A compact 3S analyser for hardness monitoring in treated water, ion exchange and boiler-water applications.
Use an online hardness trend to see changes between sample checks and investigate treatment breakthrough. Start by defining the hardness measurement your process needs, the reporting units and the concentration at which operators should respond.
Confirm whether calcium hardness or total hardness is required. The published calcium method should not be assumed to represent calcium and magnesium together in every water matrix.
Review treated-water quality at a representative point and set alarms appropriate to the process.
Bring the required hardness measurement together with sample conditioning and the wider water-quality checks.
Use a suitable sampling point to investigate feed or treated-water conditions alongside laboratory measurements.
The manufacturer describes a calcium-based colorimetric method: calcium reacts with a complexing reagent to form a violet colour. Results are reported as calcium carbonate, CaCO3.
The 3S-CL runs batch analyses at a programmable frequency. Automatic calibration, validation and cleaning can be scheduled, and the analyser separates its wet section from the electronics.
Agree the required range, cycle time and plant outputs when specifying the instrument. The manufacturer documentation gives the options and installation requirements for the selected configuration.
Send PMA the sample source, expected concentrations and available laboratory results. Include temperature, pressure, solids and any constituents that may affect the analysis.
We will review sample delivery, filtration or dilution where needed, drainage, reagent storage and service access. Include the required signals and alarm response so the measurement can be used by your operating team.
PMA helps you bring the analyser, sample system and site requirements together. Talk to our team about selection, commissioning, reagent supply and support for your installation.
The published 3S method measures calcium and reports hardness as CaCO3. If your specification requires total hardness, including magnesium, ask PMA to confirm the suitable method and configuration for that requirement.
Speak to the PMA team about your instruments, reagents or service requirements. Tell us what you need, and we’ll help you find the right next step.
