Abstract
The utility model relates to a fast measuring box for aqueous dissolved oxygen with small volume and convenient carrying, and the utility model comprises standard colors, medicine MnSO[4] used for fixing and acidifying water sample when measuring dissolved oxygen, concentrated H[2]SO[4] and K1-OH, an oxygen measuring bottle, a burette, a spare ampoule and a spongy mass body. The utility model can be widely used for measuring aqueous dissolved oxygen, particularly fishery production. The utility model has the characteristics of site sampling, field measuring, simple and practical design, accurate and rapid use, etc.
Description
The utility model relates to a kind of pick-up unit, promptly a kind of water body dissolved oxygen DO speed measuring tank.
The content of dissolved oxygen DO is an important technology index in the fish production in the water.Have only the water body dissolved oxygen content of grasping the fishing pool at any time, in time take the oxygenation measure, just can avoid causing the generation of dead fish or general pool phenomenon because of anoxic., at present, the water body oxygen dissolving value can only adopt iodimetric titration or dissolved-oxygen content analyser to measure.Iodimetric titration need be gathered water sample at the scene, takes back the laboratory titration after fixing and calculates, and technology is difficult to grasp, and can not in time provide data.Dissolved-oxygen content analyser not only costs an arm and a leg, complicated operation, and also too busy to get away iodimetric titration is proofreaied and correct therefore also difficult penetration and promotion.So, be badly in need of a kind of being easy to carry in the fish production, simple to operate, data are the oxygen determinator accurately.
The purpose of this utility model will be developed a kind of carrying exactly, execute-in-place, and water body DO determination device fast and accurately.
Above-mentioned purpose is realized by following technical scheme: the new shell of this practicality is a chest, and case is built-in with the fixedly cavernous body of vessel, and has apparatus such as dropper, and different is to be provided with the standard color range in the case, and to be equipped with drug bottle, oxygen-measuring bottle and standby peace bottle.
Said standard color range is by Sheng standard mother liquor in referring to and posts corresponding oxygen dissolving value label and increase progressively the colorimetric device that volumetric flask constituted of arrangement by certain gradient.
The dissolved oxygen DO speed measuring tank that adopts such scheme to make, can carry, open chest during use, water sample adds medicine, can determine the oxygen dissolving value of the water sample of surveying again with standard color range colorimetric, and whole process only needs about two minutes, thereby overcome the drawback of existing determination techniques, but reached execute-in-place, and quick and precisely, simple and easy to do purpose.
Introduce a kind of embodiment below in conjunction with accompanying drawing: accompanying drawing is the vertical view under the water body dissolved oxygen DO speed measuring tank opening, as seen from the figure, present embodiment is by casing (1), dropper (2), cavernous body (3) and (10), standby peace bottle (4), standard color range (5), oxygen-measuring bottle (6) is equipped with MnSO respectively
4Dense H
2SO
4Form with drug bottle (7), (8), (9) of KI-OH.Because casing is small and light, the user can carry, and during use, opens chest, gathers water sample with oxygen-measuring bottle (6), adds MnSO successively with dropper
4, KI-OH, treat that precipitation reduces to when middle part, splash into dense H again
2SO
4Acidifying is also treated after sediment dissolves it to be sucked in the standby peace bottle, again with standard color range colorimetric, promptly obtains the oxygen dissolving value of the water sample of surveying.
The method for making of standard color range is a lot, but reasonable be to adopt pure iodine to mix with Kl, make the standard mother liquor through diluting titration, seal spelling by the different transparent vessels of quantitatively packing into again and get final product.Be used for the fishery water body dissolved oxygen and measure, its oxygen dissolving value is controlled between the 0-15mg/L.
Claims (2)
1, a kind of water body dissolved oxygen DO speed measuring tank, cavernous body (3), (10) and dropper formations such as (2) by casing (1), case internal fixation vessel is characterized in that, are provided with standard color range (5) in the case, and be equipped with drug bottle (7), (8), (9), oxygen-measuring bottle (6) and standby peace bottle (4).
2, water body dissolved oxygen DO speed measuring tank according to claim 1 is characterized in that said standard color range is by interior Sheng standard mother liquor, and posts corresponding oxygen dissolving value label, and increases progressively the colorimetric device that volumetric flask constituted of arrangement by certain gradient.
