R220 Temperature/Humidity Transducers

These compact and lightweight transducers are dry and wet bulbs type temperature/humidity sensors with ventilating function.
The units employ two platinum resistance thermometers as temperature detecting elements for dry and wet bulbs, and consist of a ventilating unit, detecting elements, and a water tank for wet bulb, and others. Since the water tank is detachable and a terminal board is exposed when tilting the units forward under the wallmount condition, the wiring, check and maintenance are very easy.
