HACH COMPANY was established in 1947, in Ames, Iowa, USA. For more than 60 years, Hach has been the world market leader for Analytical Instrumentation for Complete Water Analysis, providing solutions for lab, process and field.


In 2002, GLI, a leading US manufacturer of process electro-chemistry analytical instruments, became part of the Hach Company family.

Water analysis has to be right. Our customers deserve complete, reliable solutions that they can be fully  confident in. Hach is your answer. We make water analysis simpler















Chlorine Analyzer, Free/Total

CLF10 sc & CLT10 sc


Chlorine Analyzer, Free/Total



Details

The CLF10 sc analyzer uses 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 insufficient sample flow. Free chlorine measurement with an amperometric analyzer, such as the CLF10 sc, does not require reagents, thus eliminating the need for routine reagent replacement and waste stream management. The CLF10sc free chlorine analyzer allows for real-time control of disinfection processes by providing continuous reading. Product includes free chlorine sensor, chlorine sensor block, sc100 controller, sc Gateway, stainless steel panel, pH flow cell and pHD sensor.

  • Exclusive Self Diagnostics
  • No Reagent Replacement, No Waste Stream
  • Real-Time Process Control
  • Compatible with Hach's "Plug and Play" Digital Controllers
  • EPA Compliant According to Method 334.0
