Time-gated single-read sensing for low-maintenance online free chlorine monitoring

OneStep Technologies develops stabilized chromogenic reagent platforms for automated water analysis, with a current focus on online free chlorine monitoring. Our technology is designed to improve reagent stability, simplify operation, reduce maintenance burden, and support integration into OEM and instrument-based monitoring systems.

The platform combines stabilized single-reagent chemistry with time-gated single-read optical detection. A predefined measurement time enables routine quantitation from one absorbance reading per analytical cycle, without slope fitting, derivative calculations, or regression-window selection.

Together with reagent stability of up to 24 months under sealed storage conditions, this measurement architecture is designed to reduce routine maintenance workload and create a practical route for online chlorine monitoring in real-world operating environments — supporting reliable, machine-readable water data for operational use.

Water Data Infrastructure

From chlorine measurement to decision-ready water data

Reliable online monitoring requires more than an accurate chlorine number. It requires an analytical system that can remain practical in the field and generate data that instruments, operators, and digital systems can use with confidence.

OneStep is developing the measurement layer that connects stabilized chemistry with reliable operational data — helping turn online free chlorine monitoring into part of the broader water data infrastructure.
