Portable gas detectors - Import export

The He-490S is the 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, with advanced features designed specifically for industrial applications. The He-490S can be integrated with our Smart Charge 5 evacuation and backfill station. Fastest response time in the industry (less than 0.5 seconds) Helium background suppression Maintenance free, dry pump Sensitivity to 5 x 10-8 atm cc/sec Less than 3 minutes total start-up time Fully automatic calibration sequence with built-in 10-5 atm cc/sec gas leak Front panel key lock-out Sealed membrane keypad Fully interactive system diagnostics with multilingual displays High output (110dB) adjustable audio alarm Sensitivity: Smallest detectable helium leak rate 5 x 10-8 atm cc/sec Measuring Scale: 7 decades

Gast diaphragm units require no lubrication making these units the perfect choice of installation for critical applications found in medical facilities, laboratory equipment, air sampling devices, portable gas detectors and dental equipment. With their outstanding performance, durability and flexibility, the varied range of Gast oil-less diaphragm air compressors and vacuum pumps are ideal for industrial applications too.
