Hydrogen generators are designed to produce hydrogen gas at a purity of 99.9995% or greater. The hydrogen gas is produced by electrolytic dissociation of water before passing through a desiccant cartridge. Safety features include low-water audible alarms to indicate when the reservoir needs to be refilled and automatic shutdown to protect the equipment. Our generators eliminate dangerous gas cylinders from the lab and produce a continuous or on-demand supply of pure hydrogen. Low-maintenance systems eliminate inconvenient extended downtime.
