Embodiment Construction

[0017] Such as Figure 1~2 As shown, the present invention consists of a cable 11, a waterproof rubber gasket 12, an electrode lead 13, an electrode screw cap 14, an electrode insulating tube 15, an electrode tube fixing bolt 16, a sensor housing 17, an insulating seal 18, a sensor electrode 19, and a reference electrode 10. Composition, the sensor electrode 19 and the reference electrode 10 are electrically connected to the potentiometer 4 respectively. The sensor electrode 19 and the reference electrode 10 are covered with an electrode insulation tube 15 outside. One ends of the two electrodes respectively extend out of the cylindrical electrode insulation tube 15 and are in contact with the solution 2 to be tested. The other ends of the two electrodes respectively pass through the electrode lead 13 Connected to the cable 11, the electrode insulating tube 15 is inserted through the sensor housing 17, and an insulating seal 18 is formed between the sensor housing 17. One end of th...

Abstract

A sensor for measuring the content of sulfate reducing bacteria has a sensing electrode and a reference electrode, which are respectively connected to potentiometer. Said electrodes are wrapped by electrically insulative tubes. Their one ends are extended out of said electrically insulative tubes and their another ends are connected to cables. The casing of said sensor is insulatively sealed. Its advantage is high speed.

Description

Technical field [0001] The invention relates to a measuring sensor, in particular to a sensor capable of quickly measuring the content of sulfate reducing bacteria in seawater. Background technique [0002] Sulfate-reducing bacteria widely exist in the seabed area and soil. It is a microorganism that can accelerate the corrosion and destruction of metals and concrete. In the research and control of corrosion damage caused by sulfate-reducing bacteria, it is often necessary to measure seawater, sewage or soil. The content of sulfate-reducing bacteria. At present, the commonly used detection method for sulfate-reducing bacteria is the maximum possible counting method (MPN), that is, using multi-tube fermentation technology, cultured in an incubator at 29±1℃ for 21 days, according to the black precipitate and hydrogen sulfide produced in the test tube For odor, use the blackness comparison method to count the number of sulfate-reducing bacteria in the sample. The disadvantage is tha...
