MD-490S Portable Dry Helium Leak Detector – Sniffer Model
AVAILABLE UNDER OUR RENTAL PROGRAM
The MD-490S is a leader among portable tracer gas leak detectors. With a response time less than 0.5 seconds, sensitivity to 10-8 direct reading atm-cc/sec, and the ability to zero-out background, this is the most aggressive portable leak detector in the industry. The MD-490S is fully integrateable with our SmartChargeIII Evacuation and Backfill Station.
