Helium leak detector He-490S

heliumtracer gasautomated

Product overview
The He-490S is a portable tracer-gas helium leak detector designed for industrial quality control. It offers direct-reading sensitivity to 5 x 10^-8 atm·cc/s, a response time under 0.5 second, helium background suppression (auto-zero) and fast start-up. The instrument can be integrated with the Smart Charge 5 evacuation and backfill station for automated workflows.
