Continuous chlorine monitoring.
Catch residual loss before
it becomes a risk.
Real-time free and total chlorine measurement across treatment, distribution and storage. Know the moment disinfection residual drifts toward the microbial risk threshold, not days later from a grab sample.
Example readings for illustration purposes
What you can’t see
is already costing you.
Issues are flagged after damage is done, not before it starts. Every delayed alert is a cost you didn’t have to carry.
Manual records, missed checks, and audit gaps across sites. When an inspector asks for evidence, the scramble begins.
pH, chlorine, or turbidity can shift for days or weeks before anyone notices. Without real-time monitoring, you’re always reacting.
Continuous monitoring.
Instant alerts. Full audit trail.
Three connected layers that turn raw sensor data into actionable intelligence, automatically.
Connected sensors stream real-time data across all parameters, 24 hours a day. Cellular and LoRaWAN telemetry with encrypted payloads.
Threshold breaches trigger instant SMS, email, or app notifications. Escalation rules and role-based routing ensure the right person acts.
Cloud dashboards give your team the data, trendlines, and records they need, instantly. Every reading logged, every action auditable.
Chlorine, in context.
Every parameter alongside it.
Chlorine never tells the whole story alone. AQUAIOT measures it alongside pH, turbidity, ORP and the full sensor range, so you see disinfection performance in context.
Continuous acidity and alkalinity monitoring. Detect corrosion risk, Legionella-risk conditions, and treatment performance drift.
Detect particulate contamination, filter breakthrough, and process upsets in real time.
Continuous disinfection residual monitoring. Ensure treatment efficacy without manual sampling delays.
Monitor oxygen levels critical for biological process control, aeration efficiency, and environmental compliance.
Track dissolved mineral content and detect contamination events, cross-connections, or treatment changes in real time.
Specsens UV-Vis sensing at the edge. Detect organic load, humic substances, and complex contamination signatures beyond single-parameter sensors.
Detect apparent and true colour changes that may indicate natural organic matter, iron, manganese, or treatment by-products.
Oxidation-reduction potential monitoring for disinfection effectiveness, redox conditions, and process control in treatment and distribution.

Free chlorine is the active disinfectant protecting water through treatment and distribution. When the residual falls, microbial risk rises, and below roughly 0.1 mg/L that protection is effectively gone. Manual sampling captures a single moment, but residual decays continuously with temperature, demand, retention time and pipe condition, so the dangerous drift usually happens between visits.
AQUAIOT measures free and total chlorine continuously with the SPS-CI-C sensor and the dedicated SPA Chlorine Analyzer. Readings stream to the cloud over encrypted telemetry, and the moment a residual approaches a low threshold the system alerts your team by SMS, email or app, with escalation rules so disinfection failures are caught and recorded before they reach consumers.
- Continuous free and total chlorine, no manual sampling delay
- Threshold alerts before residual drops into the microbial risk zone
- Track residual decay across distribution zones and storage
- Audit-ready records of disinfection performance, generated automatically
