Embodiment
Below in conjunction with accompanying drawing, further set forth the utility model.
As shown in drawings, the utility model comprises combined environment test case 1, data collecting card 4, constant temperature reagent trough 5, temperature sensor 6, humidity sensor 7, liquid level sensor 8 and reagent bottle 19.
Water Test Kits 18 to be tested lies in a horizontal plane in combined environment test case 1, and the degree sensor 6 of installing on Water Test Kits 18 is connected with the input end of data collecting card 4 with humidity sensor 7; In constant temperature reagent trough 5 outside combined environment test case 1, reagent bottle 19 is housed, in each reagent bottle 19, extraction catheter is connected with each stopple coupon on Water Test Kits 18 through combined environment test case 1, in reagent bottle 19, be provided with liquid level sensor 8, each liquid level sensor 8 is all connected with the input end of data collecting card 4.
Output terminal output temperature, humidity and the liquid level signal of data collecting card 4, can be connected with outside computing machine.
Data collecting card 4 can adopt MW100-E-1H data collecting card.
The utility model can be detected Water Test Kits is carried out to accelerated life test by temperature, humidity and liquid level sensor, and process of the test is monitored, and acquisition and recording accelerates stress level, records corresponding fault-time.
Implementation process of the present utility model is as follows:
Measure in real time the temperature and humidity of monitoring Water Test Kits, the judgement of can losing efficacy.Test is as when testting the Water Test Kits of sample, if lost efficacy, by the liquid level sensor in temperature sensor, humidity sensor and reagent bottle, record temperature, humidity and level value, and by data collecting card 4 by collect sample fails time temperature and humidity and liquid level communication go out.
A specific embodiment step of the present utility model is:
1) temperature that constant temperature reagent trough is set is 5 ℃; Test specimen Water Test Kits is placed in combined environment test case 1, and the line that plugs in, is fixed on temperature sensor 6 and humidity sensor 7 on the circuit board in Water Test Kits; The Reagent Tube of test specimen is put into corresponding reagent bottle 19.
