Automated colourimetric measurement for water and wastewater monitoring, with programmable analysis, straightforward operation and efficient reagent use.
The 3S provides online measurement of water quality parameters such as phosphate, ammonia and iron. Its compact cabinet brings together programmable analysis, touchscreen control and reagent management for use across water, wastewater and industrial processes.
Set the analysis frequency to suit your monitoring process.
Support two sample streams in one compact analyser.
Access operation and measurement information from the colour display.
The 3S combines a small footprint with serviceable consumables and programmable functions. Its design keeps the analysis process easy to follow while supporting unattended monitoring.
From sample handling and reagent access to commissioning and ongoing service, PMA can help you assess how the 3S fits your monitoring point. Tell us about the parameter, water matrix and operating conditions so our team can discuss a suitable arrangement.
Available measurements depend on the selected method and your process. These examples show where online colorimetry may be useful; PMA can confirm the right configuration for your site.
