The Model 740 Membrane Test System (MTS) is the first commercial instrument designed specifically for measurement of the through-thickness resistance and conductivity of ionomer and polymer electrolyte membranes. Only a small sample of bare (non-catalyzed) membrane is required, eliminating the time-consuming and costly requirement of catalyzing the membrane, and assembling and running a fuel cell. The MTS is a compact, bench-top unit and uses membrane samples that can be easily loaded with membrane compressions up to 400 psi. The environment in the closed cell can be controlled between 30 – 120°C, relative humidity (RH) from dry to 95% and pressure from 1 – 3 atm absolute. — Scribner Associates, Southern Pines, S.C.
