Online Colorimetric Analysers for Industrial and Process Water
The 3S online colorimetric analyser provides parameter-specific wet-chemistry measurement for industrial water, process streams and treated effluent. Each application is reviewed against the required chemistry, measuring range and sample matrix.
01
Industrial effluent monitoring
Industrial effluent can vary with production, cleaning and treatment activity. The 3S can support approved online methods for parameters such as sulphate, metals and other chemistry-specific measurements when the sample and range are suitable.
03
Process and treatment control
Frequent online results can help operators see changes between manual or laboratory checks and assess the effect of treatment adjustments. The analyser provides operational information; it does not replace required accredited analysis or statutory sampling.
04
Variable sample matrices
Colour, suspended solids, temperature, pH and process chemicals can affect a wet-chemistry application. PMA reviews the stream and the selected method before confirming whether the 3S configuration is appropriate.
05
Sampling and filtration
A representative, repeatable sample is essential. Challenging streams may need cooling, pressure reduction, settling or filtration before analysis, with the conditioning system selected around the site conditions. Use the online analyser sample-conditioning guide to structure the review.
06
Supporting operational and compliance programmes
The 3S can provide routine online information within a wider monitoring programme. Permit requirements, approved methods, reporting obligations and laboratory checks remain application-specific and should be confirmed separately.
INDUSTRIAL APPLICATION REVIEW
Define the stream before selecting the analyser
A reliable proposal starts with the analyte, process stage, expected range, sample matrix, conditioning needs and intended use of the data.
01.
Analyte and process
Identify the parameter and the process conditions that can change its concentration.
02.
Sampling point
Choose a point that provides a representative and safely accessible sample.
03.
Expected range
Confirm normal, low and high concentrations against the selected analytical method.
04.
Sample matrix
Provide details of colour, solids, pH, temperature and likely chemical interferences.
05.
Conditioning
Establish whether cooling, pressure control, settling or filtration is needed.
06.
Use of the result
Define whether the measurement will support process control, trend review or a wider compliance programme.
Industrial sample details matter
Process changes and interfering substances can affect method suitability. The application review should include the operating cycle, sample hazards and required installation protection.
Two sample streams
The general 3S-CL platform supports two measurable sample streams where the application is suitable.
Method dependent
Measuring range, analysis time and reagent use depend on the selected chemistry.
Installation conditions
The analyser is designed for indoor installation; suitable protection is required for outdoor or harsh locations.
Laboratory programme
Required accredited analysis and statutory sampling continue alongside online operational monitoring.

Where industrial users apply online wet chemistry
Suitable applications can sit within process control, water treatment and treated-effluent monitoring.
Chemical and process manufacturing
Online measurement can support selected process and treatment parameters where the method matches the stream.

Industrial water treatment
Operators can use routine analytical information to review influent, treatment-stage and final-water conditions.
Treated effluent
Approved parameter-specific methods can support a broader monitoring programme when matrix effects and conditioning are addressed.
Online results support decisions; they do not replace required compliance analysis
Permit conditions, approved methods, statutory samples and accredited laboratory work remain controlling requirements where applicable.
