FIELD: measurement equipment.
SUBSTANCE: leak finder comprises the first sensor for detection of a gas component (helium) in sucked gas. Since the sensor is sensitive to saturation or contamination, there is a heat conductivity sensor provided. The heat conductivity sensor has lower sensitivity of detection, however, at high concentrations it is not exposed to risk of contamination. Due to both sensors together a large range may be registered from extremely high sensitivity of measurements to high concentrations of gas component, which may be released in case of high leaks.
EFFECT: increased sensitivity of a device.
