In-Situ ColTechw2 Water Colour Sensor

In-Situ ColTechw2 Water Colour Sensor

The In-Situ ColTechw2 Water Colour Sensor monitors apparent colour in water, providing accurate, low-maintenance measurement for water treatment and process control.

The In-Situ ColTechw2 Water Colour Sensor is an advanced apparent colour measurement device for accurate, real-time monitoring in water treatment and process control. It quickly detects colour changes from dissolved organic matter, such as humic acids, or metals like iron and manganese, which cause an unwanted yellow tint. The built-in auto-clean system ensures consistent readings while keeping maintenance low.
Paired with the 7300w2 Monitor, this apparent colour measurement device provides repeatable results to optimise coagulation control, cut chemical usage, and keep potable water crystal clear. High colour readings immediately alert operators to treatment issues, allowing fast adjustments to prevent discoloured water entering the network.
Ideal for raw water, filtered water, clarifier supernatant, filter backwash control, and other process control applications, the ColTechw2 Water Colour Sensor offers a dependable way to maintain water quality and improve operational efficiency.
