Hach CL10 sc reagentless chlorine analyser

The CL10 sc reagentless chlorine analyser allows for real-time control of disinfection processes by providing continuous readings that indicate when treatment conditions have changed. A measurement range from 0–20 ppm with an resolution of 0.001 ppm ensures process control in a wide range of disinfection applications.

The analyser uses Hach’s Cal Watch self-diagnostics to alert users when the process has changed or the instrument needs servicing. Diagnostic features include warning of pH and chlorine calibration deviation and a non-contacting flow sensor for notification of insufficient sample flow. Free or total chlorine measurement with an amperometric analyser, such as the CL10 sc, does not require reagents, thus eliminating the need for routine reagent replacement and waste stream management.

The analyser can be used with any Hach sc digital controller without software configuration. Power supply is 12 VDC 30 mA maximum, supplied by the controller. It can be mounted on a flat, vertical surface (such as a wall, panel or stand) and requires a sample flow rate of 30–50 L/h (optimum is 40 L/h).
