Abstract
The utility model relates to a dissolved oxygen automatic monitoring device, which comprises a cathode, an anode, between the two electrodes, a probe, cables and a casing with filling hole; wherein, the probe comprises electrolyte between the two electrodes and a sealing protective layer outside the electrodes. The utility model is characterized in also comprising a tubular filter guard fixed at the casing, and a slinger is arranged at the upper end of the filer screen; a magnetic stirrer is positioned at the lower end. The utility model has the advantages that: the long-term automatic testing can be implemented, and the measurement is accurate and convenient, thereby the utility model is particularly applicable for breeding plants, reservoirs, lakes and oceans and other occasions.
Description
The utility model relates to a kind of automatic dissolved oxygen DO monitoring device.
Existing dissolved oxygen DO detector can only be done the detection of short time, must manually stir near the aqua region the probe when measuring, otherwise measures inaccurately, and this has also just limited will have the people to operate at the scene, at a distance field monitoring.
The purpose of this utility model provides a kind of automatic dissolved oxygen DO monitoring device, and it can overcome the above-mentioned deficiency of present dissolved oxygen DO detector.
The utility model only is provided with a tubular filter guard, and in this bottom of advancing screen cover a stirrer is set on the prior art basis outside existing detector.
Further specify the utility model below by drawings and Examples.
Accompanying drawing is a structural representation of the present utility model.
As figure; the utility model comprises the shell 9 of the probe, cable 6 and the band liquid injection hole 8 that are made of negative electrode 2, anode 3, therebetween electrolytic solution 4 and its outer seal protection layer 5 and oxygen permeation membrane 11; it is characterized in that it also comprises contains and is fixed in a tubular filter guard 10 on the shell 9; and be provided with suspension ring 7 in this filtering screen upper end, the lower end then is provided with a stirrer 1.Stirrer 1 should be selected a magnetic stirring apparatus for use.
When using the utility model, hitch suspension ring 7, the utility model is placed water to be measured, connect cable 6, promptly start working with nylon rope.
The utility model is particularly suitable for plant, reservoir, lake and ocean, and it is long-term monitoring automatically.
