Product Description

The testo 160 THL is a part of the testo 160 data logger family developed specifically for the needs of museums.  This system allows for the configuration of internal sensors and external probes, to match any monitoring situation in a museum or archival setting.
The logger data is accessible at any time from any browser enabled device, such as a smart phone, tablet, or a PC or Mac.

Monitoring temperature, humidity, illuminance, and UV radiation with the testo 160 THL Wi-Fi data logger
The testo 160 THL Wi-Fi data logger provides a complete, single instrument solution for monitoring humidity, temperature, illuminance, and UV, from a single mounting point location.  One discretely mounted instrument will record four important environmental factors that affect the material integrity and color of displayed artwork or historical objects.
 
The testo 160 THL Wi-Fi data logger – unobtrusive and easy to hide
So as not to distract from your art exhibit, the testo 160 THL logger was made small, about 2.5x3.6x0.95 inches. To make it easy to conceal in an exhibit or a display case, an optional paintable deco cover is available to help the logger blend in with its surroundings.

A perfect network appliance – uses an existing Wi-Fi network to send data to the Testo Cloud
The Testo Cloud is a central data repository for all of your testo 160 THL data loggers.  On your Testo Cloud account, you can configure data loggers and set alarm points, designate authorized users, and set recipients for alarms and monitoring reports.
To start, register at www.museum.saveris.net to gain access to your account.  To register you can use a browser, or our Saveris 2 phone app for iOS or Android.
Depending on your needs, you can select between the free Basic or subscription based Advanced functionalities as needed, to create 10 user accounts, or add text messaging of alarms, for example.

Museum, archive, and storage applications for the testo 160 THL Wi-Fi data logger
Measure and collect temperature, humidity, lux, and UV exposure data on an exhibit room or storage area reliably and without interruption.  The professional testo 160 THL Wi-Fi data logger is optimized for monitoring applications of ambient conditions in museums, galleries, and archives.

Additional functionality of the testo 160 THL Wi-Fi data logger
The logger comes with a large internal memory for 40,000 measurement values to protect your data, in case of a blackout or Wi-Fi network issues.  The logger housing has IP20 moisture protection, and uses readily available, standard alkaline batteries.  The batteries are monitored, and should last for about 12 months.  The logger can also be powered by an external USB power supply, and in such a case, the batteries will be used only during a loss of power.

Monitoring the microclimate in a display cabinet

Reliable monitoring of ambient conditions in a display cabinet plays a decisive role in early warnings of potential problems.  An unstable microclimate in a display cabinet can result in artwork damage.  A Wi-Fi data logger from the testo 160 family will detect when preset alarm points are crossed, and it will send notifications.  This small Wi-Fi data logger can also be placed inside the base of a display cabinet, with a small external probe hidden in proximity to the displayed object.

Checking and documenting ambient conditions in an exhibit room

Paintings, sculptures, and other displayed items may be damaged by an unsuitable exhibit room climate.  Microcracks and fissures, which gradually grow larger, are the consequences of an unsuitable or highly fluctuating ambient climate.  With the testo 160 series Wi-Fi data loggers, you can always monitor the key parameters of temperature and relative humidity.  As loan items are often exhibited, loan agreements often require documentation of an exhibit’s ambient environment.  The testo Cloud data storage can allow lenders to view current climate conditions at any time.  Testo 160 loggers can be paired with optional paintable covers, to allow for concealment within an exhibit space.

Protecting museum objects using light and climate measurements

Unsuitable light conditions, in addition to improper indoor climate, pose a risk to exhibited objects.  They accelerate natural aging processes, and can cause irreparable microcracks and discoloration.  Monitoring with the testo 160 series for light, UV, temperature, and humidity levels exposure can help preserve cultural heritage.

Good ambient conditions inside a storage depot

Museums generally only exhibit a small portion of their objects.  As the majority of a museum's inventory is in storage, reliable monitoring of ambient storage conditions is important, as well.  Constant and suitable ambient conditions are important for slowing the natural aging processes of museum objects.  A Wi-Fi data logger from the testo 160 series helps you monitor and collect data, and document the storage conditions of your collections.
