Why disinfectant and inhibitor testing matters
Testing disinfectants and inhibitors is essential to verify the concentration of agents used to control microbial growth and corrosion in water systems; it helps ensure safe operation without over‑ or under‑dosing. Common disinfectants include free and total chlorine, chlorine dioxide, bromine and hydrogen peroxide; inhibitors protect assets from corrosion and scale deposition. Routine monitoring supports compliance and keeps systems efficient.
Supporting system hygiene, corrosion control & regulatory compliance
Accurate measurement of disinfectant residuals underpins Legionella risk management and water hygiene programmes in healthcare, commercial and industrial buildings; appropriate inhibitor levels help protect metal surfaces and extend plant life. Our reporting supports maintenance planning and remedial actions with clear interpretation notes.
