Monitoring temperature, relative humidity, light and colour


Sensors such as these are used to measure temperature, relative humidity and light levels on our galleries

There are radio telemetric sensors throughout National Museums Liverpool's galleries and stores to measure the temperature, relative humidity and light levels. The sensors transmit this information by radio signal to a central controller. We collect and store the data to check that the environment is appropriate for the collections. We use low energy systems as far as possible to provide a stable environment for the collections.

Colour measurement


Measuring the colour of an object at Museum of Liverpool using a spectrophotometer

We measure and record the colour of an object using a spectrophotometer. We use this technique to record the colour of light-sensitive objects before, during and after they are displayed, to find out how quickly they fade.
