【5-in-1 Air Oxygen Monitor】This rechargeable oxygen monitor is a good assistant to protect our health and safety. It can not only be used indoors, the oxygen detector is also an outdoor artifact for travelers. The 5-in-1 multifunctional oxygen meter can detect CO concentration range is 0-500PPM, O2 concentration range is 0-30%VOL, temperature range is 32℉-122℉, humidity range is 0-95%RH, and atmospheric pressure range is 300-1100hPa.（Note: The SAQ-04 model does not measure CO2！）
【High Precision Sensors】This 2.0 version oxygen monitor uses a British-imported DDS sensor for its oxygen sensor, which is not only highly sensitive but also accurately captures subtle changes in the oxygen content in the air. The CO sensor is an electrochemical sensor that can precisely lock onto CO, providing a safe barrier for you in a colorless and odorless environment.
【Audio & Visual Alarm】The oxygen detector not only provides an audible alarm, but also a visual reminder so that you can protect your safety in time. When the CO value of the oxygen monitor reaches 51-200PPM, the audio alarm sounds every 10 seconds and the CO icon starts flashing; when it reaches 201-500PPM, the audio alarm will continue to beep. When the oxygen meter detects that the O2 concentration is lower than 19.5%VOL or higher than 23.5%VOL, the sound alarm starts and the O2 icon flashes.
【Long Battery Life】The oxygen monitor features a built-in 1500mAh lithium battery, supports Type-C charging, and boasts long battery life. Furthermore, it has an automatic sleep mode to effectively save power. After one minute of inactivity, the oxygen detector's display will automatically turn off and enter sleep mode; pressing any button will wake it up. While charging in sleep mode, the display remains backlit, allowing for real-time monitoring of various indicators while charging continues.
【Portable & Drop-proof】The air oxygen monitor is equipped with a dedicated outdoor lanyard, and its compact design makes it easy for you to carry and use during travel, camping, picnics, adventures and other outdoor activities. The portable oxygen detector is made of aluminum and has a porous design, which is not only anti-fall and corrosion-resistant, but also heat-dissipating and ventilated, making it more worry-free for you to use.
【Calibration Mode】After power-on, the oxygen detector will automatically preheat, and the oxygen value will flash continuously. The oxygen monitor provides two automatic calibration values: 20.9% and 0%. Temperature, humidity, and air pressure can be manually calibrated. For safety reasons, carbon monoxide calibration is prohibited.
