Hach’s answer to reagentless amperometric chlorine measurement.
From the leaders in disinfection monitoring, the right instrument for reagentless chlorine analysis.
Exclusive Self Diagnostics
The CLF10 sc and CLT10 sc analyzers leverage Hach’s exclusive self diagnostics to alert users when the process has changed or the instrument needs servicing. Diagnostic features include the Cal Watch algorithm for warning of pH and chlorine calibration deviation and a non-contacting flow sensor for notification of insu=cient sample flow.
Real-Time Process Control
The CLF10 sc and CLT10 sc analyzers allow for real-time control of disinfection processes by providing continuous readings that indicate when treatment conditions have
changed.
No Reagent Replacement, No Waste Stream
Chlorine measurement with an amperometric analyzer such as the CLF10 sc or CLT10 sc does not require reagents, eliminating the need for routine reagent replacement and waste stream management.
Compatible with Hach’s “Plug and Play” Digital Controllers
The CLF10 sc and CLT10 sc analyzers can be used with any Hach sc digital controller. Just plug in the analyzer and it’s ready to use without software configuration.
EPA Compliant According to Method 334.0
The CL10 sc and CLT10 sc analyzers can be used for reporting chlorine residual measurements in accordance with EPA Method 334.0.
