Get ready for full-time sniffing applications with our new generation Helium and Hydrogen sniffer leak detector.

Do you need easy, fast and repeatable measurements to increase your productivity and enhance your quality level? The ASM 306 S will help you to meet those challenges, whether Helium or Hydrogen is used as tracer gas.

Pfeiffer Vacuum is one of the world’s leading providers of vacuum and leak testing solutions. In order to complete our leak detection product portfolio, we are introducing a breakthrough unit addressing any industrial sniffing applications, especially refrigeration and air conditioning.

Compact unit and ergonomic sniffer probe

Based on over 50 years of know-how in leak detection, you will get all the advantages of a proven technology regarding sensitivity, accuracy and repeatability. Co-designed with the user in mind, the ergonomics of the sniffer probe has been a major focus allowing the operator to be able to hold the sniffer probe during their entire working shift. The high flow probe will help you pinpoint leaks easily without missing any of them. The main display of the ASM 306 S gives all necessary information for testing and the test information is visible directly on the probe for easy visual management, with color LEDs lightning up in real time in accordance to the display.
