The probe of another termination the 3rd of resistance, the other end ground connection of the second electric capacity.
Further, display unit is liquid crystal display.
Further, input block is button.
The utility model is relative to traditional TDS detection means, it is only necessary to do the adjustment of parameter, Ke Yijian on this basis
The solution of different quality is surveyed, and in the application of different structure device.Not only accuracy of detection is improved the utility model, and application
It is in extensive range.
Brief description of the drawings
Fig. 1 is the schematic diagram of new water quality detecting device；
Fig. 2 is the oscillogram of new water quality detecting device.
Embodiment
To further illustrate each embodiment, the utility model is provided with accompanying drawing.These accompanying drawings are in the utility model is disclosed
A part for appearance, it is mainly to illustrate embodiment, and running of the associated description of specification to explain embodiment can be coordinated former
Reason.Coordinate and refer to these contents, those of ordinary skill in the art will be understood that other possible embodiments and this practicality are new
The advantage of type.Component in figure is not necessarily to scale, and similar element numbers are conventionally used to indicate similar component.
The utility model is further illustrated in conjunction with the drawings and specific embodiments.
As shown in fig.1, the new water quality detecting device of the utility model preferably embodiment, it includes processor list
Member, temperature measuring unit, TDS detection units, display unit and input block, temperature measuring unit, detection unit, display unit and input are single
Member is electrically connected with processor unit respectively, and TDS detection units include the first TDS detection probes, the 2nd TDS detection probes and school
Quasi- circuit, two TDS detection probes and calibration circuit are electrically connected with processor unit respectively.First TDS detection probes, second
TDS detection probes connect the TDS_IO_1 pins and TDS_AD pins of processor unit respectively.
The calibration circuit of the embodiment includes slide rheostat VR, the first electric capacity C1 and first resistor R1, slide rheostat
VR first end is connected with control end is followed by the 2nd TDS detection probes, and slide rheostat VR the second end connects through first resistor R1
