The following values can be read off the logger display:
With mains operation: CO₂ concentration and alternately temperature and humidity. The atmospheric pressure values are not shown on the logger display, however they are available in the Cloud.
In battery mode: CO₂ concentration and temperature. The data for humidity are not displayed – because that ensures longer battery lives.
All measurement data are stored by the data logger directly in the Testo Cloud via your WLAN. This means you can also document and analyze your measurement data over a longer period of time.
If limit values are exceeded, you will be notified immediately by e-mail or (optionally) SMS thanks to the alarm function. You can access all measuring values and analysis functions anytime and anywhere with your internet-capable smartphone, tablet or PC.

The WiFi data logger testo 160 IAQ – adaptable and inconspicuous
The small dimensions of the data logger testo 160 IAQ (82 x 117 x 32 mm) and its simple design enable it to be easily positioned in any room. Especially for museums and archives, it is particularly important that the focus is always on your exhibits. In conjunction with the optionally available customizable deco-cover (see accessories), the WiFi data logger can be perfectly adapted to blend in with its surroundings and therefore remains particularly inconspicuous.
