Online Colorimetric Analyser Applications for Water Treatment
The 3S online colorimetric analyser is designed for parameter-specific wet-chemistry measurement across water treatment and process monitoring. It is configured around the required chemistry, concentration range and sample conditions.
01
Drinking-water treatment
Routine analysis of treatment parameters and residuals can help operators build a clearer picture of water-treatment performance.
02
Municipal and industrial wastewater
Wastewater applications require careful consideration of suspended solids, colour and changing sample chemistry. Application review can include ammonia, nitrate, phosphate and sample conditioning.
03
Boiler, condensate and cooling water
Water chemistry is important across boilers, steam cycles and high-purity water systems.
04
Industrial and process water
Industrial streams can involve variable matrices, treatment stages and effluent-monitoring needs.
05
Flexible sampling and analyser configuration
A repeatable analyser-led routine can reduce variation caused by different manual testing, timing and recording practices. The general 3S-CL platform supports two measurable sample streams. Selected compatible analytical methods can also be combined in dual-parameter configurations, with suitability confirmed during application review.
06
Supporting routine process control
The 3S can support process and compliance-monitoring programmes by providing more frequent online analytical information between manual or laboratory checks. It does not replace accredited laboratory analysis, statutory sampling or application-specific compliance instruments where those are required.

APPLICATION REVIEW
Understand the application limits
Suitability depends on the analytical method, measuring range, sample matrix, installation and required analysis frequency.
01.
Parameter
The 3S uses parameter-specific analytical chemistry.
02.
Measuring range
Measuring range depends on the selected method.
03.
Analysis time
Analysis time depends on the selected chemistry.
04.
Reagent use
Reagent consumption varies by parameter and frequency.
05.
Sample condition
Sample colour and suspended solids must be considered.
06.
Filtration
Filtration may be required for challenging samples.
Application details matter
Outdoor installation requires suitable protection, and accredited laboratory analysis remains necessary where required.
2 samples
The general platform supports two measurable sample streams.
Parameter dependent
Measuring range and analysis time depend on the selected chemistry.
IP54
Designed for indoor installation; suitable protection is required outdoors.
Laboratory checks
Online analysis does not replace required accredited laboratory work.
Application review details
Confirm the selected analytical method and site conditions before specification.
| Parameter | Selected analytical chemistry |
| Measuring range | Method specific |
| Sample matrix | Colour and solids considered |
| Analysis time | Parameter dependent |
| Reagent use | Varies by parameter and frequency |

Current parameter-specific documentation should be confirmed with PMA before procurement.
Where the 3S fits
The analyser can provide routine online information across suitable water-treatment and industrial process applications.
Drinking water
Selected metals, nutrients and treatment residuals can be monitored where the approved method matches the sample and range.
Wastewater
Selected wet-chemistry measurements can be supported where solids, colour and sample conditioning have been considered.
Process water
Configurable analysis supports suitable boiler, cooling and industrial process-water applications.
Online analysis supports, but does not replace, required laboratory work
Accredited laboratory analysis, statutory sampling and application-specific compliance instruments remain necessary where required.
