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.

A small pH drift is a large operational signal.

pH sits at the centre of water chemistry. It governs corrosion of pipes and fittings, the effectiveness of disinfection, and the behaviour of metals like iron and manganese that drive discolouration. For drinking water the optimal range is roughly 6.5 to 9.5, and sustained movement outside it points to treatment failure, infrastructure issues or contamination upstream.

AQUAIOT monitors pH continuously with the SPS-pH sensor, streaming timestamped readings to the cloud and alerting your team the moment a trend leaves your defined band. Because pH is logged alongside chlorine, ORP and turbidity, you can see not just that it moved but what moved with it, turning an isolated reading into a diagnosis.

  • Continuous acidity and alkalinity profiling, fully timestamped
  • Alerts when pH trends outside your defined operating band
  • Early indicator of corrosion risk and treatment performance drift
  • Logged alongside chlorine and ORP for faster root-cause analysis

pH monitoring questions

What is the ideal pH for drinking water?
Drinking water is generally maintained within a pH of roughly 6.5 to 9.5. Values drifting outside this band can indicate treatment problems or corrosion risk. Continuous monitoring lets you set tighter operational alerts so you act on trends long before a regulatory limit is approached.
Why does pH matter operationally?
pH influences corrosion of pipework and fittings, the efficiency of chlorine disinfection, and the release of metals such as iron and manganese that cause discolouration. Stable pH protects infrastructure and water quality at the same time.
How quickly are pH changes detected?
Continuously. The SPS-pH sensor streams real-time data over cellular or LoRaWAN telemetry, and threshold breaches trigger immediate SMS, email or app alerts with role-based routing.
Can pH be monitored with other parameters?
Yes, and it usually should be. AQUAIOT logs pH alongside chlorine, ORP, turbidity and conductivity so a pH shift can be interpreted in context, which makes root-cause analysis far faster.
