You can access all measuring values and analysis functions at any time and from anywhere with an internet-capable smartphone, tablet or PC.

    The WiFi data logger testo 160 THE – adaptable and discreet

    The small dimensions of the testo 160 THE (64 x 76 x 22 mm) and its simple design enable it to be positioned easily in an exhibition or display cabinet. In conjunction with the optionally available customisable deco-cover (see accessories), the data logger can be adapted to blend in with the surroundings and therefore remains inconspicuous. This means your exhibits will always be the focus.

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

    The Testo Cloud is the core operating element of the testo 160 data logger range. You can use the testo 160 THE to store your measurement data in the Testo Cloud via an available WLAN. Here you can configure your WiFi data loggers, set limit value alarms and analyze your measurement data.

    Installing the system is simple and can be carried out via a browser.

    Depending on the desired range of functions, you have a choice between the free Basic and more extensive Advanced functionality for use of 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.

    Areas of application for the WiFi data logger testo 160 THE: museums, archives and storage depots

    Use the integrated sensor to measure the temperature and humidity in the display cabinet, exhibition room or storage depot constantly and reliably. With separately available connectable probes, illuminance or illuminance and UV radiation or temperature and humidity can be measured. Connect, for example, the humidity/temperature probe for simultaneous measurement in both the exhibition room and the display cabinet. The professional WiFi data logger testo 160 THE is optimised for applications relating to the monitoring of ambient conditions in museums, galleries or other exhibition venues. It can be used to reliably protect your sensitive and valuable exhibits against damage.

    Further advantages and functions of WiFi data logger testo 160 THE

    The internal data store capacity of the WiFi data logger is 40,000 measuring values, and the housing is protected according to IP20. The standard batteries have a lifetime of 12 months and can be replaced at any time by users. Alternatively, the data logger can also be operated without batteries using a mains unit (please order separately) via the USB interface provided.

              Monitoring the micro-climate in a display cabinet 

              Reliable monitoring of ambient conditions in a display cabinet plays a decisive role in protecting valuable and sensitive exhibits. An unstable micro-climate in the display cabinet can result in damage to the objects. A WiFi data logger in the testo 160 range detects when limit values are critically exceeded and ensures the safety of your museum objects through its alarm function. This small WiFi data logger can also be placed discreetly in a display cabinet.

              Checking and documenting the ambient conditions in the exhibition room 

              Paintings, sculptures and other exhibits may be badly damaged by an unsuitable climate in the exhibition room. Micro-cracks and fissures, which gradually grow larger, are the consequence of an unsuitable or highly fluctuating ambient climate. With WiFi data loggers in the testo 160 series, you can monitor the key parameters of temperature and relative humidity at all times. In this way, the WiFi data logger helps you to avoid climate-related damage. As loan items are often exhibited, a museum's reputation relies on the careful handling of such items. Consistent documentation of climatic conditions is generally included in a loan agreement. By storing data in the Testo Cloud, the museum can not only provide lenders with this documentation but can also offer them access at all times to the current climate conditions at their object. Thanks to the simple design and small dimensions, your WiFi data logger can be integrated into the room – without drawing attention.

              Protecting museum objects through light and climate measurements 

              Unsuitable light conditions, as well as the wrong indoor climate, pose a huge risk to exhibition objects. They accelerate natural ageing processes and cause irreparable micro-cracks and discolouration. Prevent exhibits from losing their value and preserve cultural heritage with a WiFi data logger from the testo 160 series. Use the WiFi data logger to monitor humidity and temperature, and check lux and UV radiation. In this way, you can protect your museum objects against climate-related damage and discolouration.

              Good ambient conditions inside the storage depot 

              Museums generally only exhibit a small proportion of their objects. As the majority of a museum's inventory is stored at a depot, reliable monitoring of the ambient conditions is particularly important here. Constant and suitable ambient conditions are important for decelerating the natural ageing processes of museum objects. A WiFi data logger from the testo 160 range helps you properly monitor and document the storage of your collections.
