Walchem 190785 WCU310 Series Flow Through Copper Sensor

The copper flow through sensor is designed for out-of-tank monitoring of electroless copper and microetch solutions. The sensor is compatible with WCU series controllers; it is NOT compatible with Walchem W-10 series controllers. The sensor is designed with a glass tube that contains the copper solution that forms a fixed path length between the lamp and receptor module. The solution absorbs light at specific wavelengths in proportion to the copper concentration.

Note: IN ORDER TO AVOID A SHIFT IN CALIBRATION CAUSED BY CONDENSATION, THE SENSOR COVER SHOULD NEVER BE REMOVED!
