What is conductivity
in water? The fastest signal
that something changed.

Conductivity measures the dissolved ionic content of water. A clear explanation of what it is, what it reveals, how it is measured in microsiemens per centimetre, and why a sudden change is a powerful contamination indicator.

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.

Conductivity is how readily water carries an electrical current.

Conductivity is a measure of how easily water conducts electricity, which depends almost entirely on the amount of dissolved ions it contains. Pure water conducts poorly, but dissolved salts, minerals and other ionic substances raise conductivity in proportion to their concentration. In effect, conductivity is a fast, continuous proxy for the total dissolved ionic content of the water.

Conductivity is measured in microsiemens per centimetre, written as uS/cm. Its great strength is speed. It reacts almost instantly when dissolved content changes, which makes a sudden shift one of the most powerful early-warning signals available. A rapid change can reveal an intrusion event, a cross-connection between supplies, saline ingress at a coastal source, or chemical contamination entering the network.

  • Conductivity reflects dissolved ionic content of the water
  • Measured in microsiemens per centimetre, uS/cm
  • Responds almost instantly to a change in dissolved content
  • A sudden shift is a strong early-warning contamination signal

Conductivity questions

What does conductivity tell you about water?
Conductivity tells you how much dissolved ionic content the water carries, because dissolved salts and minerals let water conduct electricity. A higher reading means more dissolved substances. Because it tracks dissolved content so directly, conductivity is widely used as a general indicator of water composition and change.
What is conductivity measured in?
Conductivity is reported in microsiemens per centimetre, written uS/cm. Online sensors measure it continuously and stream live values to the cloud, where alert thresholds and rapid-change detection can be set to match a particular source or network.
Why is a sudden conductivity change important?
Conductivity responds almost immediately to a change in dissolved content, so a rapid shift is a strong sign that something has entered the water. It can flag an intrusion event, a cross-connection between supplies, saline ingress, or chemical contamination, often faster than other parameters react.
How is conductivity monitored in real time?
An online conductivity sensor measures the water continuously and streams readings in uS/cm to the cloud. AQUAIOT uses the SPS-EC sensor with rapid-change detection and threshold alerts, so an abnormal step is flagged in real time rather than discovered at the next scheduled sample.
