Definition - What does Hygrothermograph mean?

A hygrothermograph is an instrument often used by meteorologists (weather experts) to measures humidity and temperature. A hygrothermograph is also useful for monitoring the surroundings in order to manage corrosion.

Corrosionpedia explains Hygrothermograph

A hygrothermograph is a device that combines a thermograph and a hygrograph for simultaneous and continuous recording of the temperature and humidity on the same chart.

Thermographs are devices used to detect infrared radiation and produce corresponding images (thermograms) of it. This is possible because infrared radiation is emitted by all objects with a temperature above absolute zero; this is often referred to as objects that give off a "heat signal". Thermography views temperature variations via a thermograph. The image is captured by a thermal imaging camera and has wide-spread use in military and security surveillance operations.

A hygrograph serves a similar purpose, except with moisture as its measured parameter instead of heat or radiation.
