Chlorine Analyzer
Bufferless Amperometric Chlorine Analyzer

The Foxcroft FX-1000P-B Bufferless Chlorine Residual Analyzer is environmentally friendly, requiring absolutely no chemicals or reagents.

Designed to operate continuously for years in typical process environments, the FX-1000P-B reagentless chlorine analyzer utilizes the most accurate online test method to determine Free chlorine residual levels in potable water, similar to that used in lab environment titrator test methods.

Residual readings are instantaneous and do not rely on sample and hold methods; making it an excellent choice for your chlorine control or monitoring applications. The continuous 4-20 milliamp output signal can be used to drive chlorine residual, trigger an autodialer in remote or off-hour situations, or communicate with a SCADA system.

The measuring cell design incorporates several features to ensure accurate readings. Features include; high-grade bare gold and copper electrodes rather than a membrane that can foul or clog, fixed sample rates and continuous cell mixing and cleaning. Solid-state analog electronics provide stable, drift free, residual readings and output signals. Electronic isolation eliminates problems from ground-loop and ensures operator safety.
