DEPLOYMENT AND INSTALLATION
Apogee MQ series quantum meters are designed for spot-check measurements, and calculation of daily light integral (DLI;
total number of photons incident on a planar surface over the course of a day) through the built-in logging feature. To
accurately measure PFFD incident on a horizontal surface, the sensor must be level. For this purpose, each MQ model comes
with a different option for mounting the sensor to a horizontal plane.
MQ-300 series line quantum sensors are leveled using the built-in bubble level located in the handle of the sensor. In
addition to leveling, all sensors should also be mounted such that obstructions (e.g., weather station tripod/tower or other
instrumentation) do not shade the sensor.
The AL-210 leveling plate is recommended for
use with the MQ-100.
The AL-100 leveling plate is recommended for
use with the MQ-200. To facilitate mounting to a
cross arm, the AM-110 mounting bracket is
recommended for use with the AL-100.
