Inline Process Colorimeter

在线过程色度计

Process engineers who want colour or concentration data without pulling samples can plumb this colorimeter straight into a 6–12 mm line. It measures transmission over 400–700 nm and sends 4–20 mA and RS-485/Modbus signals to the control system. The IP65 housing suits chemical, water, food and pulp plants. Specify line size and process fluid.

Measurement principle: Transmission photometry
Wavelength range: 400–700 nm
Measurement range: 0–100% transmission, concentration scaled
