Residual Analyzers

Severn Trent Services has been a leader in continuous chlorine residual analysis for over twenty years. Using proven amperometric technology, Severn Trent Services has a complete offering of chlorine analyzers, which provide accurate residual analysis for a wide range of monitoring and control applications.

Our offering of residual analyzers are designed to continuously monitor free or total chlorine or other oxidants in drinking water, wastewater, cooling water and other process water applications.

The Capital Controls® Series 1870E Chlorine Residual Analyzer is an amperometric-based instrument designed to continuously analyze free or total chlorine, chlorine dioxide, iodine, bromine or other oxidants.

The Capital Controls® Series 1770 Chlorine Analyzer works on the same principle as the 1870E but is designed for use with clean, stable pH waters. The system is a reagentless, amperometric analyzer designed for the continuous measurement of free chlorine.

The Capital Controls® CL500 residual analyzer is designed to continuously monitor free or total chlorine or other oxidants. Auto ranging to 20 mg/l. The amperometric analyzer is EPA approved for on-line chlorine residual monitoring in drinking water.

The Capital Controls® CL1000 residual analyzer is designed to continuously analyze free or total chlorine and other oxidants. Auto ranging to 60 mg/l. The amperometric analyzer is EPA approved for on-line chlorine residual monitoring in drinking water.

The Capital Controls® CL1000B residual analyzer is designed to continuously analyze free chlorine and other oxidants. The bufferless system uses a unique 3-electrode measuring cell arrangement that enables it to measure in the parts per billion (ppb) residual range, as well as high residual ranges. Auto ranging to 60 mg/l. The amperometric analyzer is EPA approved for on-line chlorine residual monitoring in drinking water.

The Bufferless Residual Monitor Dual Validation Unit (DVU) incorporates two independent CL1000B bufferless residual analyzers. The control analyzer can be used to set the residual dose while the police analyzer validates the result.

The MicroChem®2 Analyzer is a three-channel system to measure free and total chlorine, chlorine dioxide and ozone.

The MicroDPD® on-line colorimeter chlorine residual analyzer uses proven DPD colorimetric technology for monitoring chlorine in both municipal and industrial applications. This instrument is ideal for accurately monitoring and controlling free and total chlorine residuals up to 10 ppm.
