Below is some more information on what we will have on stand and how testo equipment is useful to the museums and heritage sector.


Environmental monitoring in museums


Why is creating the right indoor climate in a museum a challenge?

Suitable room temperature – a challenge for museums

Preserving the exhibits from damage is of course a top priority for museums. This becomes particularly important with the liability obligation towards the owners of loaned objects and priceless artifacts. Since many exhibits are extremely climate-sensitive, suitable air temperature and humidity conditions are essential. This is not an easy job because of seasonal climate fluctuations caused by high numbers of visitors. You cannot rely on just the correct adjustment of the air conditioning systems. For this reason, comprehensive and continuous humidity and temperature monitoring is a necessity.


How does humidity and temperature monitoring with Wi-Fi data loggers work?

With testo Saveris 2, indoor climate monitoring is easy. Just place a Wi-Fi data logger in each location you wish to monitor. The Wi-Fi data loggers continuously measure temperature and humidity and wirelessly transmit the measurement data to the cloud (online storage). The data is automatically saved there (no additional storing on hard drives/servers is necessary). You can access these readings at any time, using your smartphone, tablet or PC. You are immediately provided with an alarm (by text or e-mail) in cases of critical temperature or humidity values and can react quickly to threats of damage.


How can a Saveris 2 system help me to preserve precious artifacts in the museum?

Once the Wi-Fi data loggers are connected to your wireless network (this is very simple), they are very reliable. Temperature monitoring is automated so you do not need to write down any min./max. values, read out data loggers, or sort the measurement data before saving. You can then access all your data via PC, smartphone or tablet, in order to check the values or to provide proof to auditors. Problems with updates or hard drive back-ups are a thing of the past.


What advantages does a Wi-Fi data logger system have over traditional data loggers?

WiFi data logger system for temperature monitoring

No more recording data by hand! The data from all your measurement locations is collected in the testo Cloud (even if you are measuring in several rooms or different floors of the museum). Also if you are planning on expanding, it couldn’t be easier to add additional loggers. You will receive a warning text or e-mail if temperature and humidity values are critical and can quickly take action to prevent threats of damage. The Wi-Fi data logger system simply offers you more security for the preservation of the exhibits.


With a Saveris 2 system museum climate can be continuously monitored without you having to lift a finger. The data will then be automatically collated, and sent to you as a report via email. For more information on Saveris 2 watch the video below:

The above video explains how Saveris 2 works


Transportation and shock

Whilst temperature and humidity monitoring is well established in the heritage sector, there is a growing demand to monitor artifacts in transit. During transportation an artifact may endure shocks to it from handling and vehicle movement, which could cause unseen damage to the artifact, which would be hard to rectify.

The Testo 184 series can offer data loggers that will not only monitor and record the temperature and humidity, but can also monitor any shocks to the artifact during transit. Giving you a comprehensive data for the artifact during its transportation duration, which would allow for any action if necessary.


LUX testing

For museums in particular, light can be an important factor in the preservence of precious artifacts and paintings. Therefore it is crucial to make sure you have the right measures in place to monitor this. The sensor of the testo 540 LUX meter is adapted to the spectral sensitivity of the eye. This makes it ideal for the measurement of light intensity.

Restorers guide to Environmental Monitoring (Free whitepaper download)

Testo have recently launched a free guide to Environmental Monitoring for Restorers and those working with climate sensitive items. Protecting exhibits from damage is of course the number one priority for restorers. Since many artifacts are climate-sensitive, it is important to monitor air temperature and humidity.

The importance of this is further increased because of the liability obligation towards owners of priceless artefacts and loaned exhibits. For this reason continuous indoor climate monitoring becomes a necessity.

Climate monitoring in measurement rooms

Highly modern measurement rooms are used in many industrial companies for quality assurance purposes. However, since the materials change depending on the ambient climate, parameters including temperature and humidity must remain constant in order to obtain precise measurement values. This is defined in detail in the guideline VDI/VDE 2627. It also states that the monitoring of ambient conditions in a measurement room has to take place with suitable measurement technology.


Climate monitoring is of the utmost importance in measurement rooms


Temperature and air humidity can be continuously measured and documented using the measurement data monitoring system testo Saveris. In addition to this, the monitoring system has an innovative function which informs you by alarm even before a limit value violation occurs. Apart from this, it offers interfaces for integrating further measuring instruments for the monitoring of the other parameters defined by VDI/VDE 2627.


The challenge

The demands placed on measurement rooms are high – after all, they represent a fundamental basis for product quality. Above all, stable ambient values are of crucial significance, since temperature and humidity fluctuations have a direct influence on the properties of materials. Shrinkage or expansion of only 1 μm can already have drastic consequences for later serial production.


Precision measurement of a component in a measurement room


As well as the quality class of the measurement room, the basis temperature defined for the respective measurement room and a relative humidity of between 30 % and 60 % are additionally relevant. Only this way can results be obtained which are always comparable and reliable. But how can you ensure that these parameters remain within the defined limit values, and that an unnoticed deviation does not endanger quality and cause unnecessary costs?


The solution

The measurement data monitoring system testo Saveris can reliably and automatically fulfil the continuous measurement of temperature and air humidity required by the guideline VDI/VDE 2627 for measurement rooms. Added to this is the innovative function “trend alarm” which makes monitoring climate even easier for you: It calculates the projected temperature development by linear regression over the last four measurement cycles, and provides you with an alarm even before a limit value violation occurs.


Monitoring ambient conditions in a measurement room with testo Saveris data loggers


Here’s an example of this: You want to receive an alarm as soon as the temperature of your measurement room increases by 5 Kelvin within one hour. You have set the measurement cycle so that the temperature is measured every ten minutes. In the forty minutes between 17:01 and 17:40, testo Saveris measures a temperature increase of 4 Kelvin.

It calculates from this that in 60 minutes, a temperature increase of 6 Kelvin would have occurred – and therefore already issues you with an alarm by e-mail, SMS, alarm relay, audible signal or LED display after 40 minutes. This allows you to intervene before it is too late.testo-saveris-systemWant to find out more about testo’s Saveris?
