Temperature and humidity measurements

Underpinning accurate measurements to support industry

Accurate and reliable temperature and humidity measurements are critical to healthcare, industry, meteorology and research. Businesses and organisations need to have complete confidence in the performance of their measurements, over a wide range of temperatures and even in the harshest conditions.

We can help you to increase understanding and confidence in the performance of your measurement instruments over relevant ranges and for different scenarios. With high-accuracy and optimised measurements, we can also enable improved yield, reduced cost and greater production process control. Our bespoke testing, characterisation and consultancy services can facilitate improved product quality via greater insight into the behaviour and performance of materials and components. As the UK's National Metrology Institute, you can trust the independence and impartiality of our findings.
