1. Introduction
The CS310 accurately measures photosynthetic photon flux density (PPFD) in both natural and
artificial light. PPFD is the number of photons in the 400 to 700 nm waveband incident per unit
time on a unit surface. Typical applications include PPFD measurement over plant canopies in
outdoor environments, greenhouses, and growth chambers, as well as reflected or under-canopy
(transmitted) PPFD measurement in the same environments.

2. Precautions
l
section at the back of this manual.
l
Care should be taken when opening the shipping package to not damage or cut the cable
jacket. If damage to the cable is suspected, contact Campbell Scientific.
l
Although the CS310 is rugged, it should be handled as a precision scientific instrument.
l
Keep the sensor clean. The vertical edge of the diffuser must be kept clean to maintain
appropriate cosine correction.
l
Clean the sensor only with water, mild detergent, or vinegar. Alcohol, organic solvents,
abrasives, or strong detergents harm the acrylic materials, which will adversely affect the
cosine response of the sensor.
l
The black outer jacket of the cable is Santoprene® rubber. This compound was chosen for
its resistance to temperature extremes, moisture, and UV degradation. However, this jacket
will support combustion in air. It is rated as slow burning when tested according to U.L. 94
H.B. and will pass FMVSS302. Local fire codes may preclude its use inside buildings.
