The Multisensor MS1210-S is a medium-range online oil-in-water and VOC analyzer that measures hydrocarbons and volatile organic compounds in water from 0.1 to 40 ppm. It is used to monitor industrial effluent, cooling water, drains and process water, and like all Multisensor analyzers it measures from the headspace without touching the water and without reagents. Akan Industrial and Automation supplies and commissions the MS1210-S in Türkiye as Multisensor Systems dealer.
Why monitor industrial effluent for VOCs?
Fuels, solvents and other volatile organics reach wastewater through leaks, spills and overloaded pre-treatment. A non-compliant discharge can lead to fines, process contamination and reputational damage, and authorities may then require continuous monitoring. The MS1210-S provides that monitoring at the outlet, raising an alarm as soon as concentrations start to rise so that valves can be closed or the flow diverted.
How does it work?
Water flows through a stainless steel sampling tank. Volatile compounds move into the headspace above the water, and this gas is passed across an electronic-nose sensor array. The sensor never contacts the water, so there is no fouling and no cleaning between services. The analyzer is calibrated with a toluene standard and reports total VOCs; bespoke calibration for a specific compound is available.
What can it detect?
- Fuels and oils, including diesel and kerosene
- BTEX and styrene
- PAHs
- Chlorinated solvents: TCE, PCE, vinyl chloride, 1,2-dichloroethane, 1,1,1-trichloroethane and 1,1-dichloroethylene
