Visible-light photometry follows the platinum-cobalt color scale for continuous online measurement
Pt-Co online color analyzer · PCT-600
Online Color Analyzer
A reagent-free visible-light photometric sensor for continuous color measurement. It can be immersed directly in the sample for source water, secondary supply, drinking water and surface-water monitoring.

Items to confirm
Online color selection requires more than the 0–100 degree range: actual water, turbidity, suspended solids, bubbles, fouling and installation conditions must also be confirmed.
- 01Water-matrix type, monitoring objective and color-control requirement
- 02Minimum, normal and maximum color
- 03Turbidity, suspended solids, bubbles and sensor fouling
- 04Pressure, mounting, automatic cleaning and maintenance access
- 05Cable, power, 4–20 mA, relays and Modbus RS485

Selection questions
What measurement method does PCT-600 use?+
It uses visible-light photometry based on the platinum-cobalt color scale and supports direct-immersion continuous measurement.
How is accuracy determined?+
The source specifies ±10% or ±1 degree, whichever is greater.
Are reagents required?+
No. The supplied sheet explicitly states that sampling and reagents are not required.
Can the website image replace a technical drawing?+
No. The clean image is for public presentation. The Ø34 × 244 mm sensor dimensions, transmitter dimensions and mounting remain controlled by the datasheet and order confirmation.
