Sensistor Technologies has introduced the H2000™, which uses hydrogen as a tracer gas to detect leaks. H2000 is a compact and robust system that is extremely sensitive to hydrogen gas and can be used to detect leaks that are smaller than a bacterium. Using a safe, non-hazardous, 5% hydrogen in 95% nitrogen mixture, it offers flexible detection solutions for a variety of applications, including the ability to disclose and localize leaks, as well as the detection of leaks with high sensitivity, independent of temperature.
