Accompanying drawing explanation
Fig. 1 is circuit structure schematic diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1: the utility model comprises battery E, first resistance R1 is to the 3rd resistance R3, LED, normal concentration transparent vessel 1, test concentrations transparent vessel 2, first photoresistance RL1, second photoresistance RL2, first triode VT1, second triode VT2, the positive pole of milliammeter mA and potentiometer RP, battery E simultaneously with the collector of the second triode VT2, the collector of the second triode VT2, the base stage of the first triode VT1, the first end of the first photoresistance RL1, the first end of the second photoresistance RL2, second end of the first photoresistance RL1 is connected with the first end of the first resistance R1, the negative pole of battery E simultaneously with the base stage of the second triode VT2, the sliding end of potentiometer RP, second end of the second photoresistance RL2 is connected with the negative pole of LED, second end of the first resistance R1 is connected with the positive pole of LED, the emitter of the second triode VT2 is connected with the first end of the 3rd resistance R3 and the first end of milliammeter mA simultaneously, second end of the 3rd resistance R3 is connected with the first end of potentiometer RP, second end of potentiometer RP is connected with the first end of the second resistance R2, second end of the second resistance R2 is connected with second end of milliammeter mA and the emitter of the first triode VT1 simultaneously, normal concentration transparent vessel 1 is placed between LED and the first photoresistance RL1, and test concentrations transparent vessel 2 is placed between LED and the second photoresistance RL2.
The utility model principle adopts the luminous energy by material, thus understands composition or the character of material.First must survey the penetrating light intensity of standard solution, the concentration of solution to be measured so also just be realised that.LED is as light source.First triode VT1 and the second triode VT2 etc. form difference channel.Do not work at LED, the first photoresistance RL1 and the second photoresistance RL2 gauge without light source be when irradiating, regulator potentiometer RP makes milliammeter mA be designated as O, then school zero is terminated.Now connect the power supply of LED, by this light source, the liquid in normal concentration transparent vessel 1 and tested concentration transparent vessel 2 is irradiated, milliammeter mA just can indicate the concentration of test solution.Milliammeter mA is divided into concentration lattice by related standards, so just can reads concentration value easily.
Component parameter of the present utility model is selected as follows:
First photoresistance RL1 and the second photoresistance RL2 model are GL3516, and the first resistance R1 is 100 Ω, the second resistance R2 is 400 Ω, the 3rd resistance R3 is 500 Ω, battery E is 6V, potentiometer RP is 0-27k Ω, the first triode VT1 and the second triode VT2 model is 3DG6C, LED is 3W light emitting diode.
More than show and describe ultimate principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and instructions just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
