LSENLTY Carbon Monoxide Detectors Support 3 Years Standby Time for Home and Travel, 4 Pack-CDR-817

• Portable Carbon Monoxide Detector: compact size, dimension 8.1*5*2.7cm, weight 80g, with mesh bag (the mesh bag is at the bottom of the box, don't forget to open the plastic layer inside the package), adhesive lining and fixing screws.
• CO Concentration Range: The detection range of the co detector is 0-999PM. Updated every 3 seconds. If the concentration exceeds 50PPM, the product will sound an alarm within 60-90 minutes. If the concentration exceeds 100PPM, the product will sound an alarm within 10-40 minutes. If the concentration exceeds 300 ppm, the product will sound an alarm within 3 minutes.
• 3-Year Standby Time: The carbon monoxide detector is equipped with a battery that has a battery life of up to 3 years.
• Indicator Light Means: The green indicator light flashes to indicate that the product is continuously detecting the carbon monoxide concentration in the surrounding environment and is updating the value every 3 seconds. A red indicator light indicates that the product's battery is low or malfunctioning. When a fault signal is signaled, Err will be displayed on the screen and a beep will sound. Indicates that the device is faulty or the sensor has reached the end of its lifespan.
• Memory function: The carbon monoxide detector continuously monitors. When you press the button, the peak CO concentration for this period will be displayed with a beep sound.

• Support 500 Hours Standby: LSENLTY portable carbon monoxide detector's standby time can last up to 500 hours. When the detector is plugged in, the device's screen backlight will remain on. When the detector is not plugged in, the device will automatically turn off the screen backlight without any operation after 5 minutes.
• More Accurate CO Detector: carbon monoxide measurement range is 0-1000PPM, accuracy is ±5PPM. The temperature measurement range is 5℉ ~ 122℉, the accuracy is ±2.7℉, the Humidity measurement range is 0 ~ 99%, and the accuracy is ±5%.
• Convenient Design: Portable and compact design (dimensions: 0.3*6.6*1.4 inches), equipped with a lanyard design.
• Alarm Function: When the value exceeds 50PPM, an alarm will be issued. As the PPM value increases, the frequency of the alarm will increase. If you need to turn off the alarm sound, you can short-press the button to turn off the alarm sound. But for security design, if the CO concentration continues to exceed 50 PPM, even when turning off the alarm sound, the alarm sound will continue after 15 seconds.
• 10-Year Sensor Lifespan: Enjoy greater safety and peace of mind thanks to import CO sensor's 10-year lifespan.

• 120 hours standby time: Built-in 1000mAh large-capacity rechargeable battery. Equipped with a Type C charging port, it can use the fast charging protocol. It takes only 90 minutes to fully charge the carbon monoxide detector. The standby time after full charging reaches 120 hours.
• Portable design: Portable and compact shape specially designed for outdoor and home(size: 2.9 x 2.7 x 1.1inch/ weight: 0.26lb) with lanyard and magnet design.
• 3 in 1 Portable Carbon Monoxide Detector: The carbon monoxide measurement range is 0-500PPM with an accuracy of ±5PPM. The temperature measurement range is -10°C to 50°C (14°C to 122°F) with an accuracy of ±2°F, and the humidity measurement range is 0-95% with an accuracy of ±5%.
• Alarm Function: Compared with traditional carbon monoxide detectors, this upgraded portable carbon monoxide detector allows you to clearly see the carbon monoxide concentration value and clear concentration range from the high-resolution screen.
