190784 Walchem Flow Through Nickel Sensor

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