SICK MCS300P | Extractive Gas Analysers For Simultaneous Process Monitoring
Extractive Gas Analysers
SICK MCS300P
Simultaneous process monitoring of up to 6 measuring components
The MCS300P is an extractive gas analyser manufactured by SICK which is used for the simultaneous process monitoring of up to six measuring components. It is an extractive process photometer for measuring gaseous or liquid media.
SICK MCS300P measures IR and VIS active components with variable measuring ranges from very low (ppm) to high (vol%) concentrations. For monitoring of toxic or flammable mixtures, it has special process cells with safety devices like twinseals and flushing gas feeds.
The heatable cells made of corrosion-resistant materials have a high pressure resistance.
Automatic adjustment, innovative operation concept and modern communication protocols make the SICK MCS300P an all-purpose photometer, even for potentially explosive atmospheres.
Typical Applications for SICK MCS300P Gas Analysers
- Process monitoring in production of vinyl chloride or isocyanate
- Process control in the chemical industry
- Process monitoring in the production of plastics
- Monitoring of exhaust gas purification plants
- Determination of the water content of solvents
