摘要： An automatic titration system that periodically and automatically determines the pH level and acid number of a flux solution in a flux reservoir associated with an automatic flux application apparatus. The automatic titration system pulls the flux solution from the flux reservoir of the fluxing machine on a continuous basis to be filtered. Flux to be sampled by the automatic titration system is deposited in a titration chamber where a titration analysis is performed. A known reagent solution is mixed with the flux solution in the titration chamber to determine the pH level and acid number of the sampled flux during the titration operation. Containers of flux solution and thinner solution located in the automatic titration system allow flux and thinner to be dispensed into the flux reservoir depending on the outcome of the titration analysis, so as to maintain the flux in the flux reservoir at the desirable pH level and acid number.
