Specifications:

• PRECISION CO METER:Handheld carbon monoxide meter with sensitive professional electrochemical sensor can detect CO range from 0~1000PPM and temperature range from 32~122℉ / 0~50℃. With auto-calibration function, it can help you detect carbon monoxide gas concentration timely and accurately, reduce the risk of carbon monoxide poisoning, and protect the life and property of you and your family.
• SOUND AND LIGHT ALARM & SELF-SET ALARM VALUE:Carbon monoxide detector adopts visual and audible alarm, alarm value can be set freely (preset 24PPM). When the detected CO gas concentration reaches the alarm threshold, the CO detector will emit a beep sound and screen flashing alarm to remind you of the presence of carbon monoxide gas around you, so that you can detect the danger in time to protect yourself. Click the “ON/OFF button” to turn the beeping sound on or off.
• 4 TEST MODES:Carbon monoxide tester has 4 test modes, namely: real-time data, data hold, maximum value, minimum value.The power-on warm-up time of the CO tester is 120 seconds, and you can press the “ON/OFF” button to enter the test mode directly. In the test mode, just click the “MODE” button to switch between the four test modes easily. You can adjust the appropriate mode according to your usage or working environment.
• PRACTICAL DESIGN:Portable carbon monoxide detector is small in size and light in weight, easy to use with one hand. With back clip design on the back, it is very easy to work and carry.
