Mettler-Toledo's InLab sensors measure pH in harsh chemical processes — glass membranes selective to H+ ions. Every titration, every yield calculation in every chem lab: our instruments underpin the numbers.

Plug Power's PEM electrolyzers split water into H2 and O2 using renewable electricity. The proton-exchange membrane (Nafion) is the chemistry at the core — perfluorinated sulfonic acid conducting protons while rejecting electrons.

Ashta's membrane cell electrolysis splits brine into chlorine, caustic soda, and hydrogen — the foundational chemistry for PVC, polyurethane, water treatment, and a thousand downstream products. The chlor-alkali triangle feeds the chemical industry.
