| Definition | A precision instrument for the measurement of air temperature and humidity by the wet and dry bulb method. A pair of 100 Ohm 4-terminal platinum resistance elements were enclosed in a double-walled enclosure with an optional radiation shield to minimise thermal radiation errors. The wet bulb element was enclosed by a wick leading to a 500 ml water reservoir (sufficient for 7 days) in a fan-driven airflow. Accuracy was quoted by the manufacturer as 0.2C with a response time of 50 seconds. The instrument was discontinued in 2010. | |
