FEATURES & BENEFITS
• Combines temperature and humidity in one sensing unit
• Vaisala HMP60 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 powder-coat 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 re-
mote sensors, when roof-mounted, should be installed 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
they extend from the side of the building roof or tower assembly.
