DEPLOYMENT AND INSTALLATION

Mount the sensor to a solid surface with the nylon mounting screw provided. To accurately measure PPFD incident

on a horizontal surface, the sensor must be level. An Apogee Instruments model AL-100 Leveling Plate is

recommended to level the sensor when used on a flat surface or being mounted to surfaces such as wood. To

facilitate mounting on a mast or pipe, the Apogee Instruments model AL-120 Solar Mounting Bracket with Leveling

Plate is recommended.

Nylon Screw: 10-32x3/8

To minimize azimuth error, the sensor should be mounted with the cable pointing toward true north in the

northern hemisphere or true south in the southern hemisphere. Azimuth error is typically less than 1 %, but it is

easy to minimize by proper cable orientation.

In addition to orienting the cable to point toward the nearest pole, the sensor should also be mounted such that

obstructions (e.g., weather station tripod/tower or other instrumentation) do not shade the sensor. Once

mounted, the green cap should be removed from the sensor. The green cap can be used as a protective covering

for the sensor when it is not in use.

Model AL-100

Important: Only use the nylon screw provided when

mounting to insulate the non-anodized threads of

the aluminum sensor head from the base to help

prevent galvanic corrosion. For extended

submersion applications, more insulation may be

necessary. Contact Apogee tech support for details.
