Kemio Sensors Chlorine HR Free Chlorine 0-25 mg/l Total Chlorine 0-500 mg/l

The Kemio® High‑Range (HR) Chlorine Sensors are single-use electrochemical sensors compatible with Kemio Disinfection or Kemio Multi meters. Designed for chlorine-demanding applications, they accurately measure Free Chlorine (0.1–25 mg/L) and Total Chlorine (1–500 mg/L) in 60 seconds. Each sealed sensor includes a unique barcode for automatic test verification and digital traceability. Ideal for use in water treatment, hospitality, aquaculture, food & beverage, and industrial hygiene, these sensors deliver consistent, lab-quality results even in turbid or coloured waters. Packed with 100 individually foil-wrapped units and a calibration chip, the HR sensors simplify compliance and streamline field testing.
