In recent years, with the rapid progress of agricultural science and technology, a variety of advanced instruments have emerged on the market. Among them, carbon dioxide detectors are mainly used in animal husbandry, industry, public places, agriculture and other fields. The absorption principle of infrared light source is used to detect carbon dioxide gas in the field environment. So what is the correct use of the carbon dioxide detector? The following is a small part of the cloud to explain the relevant content.

& nbsp;

carbon dioxide detector the correct use method is as follows:

& nbsp;

power on start: turn on the adapter, the carbon dioxide detector will automatically start, starting a short beep. If the voltage is too high or too low, bAt will be displayed on the LCD and the indicator will flash. The LCD display will display the current carbon dioxide concentration, temperature, humidity, date and time, as well as the air quality level.

& nbsp;

Measurement: After power on, the meter will start measuring and update the reading every second. If the working environment changes (for example, from high temperature to low temperature), the carbon dioxide sensor takes 30 seconds to respond, and the relative humidity takes 30 minutes to respond.

& nbsp;

Alarm and output: The instrument has an audible alarm device, which will sound an alarm when the carbon dioxide concentration exceeds the set value. Two limits can be set-an upper value to start the alarm and a lower value to stop the alarm. When the CO2 concentration exceeds the upper limit, the meter beeps and displays the fan icon.Press any button can stop the sound alarm, nitrogen dioxide concentration reading dropped below the lower limit will automatically stop. If the alarm is temporarily turned off, the alarm will sound again after the reading drops below the lower limit and then exceeds the upper limit again. The user can also press the reset button for more than one second to activate the alarm. The fan icon flashes when the beep is canceled manually. Stop blinking only when the reading is below the lower limit.

& nbsp;

content range: when the bubble diameter exceeds the spherical ruler scale, rotate the tester 90 degrees to make the bubble rise to the top of the absorption ball a thin tube, and read the scale indicated by the liquid level of the absorption ball a thin tube as the content of carbon dioxide. this method is applicable to the content range of 99% ~ 99.75.

& nbsp;

the above is a small compilation to share the use of carbon dioxide detector. readers can be more handy in using the instrument and improve the utilization rate of the instrument.
