Application Note: Leak Detection With pH

Virtually all industries from food and beverage to chemical processing use heat exchangers, condensers, or jacketed vessels.

Leakage of the process into the cooling water represents a loss of product and can be a source of fouling or corrosion in the cooling water system.

Conversely, leakage of the cooling water into the process can be a source of contamination. An example is the leakage of cooling water into steam condensate, which is a source of contamination in the steam-water circuit.
