<p>The portable carbon monoxide detector can monitor the current CO concentration, temperature and humidity in the air in real time.</p> <p>Equipped with high-precision sensors, the detectable carbon monoxide concentration range is 0~1000PPM(10%), the temperature range is 14F~122F( 2.7F), and the humidity range is 0~95%RH(5%).</p> <p>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), 100~1000ppm (red area flashing = danger). By default, the CO alarm will sound an alarm when it reaches 50PPM.</p> <p>Built-in 1000mAh lithium battery, power supply. Support QC2.0, PD3.0, , USB C UFP (BC1.2 DCP ) and other common fast charging protocols 10~65W charging.</p> <p>Equipped with a special outdoor lanyard, it is easy to carry, suitable for outdoor activities such as travel, camping, picnic, and adventure. There is also a magnetic feature on the back of the CO monitor, allowing it to be attached to metal areas such as appliances or cars.</p> <p>Carbon Monoxide: 0~1000 ppm(10%)</p> <p>CO Sound Alarm Range: default, 50 ppm</p> <p>Temperature:-10C~50C(1.5C)\/14F~122F( 2.7F)</p> <p>Humidity: 0%~95% RH (5%)</p> <p>Battery: Built-in polymer lithium-ion battery (3.7V, 1000mAh)</p> <p>Input: Type-C, DC 5V~DC 24V (Max), support the fast charging</p> <p>protocol with a power of 10 ~ 65W</p> <p>Fast charging protocol: QC2.0, PD3.0, , USB C UFP (BC1.2 DCP ) and other common fast charging protocols (1C) charging</p> <p>Different batches may have different appearances, but will not affect the use</p> <p>Storage Temperature:-20C~60C\/-4F~140F</p> <p>Colour:orange</p> <p>Material:ABS</p> <p>Package Contents:</p> <p>1 x Mini Carbon Monoxide Detector</p> <p>1 x USB cable</p> <p>1 x Lanyard (random colors, don't accept the specified color)</p> <p>Only the above package content, other products are not included.</p> <p>Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
