FEATURES & BENEFITS
Combines Temperature and Humidity onto one sensing unit
Rotronics HygroClip S3 has interchangeable sensing elements requiring no calibration
Stacked plate construction of shelter provides natural ventilation
Quick-Release mounting bracket allows for easy installation and maintenance
Aluminum radiation shield is lightweight and extremely durable
White baked-enamel finish reflects most radiant heat from sun and surrounding objects
INSTALLATION & MAINTENANCE
The radiation shield with sensing element can be pole or mast mounted. Whenever possible, sensors should be
installed at a height of 4 ft. (1.2 meters) or greater over earth or sod at least 100 ft. (30.48 meters) away from
any concrete or other hard-surfaced area and not closer to any other object than four times the height of the
object above the instrument shelter or remote sensors. Avoid roof installations if possible. If it is necessary to
roof-mount shelters and sensors, they should not be closer than 30 ft. (9.14 meters) to any large, vertical
reflecting surface (walls, etc.), exhaust fans, or cooling towers. Electronic remote sensors when roof-mounted
should be at least 9 ft. (2.74 meters) or greater above the roof surface. To minimize radiation effects from the
roof, they can also be mounted on a horizontal boom so that they will extend from the side of the building roof
or tower assembly.
