Swimming pool water monitoring.
Bather safety, measured
continuously.

Continuous swimming pool water quality monitoring for leisure sites. Track free chlorine, pH and ORP in real time so disinfection and balance are right while the pool is in use, not only at the next manual test.

What you can’t see
is already costing you.

Reactive call-outs

Issues are flagged after damage is done, not before it starts. Every delayed alert is a cost you didn’t have to carry.

Fragmented compliance

Manual records, missed checks, and audit gaps across sites. When an inspector asks for evidence, the scramble begins.

Hidden drift

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.

1. Monitor

Connected sensors stream real-time data across all parameters, 24 hours a day. Cellular and LoRaWAN telemetry with encrypted payloads.

2. Alert

Threshold breaches trigger instant SMS, email, or app notifications. Escalation rules and role-based routing ensure the right person acts.

3. Respond

Cloud dashboards give your team the data, trendlines, and records they need, instantly. Every reading logged, every action auditable.

Every parameter.
One connected system.

From standard chemistry to full-spectrum UV-Vis sensing, AQUAIOT covers every dimension of water quality your operation demands.

SPS-pH Water Quality Sensor
pH
SPS-pH Sensor

Continuous acidity and alkalinity monitoring. Detect corrosion risk, Legionella-risk conditions, and treatment performance drift.

Optimal drinking water pH: 6.5–9.5. Drift outside this range signals treatment failure or infrastructure issues.
SPS-T-SC1 Turbidity Sensor
Turbidity & Suspended Solids
SPS-T-SC1 Sensor

Detect particulate contamination, filter breakthrough, and process upsets in real time.

Turbidity spikes are often the first indicator of pipe disturbance, contamination ingress, or treatment failure.
SPS-CI Free Chlorine Sensor
Free Chlorine
SPS-CI-C Sensor

Continuous disinfection residual monitoring. Ensure treatment efficacy without manual sampling delays.

Chlorine residual below 0.1 mg/L creates microbial risk. Continuous monitoring catches drops before they become incidents.
SPS-DO Dissolved Oxygen Sensor
Dissolved Oxygen
SPS-DO Sensor

Monitor oxygen levels critical for biological process control, aeration efficiency, and environmental compliance.

Low DO in wastewater systems indicates biological stress; in distribution it can indicate contamination ingress.
SPS-EC Conductivity Sensor
Conductivity
SPS-EC Sensor

Track dissolved mineral content and detect contamination events, cross-connections, or treatment changes in real time.

Sudden conductivity changes are a rapid indicator of intrusion, saline ingress, or chemical contamination.
SPS-F Full Spectrum Water Quality Sensor
Full-Spectrum UV-Vis
SPS-F SpecSens Sensor

Specsens UV-Vis sensing at the edge. Detect organic load, humic substances, and complex contamination signatures beyond single-parameter sensors.

Full-spectrum sensing captures richer water quality signatures, ideal for source water characterisation and treatment optimisation.
SPS-Color-C Colour Sensor
Colour
SPS-Color-C Sensor

Detect apparent and true colour changes that may indicate natural organic matter, iron, manganese, or treatment by-products.

Colour is a key aesthetic and compliance parameter, continuous monitoring prevents visible discolouration events reaching consumers.
SPS-ORP Water Quality Sensor
ORP
SPS-ORP Sensor

Oxidation-reduction potential monitoring for disinfection effectiveness, redox conditions, and process control in treatment and distribution.

ORP is a direct measure of disinfection power, falling ORP values indicate that treatment residual is being depleted.

Pool water changes with every bather. Manual tests cannot keep up.

Swimming pool water quality moves constantly as bather load, temperature and dosing change through the day. Free chlorine has to stay in range to keep disinfection effective, pH governs both bather comfort and how well that chlorine works, and ORP reflects the genuine disinfecting power of the water. Manual pool tests capture single moments, but the conditions that matter for bather safety shift continuously between them.

AQUAIOT monitors pool water continuously across these three parameters. Free chlorine on the SPS-CI-C confirms disinfection residual, pH on the SPS-pH holds the balance that keeps chlorine effective and bathers comfortable, and ORP on the SPS-ORP shows whether disinfection is genuinely working. Readings stream to the cloud with threshold alerts, so leisure operators are warned the moment water drifts out of range and hold an exportable record of pool condition. The pool operator retains responsibility for pool water management.

  • Continuous free chlorine, pH and ORP while the pool is in use
  • ORP confirms disinfection power, not just chlorine dose
  • Real-time alerts when water drifts out of range
  • Exportable record of pool water condition

Pool water monitoring questions

Which parameters matter for pool water?
Free chlorine keeps disinfection effective, pH governs bather comfort and how well chlorine works, and ORP reflects the genuine disinfecting power of the water. AQUAIOT monitors all three continuously on the SPS-CI-C, SPS-pH and SPS-ORP.
Why monitor ORP as well as chlorine in a pool?
Chlorine tells you how much disinfectant is present, ORP tells you how much disinfecting power it is actually delivering. Reading them together confirms disinfection is genuinely effective as bather load and pH change through the day.
Does this replace manual pool testing?
It complements it. Continuous monitoring catches the drift between manual tests and alerts operators in real time. The pool operator retains responsibility for pool water management, and AQUAIOT supplies the continuous data and records.
How are operators alerted?
Threshold alerts fire by SMS, email or app with role-based routing, so the right member of the leisure team is warned the moment free chlorine, pH or ORP drifts out of range.
