Scribner 740 Membrane Test System
The 740 MTS is perfectly designed for the creation of new ionomers and solid electrolytes, providing quick and precise evaluations of membrane resistance and conductivity changes across various temperatures, humidity levels, and pressures. It streamlines the process by removing the need to catalyze a membrane and construct a fuel cell for assessing ionomer effectiveness.
