Chl-aChlorophyll-a measurement
01
Evaluate chlorophyll distribution and turbidity together
The supplied PCH-800A sheet notes that chlorophyll may be non-uniformly distributed and recommends multipoint monitoring. It also documents a turbidity condition below 50 NTU, so selection must include the actual water matrix and point layout.
02
Confirm these conditions before selection
Range and turbidity
Provide minimum, normal and peak chlorophyll plus normal and upset turbidity.
Point layout
Confirm stratification, representativeness, monitoring-point count and immersion position.
Materials and interfaces
Confirm standard or seawater material, cable, power, 4–20 mA, relays and RS485.

Chlorophyll-a selection questions
Why is multipoint monitoring recommended?+
Chlorophyll can be non-uniformly distributed in a water body, so one point may not represent the full site.
Can the standard condition be used above 50 NTU?+
The supplied sheet documents turbidity below 50 NTU. Higher-turbidity duty requires review of the actual sample and process.
