Tuya Wifi Portable Electrochemical Sensor CO Tester LCD Screen Carbon Monoxide Detector with Sound Lihgt Alarm and Low Battery Reminder Function ( Item#: E25222 )

This CO tester adopts a low power consumption electrochemical sensor, fast response, highly precise measurement, and more accuracy. Real-time detection with an intelligent alarm, quickly identifies and finds the gases leaks, when the carbon monoxide concentration reaches the set value, the device immediately sends a high decibel alarm. Large LCD screen, you can see the detection value clearly at a glance. With a low battery reminder function. Suitable for use in situations where carbon monoxide gases, mists, and carbon monoxide residues are present. Carry out carbon monoxide gases detection and find the source of leakage. 

Features:
Compact and Beautiful: Compact body, lightweight and portable, with a simple and fashionable appearance, will not occupy too much installation space.
Fine Workmanship Design: The housing is made of high-strength ABS material, which is drop and wear-resistant and has a long service lifespan.
Clear-definition LCD Display: Large digital LCD screen with clear definition, you can see the detection value clearly at a glance. With a low battery reminder function.
High-precise Sensor: Adopts high accurate electrochemical sensors, fast response, highly precise measurement, and more accurate. With high sensitivity, superior interference resistance ability, and stable working performance.
Intelligent Detection & Alarm: Real-time detection with an intelligent alarm, quickly identifies and finds the gases leaks, when the carbon monoxide concentration reaches the set value, the device immediately sends a high decibel alarm. Sound and light alarms are more accurate and reliable. 
Multifunctional Design: With fault self-test, faulty warning, and low battery warning functions.
Cellphone Tuya APP Control: Search for Tuya APP in the application program, the device will enter the pairing state after the firsttime opening, and you can view the specific data on the APP after completing the connection. (Because it takes time to upload data, it is normal for the APP data to deviate from the real-time data of the detector.) Whether you are on vacation, at work or home, you can enjoy the convenience of the mobilephone APP. 
Strong Heat Dissipation: Hundreds of ventilation holes reserved on the housing not only accelerate the convection between the air and the machine, thereby realizing effective detection but also provide a fine heat dissipation effect.
Easy to Use & Install: Large test button for easy operation. It can be wall-mounted for convenience and ease of installation.
Wide Applications: Suitable for use in situations where carbon monoxide gases, mists, and carbon monoxide residues are present. Carry out carbon monoxide gases detection and find the source of leakage. Suitable for home, kitchen, car, restaurant, indoor places, and so on.
