Testo 160 IAQ - WLAN logger with display and integrated sensors for temperature, humidity, CO2 and absolute pressure

The testo 160 IAQ logger is used for monitoring indoor air quality.
With the help of an integrated sensor for temperature, humidity, CO2 and atmospheric pressure, it precisely determines the climatic conditions in each room - also a long-term measurement.

The recorded measurement data is transmitted via WLAN directly to the Testo Cloud. If limit values are exceeded, the user is notified via email or SMS (optional).
The measurement data readout is available for live viewing and analysis at any time and place using a smartphone, tablet or computer.

Thanks to the small size of the testo 160 IAQ logger (82 x 117 x 32 mm) and its simple design, it can be installed in any room. In cooperation with deco-covers (optional), the logger can blend in with its surroundings and remain invisible.

The Testo Cloud is an essential component for using the Testo 160 IAQ logger. It allows stored data to be stored in the Testo Cloud via WLAN. The user can configure the WLAN logger, set alarm limits and analyze stored measurement readings.

Depending on the required functions, you can choose between a free license (Basic) and an extended license (Advanced) to use the Testo Cloud. In the case of the Advanced license, there is an option to create an account for 10 users, who will receive notification of exceeded limits via SMS.

Current measurement values, alarm value settings and the current battery status can be checked in real time on the recorder's display. LEDs provide information on air quality through a traffic light system. The display settings can be individually configured. The internal memory in the testo 160 E WLAN logger can store 40,000 measurement values, and the housing has an IP20 protection class.
