R=| 7.52-5.03|ms/cm=2.49ms/cm.Again such as, when temperature T is 24.0 ℃, in the data processing unit 30 storage standard conductivity value K
SBe 5.01-5.03ms/cm, when being doped with tap water 0.50% in the cow's milk, the actual 4.85ms/cm that is measured as of conductivity K, then deviation value K
R=| K-K
S|, at this moment, because conductivity K measured value is less than K
SThe minimum value of interval value is got standard conductivity value K
S=5.01ms/cm, deviation value K at this moment
RBe K
R=| 4.85-5.03|ms/cm=0.18ms/cm.Under above-mentioned two kinds of sample situations, because deviation value K
RAll greater than the predefined reference value K that departs from
P=0.05ms/cm then can assert qualitatively, and the milk in above-mentioned two kinds of examples also has impurity.Same, the standard conductivity value K of storage in data processing unit 30

RGreater than departing from reference value K
PThe time, the data processing module 33 of data processing unit 30 sends one first signal by second data transmission unit 32 to display unit 40; As described deviation value K
RLess than the above-mentioned reference value K that departs from
PThe time, this data processing unit 30 sends a secondary signal to described display unit 30.
When described display unit 30 was a CRT monitor or light-emitting diode display, this first signal was shown as literal " positive " on described display unit 40, and described secondary signal is shown as literal " feminine gender " on described display unit 40.Certainly, when described display unit 30 was a warning lamp, described first signal can be that lamp is bright, and described secondary signal can be that lamp goes out; When described display unit 30 was two warning lamps, described first signal can be that red light is bright, and described secondary signal can be that green light is bright.Same, when described display unit 30 was one or more loudspeaker, first, second signal can be the combination of different voice signal accordingly, does not describe in detail one by one at this.
When display unit 40 is a display screen, can show various relevant detection information on the described display screen, except that above first, second signal, the conductivity value K that can also show current temperature value T and record, the standard conductivity value K under the associated temperature
SAnd the deviation value K that obtains relatively
R, depart from reference value K in addition
P, and the parameters such as type of milk.
In addition, described display unit 40 can also show that one of described data processing unit 30 is departed from reference value setting module 35 and an information state of selecting module 36.Specifically, not only store standard conductivity value (point value or the interval value) K of milk under different temperatures T in the storage unit 34 of described data processing unit 30
SAnd the predefined reference value K that departs from
P, but also store the standard conductivity value Ks of various breasts under different temperatures T such as sheep breast and reconstituted milk
SAnd the predefined reference value K that departs from accordingly
P
Since the difference in the various milk batch or the place of production, its standard conductivity value K
SCan be different, therefore, can in database, store by type in advance it, in the time need carrying out batch detection to the breast of this type, can select the type of corresponding milk by the selection module 36 of data processing unit 30, and switch function relevant in the described data processing unit 30 with the type of described breast, for example, when needs carry out batch detection to goat milk, can select type by the clauses and subclauses that show on the display unit 30 is " goat milk ", data processing unit 30 is accepted after the above-mentioned selection, to switch data wherein, in the data handling procedure after this, compare only calling the data relevant, and provide corresponding result with goat milk.
In addition because to the difference of the requirement of various milk quality, need sometimes to set flexibly a certain batch, the milk of a certain type depart from reference value K
PCan be provided with this moment by the reference value setting module 35 that departs from of data processing unit 30, promptly, under the quality requirements situation of above-mentioned example, can be by " departing from reference value sets " option that shows on the display unit 30, what preestablish milk departs from reference value K
P=0.05ms/cm, perhaps, that can set milk in advance departs from reference value K
P=0.10ms/cm promptly, means that the required quality of milk of this batch is lower than aforementioned K
PThe situation of=0.05ms/cm.
