See how NGV protect their priceless artwork in Australia and around the world.

The National Gallery of Victoria (NGV) is Australia's oldest cultural institution. Established in 1861, the gallery now has a collection of over 70,000 items, displayed over two sites in Melbourne’s city centre. The Gallery boasts up to 45 exhibitions a year, displaying both Australian artwork and prestigious collections from around the globe, making NGV one of the most renowned art institutions worldwide.

A team of approximately 25 conservators and specialist technicians are charged with caring for and maintaining the Gallery’s collection. Two of the team are devoted solely to works on loan from external parties, including other state institutions and galleries worldwide. It's an important responsibility, but one Conservator for Exhibitions and Loans, Janelle Borig, takes it in her stride.

''There is definitely added pressure when you're looking after another institute's priceless works,'' says Janelle.

''I've been with the National Gallery for nearly 15 years now - and I've loved every experience. I graduated from a Conservation of Cultural Material degree through the University of Canberra, then had a nine year stint at the Bavarian National Museum in Munich, Germany. There, I was exposed to the processes that go into museum exhibition loans, which has given me a solid footing with my current responsibilities.''

Humidity, temperature and light exposure are all important factors when monitoring museum collections. Each element can cause material deterioration in different ways, while certain items may be more sensitive to a change in conditions than others. This makes recording environmental data vital.

''One of the main parts of my role is compliance monitoring for our cultural partners. When another institution loans us an artwork, they will provide specific climatic conditions the item has to be displayed at as part of the loan terms,'' Janelle says.

''We use climate dataloggers to monitor and prove we can maintain these conditions and fit global best practice standards, with relative humidity levels of between 45-60 per cent and temperature between 20-24 degrees Celsius.''

To meet these external requirements, the National Gallery of Victoria uses Testo's climate monitoring tools, the testo 160 TH and the testo 160 THL. Aligned with the National Gallery's building management system, the testo 160 TH and testo 160 THL records environmental data every 15 minutes, providing Janelle and other conservators with the data needed to ensure the safe-keeping of the artworks in their care.

Set up to notify the conservation team with alarms if environmental conditions fall outside of set parameters, Testo's system also collates data in daily reports that can be easily accessed and shared by staff whenever needed.
