Water and Wastewater Analysis
Digital meters support process control from raw-water intake through clarification, biological treatment, disinfection and final discharge.
Why digital measurement matters
pH and ORP help operators understand chemical condition and oxidation-reduction environment. Conductivity and TDS show dissolved ionic loading. Dissolved oxygen is central to aeration control and biological process health. Turbidity supports clarification and filtration monitoring. Online instruments provide continuous trend visibility, while portable meters help verify individual tanks, outlets and field locations.
Recommended measurement workflow
- Define the decision the result must support.
- Identify the parameter, expected range and required resolution.
- Select a suitable meter, sensor and calibration standard.
- Collect a representative sample or confirm the online installation point.
- Calibrate, rinse and condition the sensor according to the manual.
- Allow the reading to stabilise and record temperature and calibration status.
- Investigate unexpected trends and confirm critical results when necessary.
Sampling
Use clean containers and representative locations. Avoid aeration or contamination where it could change the parameter.
Calibration
Use fresh standards, appropriate calibration points and a frequency suitable for the importance and stability of the measurement.
Maintenance
Clean sensors carefully, store them correctly and replace consumable membranes, electrolytes or electrodes when performance declines.
