 32~122℉(±2.7℉)/0~50℃(±1.5℃), and the humidity range is 20~80%RH (±5 %RH). The carbon monoxide alarm can display 3-level 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 sound an alarm when it reaches 50PPM. Altitude measurement: When hiking outdoors and climbing mountains, you need to pay attention to sea level data. When the fluctuation is 50m, you should be aware of possible disaster weather (such as typhoons). Built-in 1000mAh lithium battery, power supply. Support QC2.0, PD3.0, AFC, USB C UFP (BC1.2
