It is wide to use.
Detailed description of the invention
The experiment of Fig. 1 the utility model overall structure figure of constant temperature heating device.
The main view of the experiment of Fig. 2 the utility model constant temperature heating device China and foreign countries circulating pump.
The top view of the experiment of Fig. 3 the utility model constant temperature heating device China and foreign countries circulating pump.
The side view of the experiment of Fig. 4 the utility model constant temperature heating device China and foreign countries circulating pump.
Specific embodiment
The utility model is described in further details with reference to the accompanying drawings and examples.
A kind of experiment constant temperature heating device as shown in Figs 1-4, comprising: heated base 10, water-bath 20, outer circulation pump
30 and hygrosensor 40, the water-bath 20 be fixed on the upper surface of heated base 10, heated base 10 is in water-bath 20
Water heated, the water of 20 lower part of water-bath is extracted out, is recirculated back to water-bath 20 by 30 connection water-baths 20 of outer circulation pump
Top, hygrosensor 40 are put under the liquid level of water-bath 20, for detecting the temperature of water-bath, the connection heating of hygrosensor 40
Temperature is simultaneously back to heated base 10 by pedestal 10, and the water temperature that heated base 10 controls in water-bath 20 is constant；When detecting water
Bath temperature is higher than set temperature, stops heating；When detecting that bath temperature lower than set temperature, restarts to heat, so follow
Ring heating guarantees that the water temperature in water-bath 20 is equal to set temperature.
Heated base 10 includes: switch 11, adjusting knob 12, digital display screen 13 and indicator light 14, and switch 11 is fixed on
