Do not put the sensor in red pH 4 buffer. Red pH 4 buffer can cause permanent damage to the sensor lenses. As
an alternative, use pH 4 buffer with no color.
The blue-green algae freshwater sensor is an optical fluorometer that determines the concentration
of blue-green algae in freshwater. Refer to Figure 3.
This sensor is sensitive to light. For the best results, point the end of the sensor away from light
sources.
