The Pfeiffer ASI 35 modular tracer gas leak detector provides the highest performance in helium and hydrogen for industrial leak detection systems. The ASI 35 is combines high performance, reliability and repeatability with maximum up time. The ASI 35 provides maximum performance for helium and hydrogen in integral and localizing test methods. A minimum detectable leak rate for helium of 1.5 · 10-8 in sniffing mode and 5 · 10-12 in vacuum mode.
The ASI 35 is flexible due to its modular design. The vacuum module can be installed in any orientation, and the control panel and electronics module are compatible with 1/2 19 inch rack format. The user interface can be optional as the unit can be controlled by PCs or PLCs. The ASI 35 can sustain very high throughput, and ensures the accuracy and reproducibility of the measurement results. The ASI 35 can handle ultra fast cycle time as short as 1 second.
