The invention relates to a multifunctional gas quantitative
leak detector which comprises a
leak detector body, a probe and an
electric control unit. An inlet filter seat is arranged on the top of the
leak detector body, a power chamber is arranged inside the lower end of the leak
detector body, and a flow chamber is positioned on the upper portion of the power chamber; a silencing plate is arranged at the bottom of the inlet filter seat, a
check valve is arranged in the center of the top of the inlet filter seat, and a
gas pipeline is connected with the inlet filter seat by the
check valve; a
pressure sensor is further arranged between the top of the inlet filter seat and the
check valve; the probe comprises a probe shell and a fan; the probe shell is fixedly connected to the
tail end of the
gas pipeline; the fan is arranged in a
gas chamber of the probe shell; the
electric control unit is arranged inside the leak
detector body and comprises a controller module, a power switch module, a button module, a gas sensing module, a detection module, a gas alarm module, an indicator lamp module and a
power management module. The multifunctional gas quantitative leak
detector has the advantages that the multifunctional gas quantitative leak detector is easy and convenient to operate and high in
leak detection accuracy and detection efficiency and is small, the flow of to-be-detected gas can be voluntarily adjusted, and the gas can be quantitatively detected.
