Introducing a function

The YDC7 multi-parameter gas discharge detector (hereinafter referred to as the detector) is a portable scratch-proof device. It can measure the differential pressure, negative pressure, methane concentration, pipeline temperature, carbon dioxide, atmospheric pressure and flow at each measuring point in the gas reflow pipeline, calculate and display the mixed flow and pure methane flow in the reflow gas in combination with the diaphragm or Pito tube.
