Water Quality Monitoring System

Types

• pH: online, high-temperature, antimony and digital pH sensors with panel or field meters, plus ORP.
• Dissolved Oxygen: polarographic and optical luminescence sensors from ppb boiler water levels to mg/L in aeration tanks.
• Conductivity: titanium-cell, four-electrode and inductive sensors for ultra-pure water through to strong acids.
• Chlorine: residual chlorine sensors and meters for drinking water, pools and disinfection.
• Ion: ion selective electrodes and meters for fluoride, chloride, nitrate, ammonia nitrogen and calcium.
• Turbidity/Total Suspended Solids: low and high range turbidity sensors and in-situ TSS sensors with self-cleaning wipers.
• Industrial Water Analyzer: reagent-based online analysers for ammonia nitrogen, total nitrogen, total phosphorus, cyanide, chromium, copper, iron, manganese, nickel and zinc.
• Portable Water Analyzer: handheld pH, conductivity and dissolved oxygen meters for spot checks.

Applications

• Sewage and wastewater treatment plants
• Industrial effluent and heavy metal monitoring
• Drinking water treatment and distribution
• Thermal power plant boiler feed water and condensate
• Pure and high-purity water systems
• Chemical and fertiliser production
• Flue gas desulphurisation
• Aquaculture and river monitoring

How to choose

• List the parameters your process or discharge licence requires.
• Match the sensor to the medium: pure water, wastewater, high temperature or corrosive.
• Decide between continuous online monitoring and portable spot checks.
• Check outputs for your control system: 4–20 mA, relays or RS485 Modbus RTU.

For treatment plants and industrial sites across Malaysia, LKS handles installation, calibration, commissioning and SCADA integration of water quality instruments. Contact our engineers to plan a monitoring system or request a quotation.
