  • Educate + Explore

    Educate + Explore

    We strive to actively promote public awareness and appreciation of science and technology, particularly the importance of measurement and the role of NPL. Here you can find out more about the interesting things we do, science outreach activities you can get involved in or take a look at some of our educational resources.

    Outreach Activites

  • NMS Learning Zone
  • Measurement Network

    Measurement Network

    For anyone with an interest in measurement. It aims to facilitate the sharing of measurement knowledge and information between NPL scientists and members of the network, as well as providing a forum for the sharing and exchange of information and advice between members and other measurement experts.

  • Differential Scanning Calorimetry (DSC) measures the temperatures and heat flow in materials as a function of time and temperature, providing information about physical and chemical changes that involve a change in heat capacity or external temperature.
     
  • The electromagnetic anechoic chamber is used to calibrate antennas at frequencies up to 18GHz. The room is specially designed to absorb any and all electromagnetic waves, allowing precise measurements to be made without interference.
     
  • The NPL apparatus for single molecule imaging. By using three lasers (red, green and blue) we can use three different colours of fluorescence, enabling us to monitor up to three different types of molecule in the same experiment.
     
  • A polyurethane tile developed as an acoustic absorber for sonar frequency water tanks. The tile, developed through proof-of-concept funding, has properties which make it very absorbing and minimally reflective to water-borne sound above a frequency of 20 kHz.
     
  • This strontium end cap ion trap could redefine the way that the world measures the second. Current time measurements are made using caesium fountain clocks, but the team working on the ion trap clocks estimate that they could measure time up to 1000 times more accurately.
     
  • The UV Dosimeter, created by scientists at NPL, helps to minimise the risk of ultraviolet treatment by measuring the dose given as accurately as possible. UV treatment is used for skin conditions such as psoriasis and eczema.
