Detailed Description
The 107 consists of a thermistor encapsulated in an epoxy-filled aluminum housing. The housing protects the thermistor allowing the probe to be buried in soil or submerged in water.

Additional Compatibility Information
Data Logger Considerations
One single-ended channel per probe is required; an excitation channel can be shared by several probes.
Installation Considerations
Air Temperature
When exposed to sunlight, the 107 should be housed in a 41303-5A, 41303-5B, or RAD06 6-plate radiation shield. The louvered construction of these radiation shields allows air to pass freely through the shield, thereby keeping the sensor at or near ambient temperature. The shields’ white color reflects solar radiation.
The RAD06 uses a double-louvered design that offers improved sensor protection from driving rain, snow, insect intrusion and has lower self-heating in bright sunlight combined with higher temperatures (> 24°C [~75°F]) and low wind speeds (< 2 m/s [~4.5 mph]), giving a better measurement.
The 41303-5A and RAD06 attach to a crossarm, mast, or usersupplied pipe with a 2.5 to 5.3 cm (1.0 in to 2.1 in.) outer diameter. The 41303-5B attaches to a CM500-series pole or a user-supplied pole with a 5.1 cm (2.4 in.) outer diameter.
Soil Temperature
The 107 is suitable for shallow burial only. Placement of the sensor’s cable inside a rugged conduit may be advisable for long cable runs—especially in locations subject to digging, mowing, traffic, use of power tools, or lightning strikes.
Water Temperature
The sensor can be submerged to 15 m (50 ft) or 21 psi. Please note that the 107 is not weighted. Therefore, the installer should either add a weighting system or secure the sensor to a fixed, submerged object, such as a piling.
Multiplexers
To measure large numbers of probes, the AM16/32B multiplexer is recommended.
