COLORPLUS EX BYPASS

Absorption measuring Instrument bypass for hazardous areas

The ColorPlus is built to accommodate up to three different light sources (UV and visible range) for the measurement of color, DOC and concentrations. By use of the dichromatic measurement at separate wavelengths the turbidity can be compensated. Measurements are performed inline or in bypass cells, the selection of materials for the cell and housing depends on the requirements. A version with flameproof encapsulation is offered for installations in areas requiring explosion protection.

• Color/absorption measurement in liquids
• Protection class Ex d IIC
• Concentration measurement of substances by absorption at characteristic wavelengths
