01 · Start with the actual sample
Evaluate color, turbidity and installation together
PCT-600 uses visible-light photometry based on the platinum-cobalt color scale. Turbidity, suspended solids, bubbles, fouling and installation location in the actual water can affect selection and maintenance planning.
Range and interference
Provide minimum, normal and maximum color plus turbidity, suspended solids, bubbles and fouling.
Mounting and cleaning
Confirm pressure, immersion position, mounting, automatic-cleaning need and maintenance access.
Interfaces and delivery
Confirm cable, 4–20 mA, relays, RS485, power, quantity and project destination.

03 · Operating applications
Typical color monitoring applications
For continuous Pt-Co color measurement in raw water, secondary supply, drinking water and surface water.
Source water
Continuously monitor color changes at source-water and plant-intake points.
Secondary water supply
Track color in managed secondary-supply systems.
Drinking water
Add continuous color monitoring to drinking-water quality control.
Surface water
Observe color trends in rivers, lakes and environmental monitoring projects.
04 · Common questions
Confirm this information before an inquiry
How does PCU relate to the documented degree value?+
PCU is used as the internationally recognizable color-navigation label. The PCT-600 source values remain stored as 0–100 degrees on the platinum-cobalt scale.
Why are two accuracy values stated?+
The source specifies ±10% or ±1 degree, whichever is greater.
Does the measurement require reagents?+
No. The supplied sheet states direct-immersion visible-light photometry without sampling or chemical reagents.
Can the website image replace a technical drawing?+
No. It provides consistent public presentation. The Ø34 × 244 mm sensor dimensions, transmitter dimensions and mounting remain controlled by the datasheet and order confirmation.
