[0002] Online ORP combination electrodes are widely used in industries such as tap water, river water, chemicals, and pharmaceuticals. Many of these applications involve high temperature and high pressure environments. Conventional ORP combination electrodes are susceptible to shell rupture in these environments. Even if these conditions don't lead to complete damage, high temperature and high pressure can still affect stability, causing reference potential drift and resulting in errors in the final test results.

The ceramic sand core is sintered and connected to the glass shell, the gold ring is sintered and connected to the bottom end of the glass shell, the potassium chloride ring and the reference glass tube are arranged in the glass shell, the solid gel is arranged between the glass shell, the potassium chloride ring, and the reference glass tube, and the plug is arranged at the top of the glass shell and connected to the lead of the gold ring.
[0006] Furthermore, the solid gel is a polyacrylamide gel.
[0007] Beneficial effects of the utility model:
[0008] Compared with traditional technologies, the present invention adopts solid gel as the filling liquid for high temperature and high pressure environments.

[0012] The present invention will be further described below in conjunction with specific embodiments. It should be understood that the following embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.
[0013] Example 1
[0014] Figure 1 It is a structural diagram of the present utility model.
[0015] like Figure 1 As shown, an ORP electrode for use in high-temperature and high-pressure environments includes: a ceramic sand core 100, a glass shell 200, a gold ring 300, a solid gel 400, a potassium chloride ring 500, a reference glass tube 600, and a plug 700. The ceramic sand core 100 is sintered and connected to the glass shell 200, the gold ring 300 is sintered and connected to the bottom end of the glass shell 200, the potassium chloride ring 500 and the reference glass tube 600 are arranged in the glass shell 200, the solid gel 400 is arranged between the glass shell 200, the potassium chloride ring 500, and the reference glass tube 600, and the plug 700 is arranged at the top of the glass shell 200 and connected to the lead of the gold ring 300.
[0016] Solid Gel 400 is a polyacrylamide gel.
[0017] The innovation of the present invention lies in the use of gold as the electrode measurement material, rather than the commonly used platinum, because gold is more suitable for measuring highly oxidized samples. Furthermore, the ring-shaped structure of gold effectively increases its contact area, making it most advantageous both in sintering with glass and in measuring actual samples. Conventional products slowly consume potassium chloride in the electrode cavity during use, especially under high temperature and high pressure, where this consumption is more pronounced. To extend the life of the electrode, a certain amount of potassium chloride rings 500 are prefabricated in the cavity. The ring-shaped potassium chloride is well placed within the solid gel, thus avoiding the problem of clogging the sand core salt bridge caused by using powdered potassium chloride. The main function of the solid gel is to ensure that the reference system maintains a stable potential under high temperature and high pressure environments. Its morphology remains unchanged by high temperature and high pressure, and the reference potential it provides remains stable under high temperature and high pressure (the potential remains consistent before and after high temperature and high pressure). Currently, conventional electrodes typically use potassium chloride solutions or potassium chloride gels (similar to yogurt), neither of which are solid. Under high temperature and high pressure, the reference potential provided is unstable, and the concentration is also affected by the high temperature, thus affecting the reference potential. Therefore, the solid gel type selected by the present invention is a polyacrylamide gel.
[0018] Compared with traditional technologies, the present invention adopts solid gel as the filling liquid for high temperature and high pressure environments. It will not swell or shrink, can provide a stable reference potential, improve the stability and durability of the electrode, and improve the overall heat resistance and high pressure resistance of the product. It can also effectively isolate the direct contact between the electrode and the sample, reducing the wear and corrosion of the electrode material.
[0019] The above describes the specific implementation of the present invention, but the present invention is not limited thereto. As long as it does not deviate from the purpose of the present invention, the present invention can also have various changes.
