Abstract
The utility model discloses a three-composite flat pH electrode, which comprises an electrode body (1) in which an induction liquid is arranged, and is characterized in that: a plane on the front end of the electrode body (1) is provided with a hole (3) covered with an electrode sensitive film (2), and the front end of the electrode body (1) is also provided with a temperature compensation resistor (4). The three-composite pH electrode combines measurement, reference and temperature, the electrode sensitive film used by the utility model is not in a shape of a glass ball, therefore, the front end of the electrode is flat, wear-resistant and long in service life, and as tested by applicant, the utility model has excellent measurement accuracy and stability, compared with the prior art, the utility model has the advantages of the adaptability to the measurement of lime slurry and long service life.
Description
Technical field
The utility model relates to a kind of three compound flat pH electrodes, belongs to pH electrode technology field.
Background technology
PH electrode on the market all is to adopt the glass sensitive membrane at present, at the electrode body front end glass bead is installed, and temperature compensation resistance is installed in the glass bead, and induced liquid is responded to the pH value of measuring liquid by glass bead.When measuring lime slurry on the power plant desulfurization operation, because the particle and the pressure of lime slurry, pH electrode glass ball weares and teares easily and breaks, and serviceable life is very short.
Summary of the invention
The purpose of this utility model is: provide and measure the lime slurry use on a kind of suitable power plant desulfurization, three compound flat pH electrodes of long service life are to overcome the deficiencies in the prior art.
The utility model is to constitute like this: structure comprises electrode body, is provided with induced liquid in the electrode body, is provided with the hole on the plane of electrode body front end, and coated electrode sensitive membrane on the hole also is provided with temperature compensation resistance at the electrode body front end.
Three compound pH electrodes are meant measurement, reference, temperature groups are lumped together, and the electrode sensitive film that the utility model adopts is not the glass bead shape, so the electrode front end is flat, wear-resisting and long service life.Through applicant's test, measuring accuracy of the present utility model and stability are all fine.Compare with prior art, the utlity model has the suitable lime slurry of measuring and use advantages such as life-span length.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is the vertical view of accompanying drawing 1.
Embodiment
Embodiment of the present utility model: make electrode body 1, in electrode body 1, induced liquid is housed, on the plane of electrode body 1 front end, makes hole 3, coated electrode sensitive membrane 2 on hole 3, electrode sensitive film 2 and electrode body 1 front end are in one plane installed temperature compensation resistance 4 at electrode body 1 front end.
Claims (1)
1. compound flat pH electrode, structure comprises electrode body (1), and electrode body is provided with induced liquid in (1), it is characterized in that: be provided with hole (3) on the plane of electrode body (1) front end, coated electrode sensitive membrane (2) is gone up in hole (3), also is provided with temperature compensation resistance (4) at electrode body (1) front end.
