The measurement data monitoringsystem testo Saveris in museums

We measure it.

The Deutsches Museum is one of the most important muse-

ums of natural sciences and technology worldwide. Many of

the more than 100,000 objects at the three sites in Munich

are extremely sensitive to temperature and humidity: For

example, the wood in historical coaches must be protected

from cracking, the metal in vintage cars from corrosion, and

astronauts’ space suits from mould. Data loggers from Testo

AG clearly display the current ambient values and deviations

from the limit values. The values are saved and archived in

the form of reports or climatic diagrams. The reports allow

lenders to quickly assess whether contractually stipulated limit

values are being adhered to.

In the musical instrument collection, the museum staff have

gone a step further. Humidity damage such as shrinkage cracks

in the sounding boards are a significant danger for the sensi-

tive pianos, harpsichords, spinets and virginals. Probes from

the measurement data monitoring system testo Saveris today

monitor the indoor climate. Measurement, documentation and

alarms (when limit values are violated) are all carried out au-

tomatically.

The benefits at a glance:

•Uninterrrupted monitoring of temperature and humidity

values with the Testo data loggers

•Reliable, manipulation-proof recording of climate values

• Large, easily legible display; longlife batteries; storage

space for up to 1 million measurement values

•Automatic measurement, documentation and alarms

(audible, optical, by SMS or e-mail) with testo Saveris

•User-friendly, intuitively operable measuring instruments

with software solutions

The measurement data monitoring system testo Saveris with its components

Temperature and humidity measurements are required in theDeutsches Museum for various reasons:• Exhibits such as the keyboard instruments of the musical in-strument collection are particularly sensitive to temperature andhumidity. Climate values and limit value violations must be reli-ably monitored, stored and documented.

• Some exhibition rooms can develop into climatically critical areasdepending on the weather conditions. Against this background,

the measuring instruments must be flexibly applicable and easyto use.

• The adherence to agreed temperature and humidity values mustbe provable to lenders. For this reason, the climate data must beclearly, uninterruptedly and graphically documented in weekly ormonthly reports.

The Deutsches Museum, founded1903 in Munich, is today the mostheavily frequented museum in Germany, with 1.3 million visitorsannually. It displays objects from around 50 areas of the natural

sciences and technology over an area of73,000 m². The objective of the museum’smanagement is to bring scientific and tech-nical insights closer to the visitors in an un-derstandable way. In addition to the mainbuilding on Museum Island, further attrac-tions are the aviation museum FlugwerftSchleissheim and the traffic centre at There-sienhoehe, as well as the Deutsches Mu-seum Bonn.

The testo 175 H1 data loggers are characterized by awide measurement range, a high level of accuracy and byreliablility, flexibility and operational convenience. Longlifebatteries, a battery status display, a large storage ca-pacity, as well as a wall bracket included in delivery, arefurther benefits. Added to this are easy progamming by

USB cable, readout of data also by SD card, and report creationin the form of climatic graphs among other options.With the measurement data monitoring system testo Saveris, theDeutsches Museum has fully automated the monitoring of ambi-ent conditions, initially in an especially critical area, the musicalinstrument collection. If upper or lower limit values are exceeded,testo Saveris alarms the sanitation and heating technicians of themuseum by SMS or e-mail.

The solution

The Testo data loggers are used for stationary and single-pointmeasurements at the Deutsches Museum. They record theambient values in depositories, exhibitions, showcases and glassdisplays. With their help, it is possible at any time to determinewhether valuable exhibits are in danger dueto humidity, heat or cold, whether thehumidifying system in a room needs to beswitched on, or whether an exhibition mayeven need to be temporarily closed due tothe high summer temperatures. The au-tomation and alarm options of the measure-ment data monitoring system testo Saverisadditionally offer the highest level of produc-tivity and convenience.
