Description

Product Overview
The Hx-490S Dual Gas is an industrial portable sniffing leak detector for Helium and Hydrogen. It uses an industrial-grade mass spectrometer to provide high sensitivity, fast response and compact footprint. The built-in calibrated dual-purpose leak standard and simple user interface allow quick selection between helium and hydrogen for tracer-gas tests.
