Description
Technical Description – ColorPlus Ex
In-line and Bypass UV and Colour Measurement in Hazardous Areas
The ColorPlus Ex, in both inline and bypass configurations, is designed to accommodate up to three different light sources (UV and visible range) for the measurement of color, DOC and concentrations. For example, one (or two), of the colours can be used to measure concentration, and the third light source can be used for turbidity compensation, if turbidity is a potential complicating factor in your process.
This ColorPlus Ex version features a flameproof encapsulation and is offered for installations in areas requiring explosion protection.
