Carbon Monoxide Detectors for Home/Hotel/RV with Temperature Humidity Sensor and Alarm

The KH Alert AC-Plug in CO Detector with Temperature and Humidity Display is suitable for all places where carbon monoxide could potentially be produced, such as your home's kitchen, bedroom, bathroom, or even in a hotel. It is also useful when enjoying a barbecue, using charcoal to keep warm, or placing it in your parking garage.

This 3-in-1 carbon monoxide detector features a temperature and humidity display, allowing you to stay informed about the environmental conditions in a timely manner. With its plug-and-play design, the device can be directly plugged into a power outlet, eliminating the need for power cords and offering a simple, hassle-free installation.

The detector provides fast response to carbon monoxide, temperature, and humidity levels, keeping you well-informed about potential air quality issues so you can quickly identify and address the problem.

The package includes 1 carbon monoxide detector, 1 manual, and 1 protective cotton plug. Simply plug the device into a power outlet, and the carbon monoxide alarm will begin its countdown warm-up period. Once the warm-up is complete, the green light will indicate that the detector has entered its normal working condition.

To test the alarm, press the SELF-TEST button. If the alarm sounds, it means the carbon monoxide detector is functioning properly and can be used. If the alarm does not sound, it indicates that the detector is damaged and should not be used.

Under normal operating conditions, you can use a lit cigarette to aim the gas at the sensor position. If the device displays a digital reading or activates an audible and visual alarm, it confirms that the carbon monoxide detector is working correctly.

The KH Alert CO Detector operates on AC 110-220V power and can detect carbon monoxide levels ranging from 0 to 999 ppm. The alarm will sound when the concentration reaches 150 ppm, and the display will show readings up to 100 ppm.

The temperature display range is 1-176°F, and the humidity display range is 0-99%. The sensor has a lifespan of 3 years.
