Гигрометр-психрометр ВИТ-2 (+15…+40°С,)

Назначение прибора:

Измерение относительной влажности и температуры воздуха в помещении.

Принцип действия:

Основан на зависимости между влажностью воздуха и психометрической разностью – разностью показаний «сухого» и «увлажнённого» термометров, находящихся в термодинамическом равновесии с окружающей средой.

Конструкция:

Состоят из пластмассового основания, на котором закреплены температурная шкала с двумя капиллярами, резервуар одного из которых увлажняется фитилём из ткани, опущенным в питатель с водой, и таблица для определения относительной влажности воздуха по разнице показаний «сухого» и «увлажнённого». Питатель закреплён с внутренней стороны основания. Шкальная пластина и таблица – металлические.
