Helium sniffer leak detectors / ASM142 S – ASM102 S  

Accept no compromise when you require high sensitivity, stability, wide measuring range, fast response time, and clean up time. Alcatel offers all of these features with its high performance helium sniffer leak detectors models ASM 102 S and ASM 142 S. The detectors will pinpoint very small leaks easily and accurately, leaks that may have been missed by a less sensitive system and that may have had an important impact on the quality of your products and/or processes. 

The ASM 102 S is a portable dry leak detector with the flexibility for operating the unit in any orientation.
The ASM 142 S is the industrial helium leak detector sniffer unit that will provides ruggedness and performance for a 24h/day usage in very harsh environment  

The ASM 142 S and ASM 102 S deliver: 

- High sensitivity : 1.10-7 mbar.l/s or 0.1 ppm of helium. The high level of resolution provides fast detection and high sensitivity.
- Wide measuring range : From 0.1 ppm to 100 % helium
- Fast response time : Less than 1 s. using a 5 m/16 ft sniffer probe
- Fast clean-up time
- Excellent stability : The helium signal stability is crucial for detecting small leaks.
- 3 mass option, provides detection of helium (He3) and Hydrogen (H2).   

Exciting new features:
• Enhanced helium signal background suppression with floating auto-zero function to ensure that helium signal never falls below zero.
• New enhanced featured state of the art electronics.
• Voice synthesizer for additional operator interface ability.
• Independent access to primary and secondary filament for fast single filament replacement.
• User friendliness: It takes no more than few minutes to become familiar with the detectors many features and operation : auto-calibration, floating Auto-zero function to enhance sensitivity, helium signal direct readout function and fail set-point to remove all operator interpretation of the test result.  

Markets / Applications:
