Feature:1. High Precise Sensor: Adopts high precise electrochemical sensor, quick response, high accurate measurement, with the measurement ranges of 0-1000ppm.2. Digital LCD Display: High bright screen with backlight, the carbon monoxide concentration, temperature, and power can be seen at a glance. The backlight color will switch according to the detection situation, and Fahrenheit / Celsius can be switched.3. Sound \u0026 Light Alarm: Two alarm levels (high and low alarm) design, when the concentration is lower than the low alarm value, a low slow beeping sound and motor vibrations alarm will be issued; when the concentration is higher than the high alarm value, a fierce beeping sound, motor vibrations alarm will be issued and the backlight of display turns to red for warning.4. Parameter Setting: Support auto power off (APO) setting, low limit alarm (LAL) setting, and high limit alarm (HAL) setting. Auto shutdown time default 10 minutes(can be set closed). Alarm value setting ranges of 0-1000ppm.5. Wide Applications: It can detect a variety of gases, such as natural gases, gases, liquefied gases, fuel oil, coal, etc. incomplete combustion to produce carbon monoxide concentration detection.6. Application Scenario: Suitable for evaporate heating room, garage confined space, gases water heating device, gases for cooking, etc.Specification:This carbonic oxide tester adopts high precise electrochemical sensor, quick response and high accurate, with the measurement ranges of 0-1000ppm.
