Revolutionary Protection

The FlexSonic® Acoustic Gas Leak Detector hears gas leaks that others don’t – the instant they occur. It is the first non-contact gas leak detector of its kind that recognizes unique sound “fingerprints,” analyzing 24 discrete ultrasonic bands, while ignoring nuisance ultrasonic sources. A high-fidelity microphone continuously monitors for the distinct ultrasound emitted by pressurized gas leaks across the widest spectrum of frequencies.

This industrial-quality detector provides another layer of protection in the harshest environments, detecting leaks instantly under virtually all conditions. Place where it is needed, with no need to desensitize. For revolutionary protection in real-world environments, the FlexSonic detector is the proven choice.
