Air Quality Carbon Dioxide Datalogger
The Extech CO210 measures and datalogs CO2 level, air temperature, humidity, date and time. With visible and audible alarms, this is an ideal instrument for indoor air quality (IAQ) diagnosis. This meter is shipped fully tested and calibrated and, with proper use, will provide years of reliable service.
The meter starts measurements when powered on and updates readings every second. If the operating environment changes (ex. from high to low temp.), it takes 2 minutes for the CO2 sensor to respond and 10 minutes for RH change.
NOTE: Do not hold the meter close to your mouth or any other source of CO2.
| Function | Range | Resolution | Accuracy |
| CO2 | 0 to 9999ppm | 1ppm | ±(5%rdg +50ppm) |
| Temperature | -10 to 60°C 14 to 140°F |
0.1° | ±0.6°C/0.9°F |
| Humidity | 0.1 to 99.9% | 0.1% | ±3%(10 to 90%) ±5%(< 10% or > 90%) |
The meter can record readings of CO2, temperature and humidity for long time environment monitoring. The memory capacity is 15999 points (5,333 RH, Temperature and CO2 records). The sample rate is adjustable from 1 second to 4 hours 59 minutes and 59 seconds.
The meter features an audible alarm which will give warnings when the CO2 concentration exceeds the set limit. There are two settable limits, an upper limit that initiates the alarm and a lower limit to stop the alarm.
The meter emits beeps and displays the fan icon on the display when the CO2 level goes over the upper limit. The audible alarm can be stopped by pressing any key or it automatically stops when CO2 reading falls below the lower limit.
If the beeper is temporarily shut down, it will sound again when readings fall below lower limit and then go over the upper limit again or it the user presses the RESET button for more than 1 second to activate it.
The fan icon keeps flashing when beeps are manually shut down. It stops only when readings fall under the lower limit.
ABC (Automatic Baseline Calibration) establishes a baseline calibration to eliminate the zero drift of the infrared sensor. The ABC function is always "ON" when the meter is turned on. ABC is designed to calibrate the meter at the minimum CO2 reading detected during 7.5 days continuous monitoring (power on). It assumes that the area being tested receives fresh air with a CO2 level of approximately 400ppm at some period of time during the seven days. It is not suitable to use desktop CO2 in closed areas with consistently high CO2 levels 24 hours a day.
