How does it work? The sensor ultrasonically recognizes the attenuation and dielectric properties of the liquid or air present. Digital sampling insures precise interpretation. The resulting output signal identifies the condition sensed. (read more)

The Adixen Sensistor H2000 tracer gas leak detector is up to 1000X more sensitive than pressure decay testing and an economic alternative to helium testing. This industrial leak detector can measure pressure drop in order to disclose leaks and localize them with a safe mixture of N₂/H₂ as a trace gas. (read more)

Incorporating advanced technology in the area of mass spectrometry and vacuum technology (patents pending), the PICO® helium sniffer provides fast, contamination-free, helium leak detection. As a sniffing-style helium leak detector, it detects leaks from pressurized lines or components with a minimum detectable leak rate of 1 x 10^-7 atm-cc/s. (read more)

The Qualichek 200 is an ultra high sensitivity trace gas leak detector for accurately locating and quantifying leaks. The Qualichek 200 responds to SF6 and other electron capturing compounds and can display leak rate or concentration. It is equipped with one of the most sensitive gas detection systems ever developed and can detect leak rates as low as 1x1010 ml/sec SF6 or concentration of 0.01ppm (read more)

Model VPE ultrasonic leak detector and bearing checker offers high sensitivity and great sound quality in a compact package. Designed for one hand operation, this lower cost instrument has many of the same quality features as the VPE 1000 offering patented heterodyne technology. (read more)

The Qualichek 196 is portable electronic gas leak detector for locating and measuring leaks quickly, precisely and cleanly. Sensitivity automatically adjusts to leak rate with maximum leak rates recorded and displayed. A detachable probe allows access to even difficult sites with the convenience of single hand operation... (read more)

GD-3300 Combustible Gas Leak Detector with 16" inch Gooseneck detector, easy to measure the hard-reached areas. (read more)

The Adixen EXTRIMA leak detector, by Alcatel Vacuum Products, Inc., is intended for leak detection with diluted hydrogen as trace gas in explosive environments, where the safety requirements are extremely high. The detector is intrinsically safe which means that it under no circumstances can ignite the explosive gas. (read more)
