Embodiment
Embodiment 1
The device of present embodiment is referring to Fig. 1, and wherein the shape of each parts, structure and annexation each other are respectively as Fig. 2-shown in Figure 5.
See also Fig. 2-Fig. 5, feeler lever 1 is made up of the body of rod 5, handle 6, probe sheath 7, connector 8.The body of rod 5 is the metal tube of a hollow, and its both sides, upper end respectively screw togather one handle 6, are used for gripping and operating this device.For preventing heat conduction and acid and alkali corrosion, the machine that the is externally coated with macromolecular material protective seam 18 of the body of rod 5, the protective seam that present embodiment applies is a teflon, and indicates scale 19, inserts the degree of depth of test substance with control probe easily.Plug a gas circuit pipe 9 in the body of rod 5, this gas circuit pipe 9 can be made of teflon or metal material, and present embodiment adopts polytetrafluoroethylmaterial material to make, its internal diameter is 0.5-1.5mm, this example adopts 1mm, and external diameter gets final product less than the internal diameter of the body of rod 5, to be inserted in easily in the body of rod 5.Gas circuit pipe 9 lower ends plug with the upper end taper joint 12 of connector 8 and link to each other, and after the binding, connector 8 upper end screw threads 16 are screwed togather with the body of rod 5 bottoms, and connector 8 lower end screw threads 17 screw togather with probe sheath 7.The long probe 13 of 2cm is stretched out in the connector bottom, and sieve shape pore 15 above gathers.Probe sheath 7 is the hollow-cone body, long 13cm, tapering 3cm wherein, tubular portion 10cm, there is the body of 5cm length to be scraped out window in the middle of the tubular portion, coated outside one deck 100 order stainless (steel) wires 27 make in the object under test gas can freely enter probe sheath 7 and sieve shape pore 15 and enter connector gas circuit 14 smoothly, thereby enter gas circuit 9.
The can 23 at the top of feeler lever 1 is fixing by screw rod 10 with the body of rod 5 upper end shaft collars 24, sampler chamber 2 is fixing by screw rod 11 with can 23, aspiration pump 3 is fixing by screw rod 25 with can, gas circuit 9 upper ends are linked to each other with the inlet end 20 of aspiration pump 3, and the outlet side 21 of aspiration pump 3 links to each other with the inlet end 22 of sampler chamber 2.Sampler chamber output line 26 links to each other with computer data amount IO card 28.
