- 【HIGH-PRECISION 4-IN-1 CO DETECTOR】The portable 4-in-1 carbon monoxide detector can monitor the current CO, CO2, temperature and humidity in the air in real time. Equipped with a high-precision sensor (10-year life), the detectable CO concentration range is 0~1000PPM (±10%), the CO2 concentration range is 400~5000PPM [± (50PPM + 5%)], and the temperature range is 14~122℉ (±2.7℉) / -10~50℃ (±1.5℃), humidity range is 0~95%RH (±5%RH). The data is accurate without delay and monitored in real time.
- 【CO LIGHT INDICATION & CUSTOMIZED ALARM VALUE】The carbon monoxide monitor can present 3-stage light indication based on CO concentration. 0~99PPM (green flashing=safe), 100~149PPM (yellow flashing=warning), 150~1000PPM (red flashing=danger). By default, the CO monitor will sound an alarm when it reaches 150PPM. You can double-click the "function button" to customize the CO concentration alarm threshold. Note: The device must be in the "CO" interface before entering CO custom settings.
- 【CO2 LIGHT INDICATION & CUSTOMIZED ALARM VALUE】The carbon dioxide monitor can present a 3-stage light indication according to the CO2 concentration. 400~699PPM (green flashing=safe), 700~1499PPM (yellow flashing=warning), 1500~5000PPM (red flashing=danger). By default, the audio alarm sounds when it reaches 1500PPM. You can double-click the "Function Button" to customize the CO2 concentration alarm threshold. Note: The device must be in the "CO₂" interface before entering the CO2 custom setting.
- 【LARGE CAPACITY BATTERY & FAST CHARGING】The MINI 4-in-1 CO detector has a built-in 1000mAh lithium battery for long-lasting power. Support QC2.0, PD3.0, AFC, USB C UFP (BC1.2 DCP CDP SDP) and other common fast charging protocols 10~65W charging. When the CO detector is not operated for 5 minutes, it will automatically turn on the energy saving mode (the brightness of the screen will be reduced), and you can click the "function button" to turn on the backlight.
- 【OUTDOOR LANYARD & MAGNETIC SUCTION】The bottom of the CO CO2 air quality monitor can be placed freely, you can put it on the table in the living room, kitchen, bedroom, etc. And it is equipped with a special outdoor lanyard, which is convenient for you to carry and use in outdoor activities such as travel, camping, picnic, and adventure.
