Fig. 1 is the ocean of a prior art pH sensor calibration apparatus structural representation.
As shown in Figure 1, the ocean of prior art is the debugging apparatus with heating and cooling function with pH sensor calibration apparatus, comprises columnar tank 1, and the flume wall 2 of tank 1 is made by the PVC plastics.Inboard at flume wall 2 is provided with the insulation interlayer 3 of being filled by asbestos.Refrigerator pipes 4 and well heater 5 are set in the tank 1.Refrigerator pipes 4 is surrounded on the inboard of tank 1, is connected with the refrigeration machine of tank 1 outside.Well heater 5 is arranged at the bottom of tank 1 inboard.Refrigerator pipes 4 is connected with tank 1 controller outside 8 with connecting line 7 by connecting pipe 6 respectively with well heater 5, and well heater 5 and refrigerator pipes 4 heat up to the standard solution in the tank 1 under the control of controller 8 or lower the temperature.
When the debugging of pH sensor was carried out with pH sensor calibration apparatus in ocean shown in Figure 1, with in the standard solution in the pH sensor placement tank 1, standard solution was special phosphate and the borax soln that uses the distilled water preparation in the marine monitoring with the ocean.The standard solution of gradation displacement pH9, pH6, three kinds of different pH values of pH4 in the tank, heating and cooling running by well heater 5 and refrigerator pipes 4 obtains sensor temperature variation characteristic data from high temperature to low temperature in these three kinds of standard water solution respectively, obtain the related coefficient of measurement value sensor and temperature variation, be used for the ocean that produces is debugged with the pH sensor, make it can in the ocean site environment is used, carry out the measurement of seawater pH value automatically.
The ocean of above-mentioned prior art pH sensor calibration apparatus, the debugging apparatus with liftable temperature function that adopts is the bigger columnar tank of volume, when the sensor in to tank in the standard solution of the different pH values of Sheng is tested, need to use the solution for preparing in a large number, also need to change the standard solution of different pH values, standard solution of every replacing all will repeat the heating and cooling process from high temperature to low temperature.Like this, not only the running time of adjustment test long, and waste standard solution.So the ocean of prior art exists with pH sensor calibration apparatus influences the above-mentioned technical matters that it is applied.
Summary of the invention
The ocean existing problem of pH sensor calibration apparatus at above-mentioned prior art, the utility model is released the ocean pH sensor calibration apparatus of new construction, three little tanks that fill different pH value standard solution are set in tank, need not change different solutions one by one during debugging, can finish heating and cooling process simultaneously to three kinds of different pH value standard solution, can obtain three kinds of pH measurement value sensors in the standard solution at same temperature spot.
The related ocean of the utility model comprises four tanks with pH sensor calibration apparatus, and four tanks are a tank and three little tanks, and three little tanks are respectively elongated cylinder-like structure, place tank.Tank is a cylindrical shape, and the top is provided with bracing frame, and bracing frame connects on tank.Three little tanks are made by stainless steel material, are lifted on the bracing frame equably.Put into water in the tank, place the standard solution of pH9, pH6, three kinds of different pH values of pH4 in three little tanks respectively.The flume wall of tank is made by the PVC plastics, in the inboard of flume wall the insulation interlayer of being filled by asbestos is set.Refrigerator pipes and well heater are set in the tank, and refrigerator pipes is surrounded on the tank madial wall, and is connected with the refrigeration machine of tank outside; Well heater is arranged at the bottom of tank inboard.The little tank heat that stainless steel material is made is transmitted fast, is convenient to heating and cooling and regulates.Refrigerator pipes is connected with the tank controller outside with connecting line by connecting pipe respectively with well heater.
When the practical application of pH sensor calibration apparatus was used in the related ocean of the utility model, the pH sensor was placed on respectively in the little tank, and the water temperature in the tank is by refrigerator and well heater control, and the temperature of the standard solution in the little tank also changes thereupon.Same temperature spot can obtain the ocean pH sensor measurement signal in three kinds of standard solution, obtain measurement voltage signal and the temperature variation related coefficient thereof of pH sensor in different temperatures and different pH standard solution, make development and to debug with the pH sensor be can carry out the measurement of seawater pH value automatically during with the Yu Haiyang site environment ocean that produces.
The utility model adopts integrated form in structural design, need not change the standard solution of different pH values one by one, heating and cooling process is once finished, can finish the multiple sensors debugging task at short notice, saved the pH standard solution, shorten the collating time of sensor, improved test job efficient.
