Temperature/Humidity Sensor is
pre-installed inside Fan Aspirated Radiation Shield. Combines both active and
passive aspiration to minimize the effects of radiation. Motor-driven fan draws
air through the sensor chamber and exhausts it through the top of the shield.
For maximum natural cooling, triple-walled sensor chamber is shielded by
flow-through plates. Aspiration rate is 220 feet (67 m) per minute. At night,
when the fan is being run on battery power and the effects of radiation are
less, the aspiration rate is 120 feet (36 m) per minute.
Includes industrial Temperature/Humidity Sensor with 16' (5 m) shielded
cable, solar panel and battery.
