Embodiment:
Therefore the following stated only, for embodying the preferred embodiment of the utility model principle, does not limit protection domain of the present utility model
As Fig. 1, 2 are depicted as the utility model a kind of single probe directly surveys the detector of P in soil H value and humidity, it comprises pointer numerical value reometer 1 and metal electrode probe 2, described metal electrode probe 2 is composite structure, specific in the present embodiment its by alloy zinc portion 21, the stacked formation of alloyed copper portion 23 and alloy aluminum portion 22, between described alloy zinc portion 21 and alloyed copper portion 23 and be provided with insulation course 24 between alloyed copper portion 23 and alloy aluminum portion 22, described alloyed copper portion 23 and pointer numerical value reometer 1 are electrically connected, described alloy zinc portion 21 and alloy aluminum portion 22 are electrically connected with function numerical value switching device shifter 3, described function numerical value switching device shifter 3 is electrically connected with pointer numerical value reometer 1, on described function numerical value switching device shifter 3, be provided with push button 31.
The head of alloy zinc portion 21 is sharp-pointed taper, the circular hollow column that described alloy aluminum portion 22 is strip.
Alloy aluminum portion 22 is plugged on a housing 4 and with housing 4 and is fixed together, and described function numerical value switching device shifter 3 is arranged on the inside of housing 4, and described push button 31 passes housing 4.
Pointer-type numerical value reometer 1 is arranged in housing 4, and described housing 4 is provided with end closure 5.
The utility model is mainly made up of pointer numerical value reometer 1, metal electrode probe 2 and function numerical value switching device shifter 3, supports without external power source and internal battery power supply.
Principle of work: the utility model is that the metal electrode probe 2 of combined type contacts with soil when in use, utilize the redox reaction generation current in chemical reaction to drive, the interelectrode curent change causing thereby the concentration that induces pH is different with humidity value, after this measure of the change amplification compares, and can obtain as calculated pH concentration and the humidity in different soils.Now the corresponding concentration value of instrument triggers cell data actual in the indicated soil of its electric current indicator, that is to say that the utility model is according to current generated signal value size, trigger corresponding reometer pointer, the indicated value of pointer should be the actual value of pH and humidity in soil.Support without external power source and internal battery power supply, and there is the function (numerical value handoff functionality) of while testing soil pH and humidity.
The utility model technical parameter index:
Measurement range: pH:3-8pH; Humidity: 10%-80%;

The utility model is when in use:
(1) first remove tested soil surface soil layer, and clear up that in soil, all can affect the organic impurities of test result, as leaf, root system etc.; If the soil too dry of measuring point or fertile part are too much, cannot survey the potential of hydrogen of soil time, must be set up in spotting by first water-sprinkling, wait detects after half an hour again.
(2) use before detector, must be first with abrasive cloth or cleaning cotton wiping metal electrode probe 2, in case affect measured value.If metal electrode is popped one's head in, there is protection oil on 2 top layers, must first insert soil for several times, after mill absolute oil layer, re-use.
(3) in the time measuring, in vertical metal electrode probe 2 soil that inserts moistening test point, metal electrode probe 2 will insert the degree of depth of soil by its regulation, and about approximately 5 minutes, institute's measured value is right value.Density, humidity and fertile part of soil too much all may affect detected value, therefore must be at different position probing several, to average.
(4) tester pH-value about 5 minutes is stable, now presses lower side push button 31, and humidity manifests immediately.
(5) insert in the process of tested soil at metal probe, as found, the pointer indication position in the index dial of pointer numerical value reometer 1 is unstable, this be because of soil moisture inhomogeneous extremely.So, need many tests several times, definite net result of averaging.
