Solve gas supply instability in leak tests

This equipment can generate a hydrogen-nitrogen mixed gas just by supplying purified water. Capable of generating trace gases that comply with international standards in a safe and affordable manner.

No gas cylinder required, thus reducing cost

No frequent purchase of gas cylinders is necessary, eliminating what was a significant burden in conventional leak tests. Accordingly, running costs can be reduced to approximately one-quarter of that of tests that use helium gas, and one-twentieth of those that use hydrogen-nitrogen mixed gas.*
*When 50 NL/min is used 24 hours a day, 365 days per year
* Estimated by our company based on gas prices as of February 2020

Initiatives for safety

Equipped with features such as a dual monitoring system that monitors the concentration of both hydrogen-nitrogen mixed gas and the atmospheric concentration within the equipment, an instant-stop function, and a safety exhaust function (patent pending), allowing safe operation of trace gas generation equipment with peace of mind.

Reduced burden on workers

Gas can be generated simply by refilling with purified water, eliminating the need for the frequent gas cylinder replacement that is such a burden on workers. Users perform daily operations using the "Start" and "Stop" buttons, with no other troublesome settings required.
