Online Chlorine Analyzers Product Description
Global Water's new CL500 continuous online chlorine analyzers are accurate and reliable instruments for free or total chlorine residual measurement.  The online residual chlorine monitors use the reliable and economical, colorimetric DPD (N,N-diethyl-p-phenylenediamine) chemistry, proven to be the most accurate method for measuring free or total residual chlorine.  With no troublesome mixing or pump components to wear out, the online chlorine analyzers provide reliable operations with minimal maintenance.

The CL500 continuous online chlorine analyzer's user selectable sample settings conserves reagents by allowing you to set the cycle time from 90 seconds up to 10 minutes.  The online residual chlorine monitor's low volume reagent and sample chamber saves on reagent costs and decreases water consumption.  A removable sample cuvette allows for simple cleaning and maintenance, and the online chlorine analyzer's viewable sample chamber allows a clear view of the sample cuvette while the instrument is sampling.

The CL500 continuous online chlorine analyzers provide a programmable 4-20 mA output signal that may be used with the GL500 datalogger for reporting purposes or to control a chemical feed system.  There are also two user-selectable Hi/Low limit relays on the online residual chlorine monitor that can trigger an AD200 autodialer or a local alarm system in the event of a system problem.  The online chlorine analyzer's small footprint and corrosion resistant NEMA 4X (IP66) enclosure allows for a simple installation that will fit in almost any space.

The CL500 continuous online chlorine analyzers come with inline pressure regulator, replacement tubing/cuvette kit (one year supply), and owners manual.
NOTE: Reagents for the online residual chlorine monitors must be purchased separately.
