DEPLOYMENT AND INSTALLATION

Mount the sensor to a solid surface with the nylon mounting screw provided to prevent galvanic corrosion. 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.

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 blue cap should be removed from the sensor. The blue cap can be used as a protective covering for

the sensor when it is not in use.

Nylon Screw: 10-32x3/8

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.
