Demanding processes can have a harsh impact on instrument corrosion or optics contamination. With preventative maintenance driven by ISM, easy parts exchange can be done on your schedule.
Multi-Gas Analyzers
Process TDL Gas Analyzers for Measuring Multiple Gases Simultaneously
A multi-gas analyzer is an analytical device that can simultaneously measure the concentration of up to two gases within a gas mixture using laser absorption spectrometry. Muti-gas analyzers from our GPro® 500 range measure continuously and in situ, providing reliable and accurate results in various critical applications. They have been expertly designed so you can enjoy faster measurements, improved process availability, and unparalleled ease of use.
