HYGRASGARD
The calibratable humidity and temperature sensor HYGRASGARD
measurands humidity and temperature into standard signals of 0 - 10 V. The showcase sensor VFF / VFTF is especially designed for installation in
ceilings or walls, inside showcases or display cabinets, in museums, galleries, cinemas, in lecture halls or laboratories. The measuring element is
contained inside a stainless steel probe, the sensor is pluggable on one side or optional on two sides, at the probe and ⁄ or at the electronics enclo-
sure. Because of its very low height (approx. 5 mm), it barely protrudes and is virtually invisible.
