Description

Extech CO250 Portable Indoor Air Quality CO2 Meter Details

This all-encompassing indoor air quality tool is used to measure carbon dioxide, temperature, humidity, dew point and wet bulb.

The CO250 can measure CO2 from 0 to 5000ppm, temperature from 14 to 140°F (-10 to 60°C) and humidity from 0.0 to 99.0%. Measurements are calculated via the tester's maintenance-free NDIR (non-dispersive infrared) CO2 sensor that is equipped to the top of the unit and all measurements are shown on the tester's triple LCD screen at the same time.

In addition to these standard measurements the CO25 can also be used to calculate statistical weighted averages of TWA (8 hour time weighted average) and STEL (15 minute short term exposure limit).  This indoor air quality meter can also be used to send information about testing results directly to PC via the use of the included cable and software (no internal memory is available on the device).

Additional functions of this tester include a user programmable audible alarm, a data hold function and the ability to be calibrated via the use of Extech's RH300-CAL calibration bottles (sold separately).

Good product, no external power source, cheap plastic looking

I have tried using it as a logger but it turns off after 15 minutes even the battery is good enough. There is no external power adapter and the user manual nowhere mentions the reason for auto swtich Off. You will need to spend more money purchasing a 9V DC adapter.
The quality of the plastic feels very cheap so nowhere the price I paid for it.
Measurements seem to be accurate and the device nicely calibrated.
