TASI-651 carbon monoxide Tester can detect low concentrations of carbon monoxide. The CO concentration measurement range is 0~1000ppm. The presence of carbon monoxide in the air can also be detected. The principle of the sensor of this carbon monoxide meter is that it is reduced by vaporization and does not consume any chemicals. The duration of use depends on the environment to which it is exposed. Commonly used applications include detecting whether indoor carbon monoxide concentrations are higher than outdoor or detecting the source of carbon monoxide. It is very sensitive to the detection of carbon monoxide.
1. Turn the switch to the "AVG" or "NOR" setting to measure the concentration of carbon monoxide.
2. The stabilization time should be at least about 45 seconds.
3. Put the carbon monoxide meter outdoors and reset it to zero, then take it indoorsmeasurement.
4. Expose the sensor to a stable and continuous gas for sampling (see Precautions for details)
5. For the initial test, walk around the room with a carbon monoxide meter and observe that the carbon monoxide concentration in the room is the highest, please use a manual pump or stay away from the air conditioner. The hot airflow can affect the readings detected by the carbon monoxide meter. The temperature of the sample gas needs to be close to the ambient temperature.
6. Press "MAX" to read the maximum value.
Press "H" to lock the maximum value.
Press " " to turn on the backlight and press " " to turn off the backlight.
7. In the "AVG" file, you can read a more stable value.

Turn on the power and wait for about 30 seconds for the reading to be stable, place the carbon monoxide Detector in the air to allow it to react with the clean air that does not contain carbon monoxide, remove the lid of the "CAL", and adjust the potentiometer in the hole with the additional adjustment rod to within the range of 000±2ppm. If you are unsure about the quality of the surrounding air, you can apply oxygen or nitrogen and adjust it according to the above method. If there is a sudden change in the detected ambient temperature (e.g. taken out of the freezer into the air), it is necessary to wait at least 2 minutes before the measurement.
