Thermohygrograph (THG)A piece of equipment that records temperature
(thermo) and relative humidity (hygro). Sometimes called a hygrothermograph.
Usually the results are plotted instantaneously on a chart recorder.
To be effective thermohygrographs need to be well maintained and frequently
calibrated against a standard measuring instrument such as a sling
psychrometer.
Automatic computer-based dataloggers are preferable, being cheaper and
more versatile than thermohygrographs.
Tipping inThe attachment of one leaf or sheet of paper to another by
means of a narrow strip of adhesive along one edge of the leaf.
