Product Description

Indoor air quality has a huge influence on people's health and well-being. Stale indoor air can lead to tiredness, loss of concentration and discomfort. Reliably monitor the indoor air quality in interiors with the WiFi data logger testo 160 IAQ. The data logger can for example be used in schools, nursery schools, conference rooms, open-plan offices, auditoriums or museums – in short:  in rooms where a lot of people gather.

Monitoring temperature, humidity, CO2 and atmospheric pressure with the WiFi data logger testo 160 IAQ

The easy-to-use WiFi data logger testo 160 IAQ is ideal for monitoring indoor air quality. Thanks to its probes for temperature, humidity, CO2 and atmospheric pressure, it accurately determines the ambient conditions in each room.

Particularly user friendly: in addition to the current reading, the indoor air quality is displayed using coloured LEDs according to the traffic light principle.

Measurement data are stored by the data logger via your WLAN directly in the Testo Cloud. This means you can also document and analyze your measurement data over a long 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 at any time 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. It is particularly important for museums and archives to ensure the focus is always on their 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.

Perfectly networked: with the WiFi data logger testo 160 IAQ and the Testo Cloud

You must first register at www.saveris.net to have access to the Testo Cloud. Installing the system is simple and can be carried out either via a browser or with the testo Saveris 2 App for IOS and Android.

Depending on the desired range of functions, you have a choice between the free Basic and more extensive Advanced functionality when using the Testo Cloud. You can use the Advanced functionality, for example to create up to 10 users per account or set an SMS alarm if limit values are exceeded.
