Belfort Hygrothermograph


An instrument that records temperature and relative humidity as a function of time. Analog hygrothermographs record continuous measurement on a chart wrapped around a rotating drum. The most common hygrothermograph is a hair hygrometer combined with a thermograph. It should be calibrated every two to three months with a psychrometer. Most hygrothermographs have been replaced by dataloggers.
