The produced hydrogen is introduced into the interior of the collection cup 7 through the tube head and the three-way pipe at different times, and the upper end of the collection cup 7 is sealed by the collection sealing cover 6. The hydrogen squeezes the red ink in the collection cup 7 into the measuring tube 8 by air pressure, allowing the measuring float 9 to float up inside the measuring tube 8.

Since it is difficult to accurately control the pressing length by manually pressing the piston rod 14, and the telescopic threaded head 17 can be fitted on the outer wall of the piston rod 14 through the fitting spring 19, and can be threadedly connected to the piston rod 14 through threads and thread teeth, the piston rod 14 can be slightly pressed down by rotating with the telescopic threaded head 17, thereby accurately controlling the dripping amount of the catalyst and improving the experimental accuracy.
