The MultiExact 4100 is a high-performance multi-gas analyser designed to provide up to four simultaneous gas stream measurements including: oxygen (O2), carbon dioxide (CO2), carbon monoxide (CO), nitrous oxide (N2O), methane (CH4) and moisture (H2O).

Specifically designed to address the needs of industrial and medical gas manufacturers, the MultiExact 4100 can provide up to four simultaneous gas stream measurements including: O2 (trace, control, and purity), CO2, CO (% and trace), N2O, and CH4 (trace).

It can be fitted with a wide range of sensing technologies – Paramagnetic, Zirconia, Gas Filter Correlation (Gfx), Infrared, and Aluminium Oxide. These proven, digital sensors not only provide highly accurate measurements but also offer operational flexibility in a range of industries and applications.

The non-depleting, high-stability sensing technologies help extend maintenance intervals while intelligent functionality such as independent auto-calibration helps to deliver operational efficiencies over a long product life.
