  • A one day practical course on Coordinate Measurement Machine (CMM) Verification covering the twelve parts of ISO 10360 Geometrical Product Specifications (GPS) and the acceptance and reverification tests for CMMs.
  • A two day training course on understanding and evaluating measurement uncertainty, directed at practitioners concerned with more difficult measurement problems than those covered in courses on the uncertainty of measurement such as those provided by UKAS and NMO.
  • This workshop will instruct in safe working practices for users of lasers and is aimed at scientists and engineers using lasers in the laboratory and in industry. It will also be of use to safety advisers, managers of laser users, and product designers.

  • 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.
  • 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.
  • 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.
  • 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.
