The rechargeable oxygen monitor also features a flashlight, SD card data storage, and a convenient lanyard, making it not only suitable for indoor air quality monitoring but also an ideal travel companion.\u003c\/li\u003e\n\u003cli\u003e【High-Precision Sensors】The O2 monitoring system uses a high-sensitivity DDS sensor imported from the UK, boasting excellent stability and rapid response. The CO monitoring system is equipped with a professional electrochemical sensor, exhibiting extremely high selectivity for CO and capable of sensitively detecting low-concentration leaks. The CO2 monitoring system features an NDIR infrared sensor, offering strong anti-interference capabilities and ensuring long-term stable CO2 measurements.\u003c\/li\u003e\n\u003cli\u003e【Dual Audible \u0026amp; Visual Alarm】The oxygen detector is equipped with a 3.27\" HD color LCD screen. When any indicator reaches the alarm threshold, the corresponding value on the screen will immediately flash prominently, accompanied by a loud alarm sound. When the alarm sounds, you can choose to temporarily mute it for 5 minutes; if the risk persists, the alarm sound will automatically resume. Alternatively, you can choose to permanently disable the alarm sound, leaving only the visual flashing.\u003c\/li\u003e\n\u003cli\u003e【2500mAh Large Battery】This oxygen monitor features a built-in 2500mAh rechargeable lithium battery, coupled with an automatic sleep mode (the screen automatically turns off after 1 minute of inactivity), effectively extending usage time. The inclusion of a universal Type-C interface makes charging more convenient and efficient. Even when charging in sleep mode, the screen backlight remains on, allowing the device to continue operating normally and enabling real-time monitoring while charging.\u003c\/li\u003e\n\u003cli\u003e【Calibration Mode】Upon power-on, the oxygen monitor will automatically enter a 1-minute countdown warm-up phase. For oxygen levels, the oxygen detector provides dual automatic calibration values of 20.9% and 0%. Manual calibration is available for carbon dioxide, temperature, and humidity. For safety reasons, carbon monoxide calibration is prohibited.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"SQECH","offers":[{"title":"Default Title","offer_id":46755431284925,"sku":"B0FDQQYTBL","price":123.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0755\/9344\/9661\/files\/61cO6exLTuL._SX522.jpg?v=1778236851","url":"https:\/\/smarthomevaluehub.com\/products\/b0fdqqytbl","provider":"SmartHomeValueHub","version":"1.0","type":"link"}
