A thermometer is an instrument used to measure temperature and can be applied to calculate humidity. Electrical Resistance Thermometers (ERT or PRT), liquid-in-glass thermometers, wet bulb thermometers and Climate Data Loggers (CDL) are used by observation stations worldwide before data is used by the Met Office and later accumulated in the MIDAS dataset.

The Met Office Fact-sheet #17 – Weather Observations on Land describes the instrumentation further and includes diagrams of the apparatus set-up.
For more information on which instruments are used to collect measurements within specific station networks, the Met Office Surface Data Users Guide, describes the meteorological surface data and how it is obtained in the Met Office Database - MIDAS.
