The exact device specifications and performance data of the product may deviate from the information provided here, and depend on the application in which the product is being used and the relevant customer specifications.


The MCS300P is an extractive process photometer for measuring gaseous or liquid media. It measures IR- and VIS-active components with variable measuring ranges from very low (ppm) to high (vol%) concentrations. For monitoring toxic or flammable mixtures, it features special process cells with integrated protective devices, such as double seals and purge gas chambers on both sides. The heatable cells made of corrosion-resistant materials have a high pressure resistance. An automatic adjustment device, a sophisticated operating concept and modern communication protocols make the MCS300P a versatile photometer, even for explosion-hazardous areas.
