Problems solved by technology

The sensor is in direct contact with the medium solution, and the glass electrode on the sensor head is easily damaged due to impact during use. In addition, for some liquid media in production, it is easy to scale outside the glass electrode, resulting in inaccurate pH measurement. And this layer of dirt is not easy to clean
For the measurement of the pH value of the liquid in the pool, if a fixed installation is used, a certain amount of manpower and material resources are required, and maintenance is inconvenient

Embodiment Construction

[0012] The present invention will be further described below in conjunction with accompanying drawing.

[0013] like figure 1 As shown, a floating ball 4 is installed at the tail of the sensor 1 of the pH meter. The floating ball 4 is made of acid and alkali-resistant plastic hollow ball. Set the filter screen 2 outside the glass electrode of the sensor 1 head, set the sleeve 3 outside the filter screen 2, the outer peripheral surface of the sleeve 3 is evenly provided with through holes, and the liquid medium to be measured is formed by the through holes on the sleeve 3 surface Enter, then filtered by the filter screen 2, and finally contact with the glass electrode on the head of the sensor 1, the through-hole sleeve 3 is fixed on the head of the sensor 1 by threads, and the sleeve 3 fixes the filter screen 2 to the glass on the head of the sensor 1 Outside the electrode, the sleeve 3 and the filter screen 2 are all selected acid and alkali resistant plastic materials.

Abstract

The invention discloses a protective device used for PH meter sensor, which is characterized in that a ball float is provided at a sensor rear part, a filter screen is provided at the out of the glass electrode of a sensor head, a sleeve is provided at the outside of the filter screen, the filter screen is fixed at the glass electrode of the sensor head by the sleeve, the through holes are uniformly provided at the outer periphery of the sleeve, when the protective device used for PH meter sensor measures the PH value of a liquid medium, the PH meter sensor is placed in the liquid medium, due to the ball float, the head of the PH meter sensor can not be damaged, because the filter screen and the sleeve are arranged on the head of the PH meter sensor, the solid particles in the liquid medium can not connected to the glass electrode, thereby the deposition is not generated, after a segment time of usage, only the filter screen need be replaced. The protective device used for PH meter sensor has the advantages of simple structure, and can effectively protect the head of the PH meter sensor, and the measurement and the maintenance are convenient.

Description

Technical field: [0001] The invention relates to a pH meter, especially a protection device for a pH meter sensor. Background technique: [0002] The existing pH meter consists of a sensor and a converter. The sensor is in direct contact with the medium solution, and the glass electrode on the sensor head is easily damaged due to impact during use. In addition, for some liquid media in production, it is easy to scale outside the glass electrode, resulting in inaccurate pH measurement. And this layer of dirt is extremely difficult to clean. For the measurement of the pH value of the liquid in the pool, if a fixed installation is used, a certain amount of manpower and material resources are required, and maintenance is inconvenient. Invention content: [0003] Aiming at the deficiencies of the prior art, the present invention aims to provide a protective device for the sensor of the pH meter, to ensure that the glass electrode of the sensor head is not easily damaged d...
