Campbell Scientific 107-L Temperature Probe - Manual (Page 14)

Model 107 Temperature Probe
Standard air temperature measurement heights:
• 1.25 to 2.0 m (WMO)
• 2.0 m (EPA)
• 2.0 m and 10.0 m temperature difference (EPA)
When exposed to sunlight, the 107 should be housed in a 41303-5A or 41303-
5B six-plate solar radiation shield. The louvered construction of the shields
allows air to pass freely through, thereby keeping the probe at or near ambient
temperature. The white shields reflect solar radiation. The 41303-5A attaches
to a crossarm, mast, or user-supplied pipe with a 2.5 to 5.3 cm (1.0 to 2.1 inch)
outer diameter. The 41303-5B attaches to a CM500-series pole or a user-
supplied pole with a 5.1 cm (2.4 inch) outer diameter.
Tools required for installing a radiation shield to a tripod or tower include:
• 1/2 inch open end wrench
• small screw driver provided with datalogger
• small Phillips screwdriver
• UV resistant cable ties
• small pair of diagonal-cutting pliers
