Hach’s popular CL17 chlorine analyzer offers continuous monitoring of chlorine content in your sample stream. Using a colorimetric DPD chemistry method, analyzers deliver results that aren’t affected by changes in chlorine concentration, sample pH, temperature, flow or pressure. This ensures reliable, accurate measurements with minimal operator intervention. Even monthly maintenance is easy—just change the reagents and clean the colorimetric cell. It takes only 15 minutes—no special tools required.

CL17 analyzers give you the option of measuring free or total chlorine. Simply choose a unit with the respective buffer and indicator solutions. Analyzers automatically mix the solutions into your sample every 2.5 minutes, producing a red color with intensity proportional to its chlorine concentration. This photometrically measured chlorine concentration is displayed in mg/L Cl2 on the easy-to-read three-digit LCD screen.

Setup of programmable analog (4-20 mA) and alarm (relay) outputs is easy via the integral keypad. Built-in enclosure windows lets you view results, as well as reagent supply levels, without opening the protective enclosure. Compartmentalized system isolates electronic components from liquid components.

Includes: a one-month supply of reagents, sulfuric acid, installation kit, maintenance kit and user manual. Optional power cord sold separately; stock # 38060.

The CL17 has been updated to the improved CL17sc. For standard mounting, choose a model with a standpipe insulation kit. For applications with high or fluctuating pressures, choose a model with a pressure regulator installation kit.
