Concrete, above-mentioned functions district also includes initiating key and/or Pause key and/or close key.
This utility model has following useful technique effect: this practicality can preset the quality of the liquid of needs,
Automatic dripping sets the liquid of quality, convenient, accurately；The gravity sensor of this practicality measures and is positioned over the object on the first base
Quality, the first drain straight tube is to take liquid in unsettled immersion liquid, does not interferes with check weighing, and measurement result is accurate；The electricity of this practicality
Magnet valve knob can adjust the valve block opening degree of electromagnetic valve, regulates dripping of liquid with this fast, it is adaptable to multiple occasion；This reality
Drive liquid to flow with by the power of peristaltic pump, do not reflux, access and pick out conveniently, it is also possible at certain model
Enclose interior regulation flow；The functional areas of this practicality are provided with several functions, it is possible to increase the automaticity of liquid dropping, reduce people
For impact.
