What is titration?
Titration is a bench test that measures how much active cleaner remains in a bath by neutralising a measured sample with a standard acid. It is the accurate way to control concentration — far more reliable than topping up by eye, refractometer, or by how the parts look.
A known volume of bath is dosed with an indicator and titrated with standard acid until the colour turns. The volume of acid used converts directly to a concentration figure using a factor supplied with the product.
It matters because both directions of error are expensive. Under-dosed baths leave residue that fails at inspection, and the usual reaction — extend cycle time — burns energy without fixing the cause. Over-dosed baths waste concentrate, increase drag-out, and on non-ferrous work can start etching.
A simple weekly log of concentration, pH and temperature turns bath management from guesswork into a controlled process, and it is the single most common thing missing on lines that report inconsistent cleaning.
