Description

Multiparameter aquaculture water quality detection combined probe

The utility model belongs to by means of the chemistry of measuring material or physical property is tested or the technical field of analysis of material, particularly belong to a kind of testing tool of testing or analyze with electrochemical method, relate to a kind of multiparameter aquaculture water quality detection combined probe (GO1N27/27).

At present, both at home and abroad the main mensuration project of the aquaculture water quality testing meter of producing only is dissolved oxygen DO, temperature usually, or dissolved oxygen DO, pH, temperature, or dissolved oxygen DO, pH, electricity is led and temperature.In recent years, have in the detector of this type of minority and set up ammonia or solubility sulphur (S ^2-) the mensuration project, but all belong to the sampling and measuring project.In above-mentioned main mensuration project, the overwhelming majority still adopts the sampling determination mode.Though have the minority instrument to use immersion lance, measurement parameter is less, generally only be dissolved oxygen DO, temperature, or dissolved oxygen DO, pH and temperature etc., and its basic structure is fixed, can not dismantle or change easily worn part and probe.

Because most instruments all adopt the sampling and measuring mode, less because of the sample volume of sampling and measuring, its sample contacts the back owing to O in the air with air ₂Dissolving, the oxygen level that records is different with actual waters, again owing to absorb CO ₂Make the pH value of measuring also different, other index such as actual NH with actual waters ₃Content also is among the change.

The purpose of this utility model is to provide a kind of multiparameter aquaculture water quality detection combined probe, it directly is immersed in the mensuration waters, can obtain " in real time " and " original position " measurement data, can monitor at any time and influence the chemical property that aquatic products are produced in the aquaculture waters, so that in time take rational regulation measure according to measurement result, aquaculture there is important and practical meanings, also set up in the utility model simultaneously and measured the probe of culturing reducing substances total amount in the waters, enlarged the water quality detection project, can be to profound or close pond, the pool, the water quality of lakebed mud is monitored at any time, also can realize monitoring mensuration to the aquatic products such as fish of bottom growth.

The utility model is realized by following manner: a kind of multiparameter aquaculture water quality detection combined probe; by pedestal; the housing block; the protection housing; balance base and chemical sensor are formed; be fixed with the chemical sensor interface on the pedestal; its key be pedestal with the protection housing between by being threaded; have the bar shaped notch vertically around the protection housing; so that the water in the breed waters can freely enter in the protection housing; fully contact with each chemical sensor; and detect measured signal; can prevent again simultaneously that each chemical sensor and other hard thing from bumping against; to play the effect of each chemical sensor of protection; the lead wire outlet of composite shielding cable on the housing block that connects each chemical sensor interface is protruding; fill out envelope with waterproof gasket cement between the lead wire outlet on composite shielding cable and the housing block; between housing block and pedestal, be provided with the caulking gum packing ring, and fix with screw.

Above-mentioned chemical sensor can comprise oxygen electrode, pH electrode, conductance measurement sensor and sensor for measuring temperature, can also comprise contrast electrode, NH simultaneously ₃Electrode and mensuration are cultured the probe (that is: reducing substances electrode) of reducing substances total amount in the waters.

The ventilated membrane position of above-mentioned oxygen electrode preferably disposes a protective cover; to play the effect of protection oxygen electrode ventilated membrane; and a fluid infusion mouth is preferably offered in the side of contrast electrode, and with the convenient interior solution that replenishes contrast electrode, described reducing substances electrode can be carbon-based electrode.

Can join with screw socket between above-mentioned balance base and the protection housing, the most handy stainless steel material of balance base is made.

Below in conjunction with accompanying drawing shown in the embodiment the utility model is described in further detail.
