Example readings for illustration purposes

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 safety depends on chemistry held in balance.

Pool water safety rests on three linked parameters. Free chlorine provides disinfection, pH governs how effective that chlorine actually is, and ORP measures the true disinfecting power that ties them together. When these are checked by periodic manual testing, the chemistry can drift between tests, leaving a window where disinfection is weaker than the operating team believes.

AQUAIOT monitors pool water continuously. The SPS-CI-C sensor tracks free chlorine, the SPS-pH sensor tracks pH, and the SPS-ORP sensor confirms disinfection is genuinely working, not just dosed. Readings stream to role-based dashboards with threshold alarms, so the operating team holds water inside its safe window across the day and keeps an exportable record behind every reading.

  • Continuous free chlorine, pH and ORP on pool water
  • ORP confirms disinfection is effective, not just dosed
  • Threshold alarms when chemistry drifts outside the safe window
  • Audit-ready, exportable records for the operating team

Pool water quality monitoring questions

Which parameters define pool water safety?
Free chlorine for disinfection, pH because it governs how effective that chlorine is, and ORP as the direct measure of disinfecting power that links the two. AQUAIOT monitors all three continuously with the SPS-CI-C, SPS-pH and SPS-ORP sensors.
Why monitor ORP as well as chlorine?
Chlorine dose alone does not tell you whether disinfection is working, because pH and demand change its effectiveness. ORP measures the actual disinfecting power, so a falling ORP flags weakening disinfection even when the chlorine reading looks acceptable.
Does it replace our manual pool testing?
Operational testing regimes still apply and the operator retains responsibility for pool safety. Continuous monitoring closes the gaps between manual tests, catches drift in real time, and provides timestamped, exportable records behind the duty holder’s controls.
Is installation disruptive to a working plant room?
AQUAIOT favours retrofit-friendly sensors suitable for live pool plant. UK engineers handle the survey, install and commissioning, with over-the-air configuration afterwards to reduce repeat visits.

Keep pool water inside
its safe window.
