Applications
In the electroplating industry, nickel sulfate solution is the main raw material for nickel electroplating and chemical nickel plating. The solution is a dark green color. The absorption of the solution depends of on the concentration. The P5128 Electroless Nickel Controller is designed for monitoring the nickel-plating bath at all times, available to ensure that when the nickel concentration and/or pH fall below their pre-set values, Equipped with an automatic pump which accurately supplements the amount of dosing whenever might be required and maintains the optimal pH value of concentration in anytime.
Operational Principle
P5128 Electroless Nickel Controller has an on-line photometer, pH meter and an external temperature sensor in the plating bath. The Nickel ion (Ni-) electrolyte solution can absorb the light from a specific wavelength of LED lamp. Following Beer-Lambert Law, it can determine Nickel’s concentration. Accessing with pH electrode in the measuring loop can give the accurate date and provide controller to execute the auto dosing process. When the nickel ion (Ni-) electrolyte solution passes through the measurement cell, to identify the amount of nickel consist in the concentration, absorption of the light variation could be measured by the LED light wavelength. The result of the amount of nickel ion in concentration can be measured by the absorption of light at high and low points.
