Specific embodiment
The technical solution of the utility model is described in detail with reference to attached drawing：One kind fills for ecology of fishes prelarva stress experiment
It puts, including small-sized oxygen increasing pump 9, transparent cabinet 1 and the transparent test bottle 5 being respectively arranged inside transparent cabinet and heating rod 2,
Transparent cabinet internal side wall is respectively arranged with thermometer 3 and pH meter 4, and temperature is calculated as the electronic thermometer of electronic display, pH
The electronics pH meter of having electronic display screen is calculated as, facilitates in experiment and quick and precisely reads temperature, the data of pH value, transparent cabinet outer wall
Drainpipe 8 of its inside of connection is provided with, transparent cabinet outer wall is provided with drainpipe hook 7, drainpipe convenient for collecting, small-sized increasing
Oxygen pump is connected by appendix with box house, is arranged at the in vivo gas transmission pipe end of case and is provided with gas stone 6, small-sized oxygen increasing pump
Oxygenation continues water body in babinet by appendix, the shape of transparent test bottle is up-narrow and down-wide truncated cone-shaped, transparent test bottle
Side wall and bottom offer multiple through holes 10, transparent test bottle is that convenient material drawing and cheap plastic bottle can be used, lead to
Hole is by the diminishing cone-shaped hole in aperture of outer wall to the inner wall of transparent test bottle, can be set according to experiment demand in babinet
The transparent test bottle of multiple parallel groups can be formed by putting several.
The operation principle of the utility model：In practical operation exemplified by measuring prelarva to the tolerance of temperature, it is assumed that experiment
