HYGRASGARD
The calibrateable humidity and temperature sensor HYGRASGARD
the measurands humidity and tempe rature into standard signals of 0 - 10 V. The showcase sensor HYGRASGARD
for installation in ceilings or walls, inside showcases or display cabinets, in museums, galleries, movie theatres, 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 enclosure. Because of its very little height (ca. 5 mm) it hardly builds up and is almost unconsiderable.
