Water Quality Parameters
Explore our comprehensive resource hub for water quality parameters.
Learn measurement principles, applications, related parameters, and solutions for accurate water quality monitoring.
Core Water Quality Parameters
Essential parameters for water quality monitoring and process control.
pH
Measure the acidity or alkalinity of water to support process control, treatment efficiency, and regulatory compliance.
ORP
Measure oxidation-reduction potential to evaluate disinfectant activity, oxidation processes, and overall water chemistry.
Conductivity
Measure water’s ability to conduct electricity to estimate dissolved ionic concentration and process conditions.
Dissolved Oxygen
Measure dissolved oxygen levels to assess biological activity, aeration efficiency, and aquatic ecosystem health.
Turbidity
Measure suspended particles that reduce water clarity and indicate filtration or treatment performance.
Chlorine
Monitor chlorine concentration to verify disinfection performance and maintain safe drinking and process water.
Supporting Water Quality Parameters
Important parameters that provide additional insights into water quality.
Temperature
Measure water temperature to support process control and improve the accuracy of other water quality measurements.
TDS
(Total Dissolved Solids) Estimate the concentration of dissolved solids in water using conductivity-based measurements.
Salinity
Measure dissolved salt concentration for environmental monitoring, aquaculture, desalination, and industrial processes.
Resistivity
Measure water’s electrical resistance to evaluate ultrapure water quality and ionic contamination.
UVT
(UV Transmittance) Measure ultraviolet light transmission to evaluate UV disinfection efficiency and water optical quality.
Chlorine Species
Different forms of chlorine used in water treatment and disinfection.
Residual Chlorine
Measure the chlorine remaining after treatment to ensure continued protection throughout the distribution system.
Total Chlorine
Measure the combined concentration of free and combined chlorine to evaluate overall disinfectant levels.
Combined Chlorine
Measure chlorine that has reacted with ammonia or organic compounds, reducing disinfection effectiveness.
Free Chlorine
Measure the active disinfecting chlorine available for effective microbial control in water systems.
Measurement Processes
Essential processes for accurate water quality measurement.
Temperature Compensation
Correct measurement results for temperature effects to improve the accuracy and consistency of analytical sensors.
pH Calibration
Calibrate pH sensors with reference buffer solutions to ensure accurate and reliable pH measurements.
DO Calibration
Calibrate dissolved oxygen sensors to maintain accurate oxygen measurements under changing environmental and process conditions.
Sensor Cleaning
Remove fouling, deposits, and contaminants to maintain sensor accuracy, response time, and long-term performance.
Sensor Maintenance
Inspect, service, and maintain sensors regularly to ensure reliable operation and extend their service life.
Sensor Verification
Verify sensor performance against known reference values to confirm measurement accuracy before routine operation.
