Non-contact air temperature and humidity sensor to be demonstrated at CIM 2017

NCTAH - Non-contact thermometer and hygrometer

Non-contact thermometer and hygrometer developed in EMRP project will be shown at the EURAMET stand at International Metrology Congress

Long-term observations of essential climate variables are vital as society becomes increasingly affected by climate change. Air temperature and humidity are key parameters in climate processes and a big challenge for conventional contact sensors is the limited speed of response in the atmosphere. EMRP project Metrology for essential climate variables (ENV58 MeteoMet2) developed sensitive and fast responding sensors to quantify dynamic changes. Project partner NPL developed a non-contact thermometer and hygrometer which extends the principles of acoustic thermometry to cope with the difficulties of measuring in air. The instrument reports the spatially-averaged temperature, humidity and air density along a laser path, 30 times a second. It will be demonstrated on the EURAMET stand at CIM 2017.

This instrument and other innovative devices will be demonstrated on the EURAMET stand at the 18th International Metrology Congress (CIM 2017) on the 19-21 September 2017.
The full congress programme and registration details can be found on the congress website.
