  • Join leading mathematicians, statisticians and applications experts from Europe's National Measurement Institutes in Berlin, Germany, for three days of training courses, workshops, lectures and laboratory visits.
  • This year, for the first time, the Centre for Carbon Measurement at NPL will be co-exhibiting the EU's Environmental Technology Verification (ETV) scheme at Sustainability Live, a large UK exhibition for energy recovery technologies, innovative energy and resource management solutions, including lots of exciting features, networking events and conferences.
  • Meet NPL's Environmental Measurements Group at Stand 42 - we will be exhibiting and presenting at this event, which will include industrial emissions and stack monitoring, ambient air quality monitoring, and MCERTS standards.

  • 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.
