MD-490S HELIUM LEAK TESTER

PORTABLE DRY HELIUM LEAK DETECTOR SNIFFER MODEL

The MD-490S is a leader among portable tracer gas leak detectors. With a response time of less than 0.5 seconds, sensitivity to 10-8 direct reading atm-cc/sec, and the ability to zero out the background, this is the industry’s most aggressive portable leak detector.

The MD-490S is fully integrable with our Smart Charge 5.

It also meets the stringent requirements for robustness, reliability and ease of maintenance that are essential in any industrial environment..
