Problems solved by technology

However, the existing pH meters have a common problem, that is, they need to be cleaned every time they are used to ensure the accuracy of measurement.
For occasions that require long-term continuous monitoring of water quality and high maintenance costs, this pH meter is no longer practical

Embodiment Construction

[0011] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0012] figure 1 It is a structural schematic diagram of a pH meter, which includes a pH meter main body 1, an ultrasonic generator 2, a cable 3, an ultrasonic transducer 4, a mesh cover 5 and an electrode bulb 6. The inside of the main body 1 of the pH meter is a 3mol / Lkcl buffer solution containing saturated AgCl, and the pH value is 7. Under normal circumstances, the H ions in the solution to be tested can enter the interior of the pH meter body 1 through the pH meter electrode bulb 6, and the electrodes inside the pH meter body 1 will detect the potential change, thereby obtaining the pH value of the solution to be tested. When the surface of the pH meter electrode bulb 6 is polluted by the solution to be measured, the H ion channel will be blocked, and the pH meter will not be able to detect the potential change, th...

Abstract

The invention relates to a PH meter with an ultrasonic self-cleaning function. The PH meter comprises a PH meter main body 1 and an electrode bulb (6) connected with the PH meter main body 1; the PH meter further comprises an ultrasonic self-cleaning module; the ultrasonic self-cleaning module comprises an ultrasonic generator (2), an ultrasonic energy converter (4) and a metal screen cover (5); the ultrasonic energy converter is located near the electrode bulb (6); and the metal screen cover (5) covers the outer part of the electrode bulb (6) and is used for forming oscillation near the surface of the electrode bulb (6) by ultrasonic waves generated by the ultrasonic energy converter (4). With the adoption of the PH meter, the problem of self-cleaning of the surface of a PH sensor is solved, so that long-period continuous monitoring on ocean water quality with the sensor can be easily realized.

Description

technical field [0001] The invention relates to the field of pH meter devices, in particular to the field of pH meter devices with self-cleaning function. Background technique [0002] The utilization of seawater is an important way to solve the shortage of water resources in my country's coastal areas. Because marine environmental monitoring is affected by many factors such as the harsh marine monitoring environment and the variety of monitoring objects, it is difficult to realize it with ordinary equipment and technology. At present, the three-dimensional monitoring system of the marine environment using wireless sensor networks is a relatively effective method, and it is also one of the current frontier research hotspots. [0003] Generally speaking, the monitoring of sea water quality needs to monitor many indicators, such as dissolved oxygen, salinity, temperature and pH value, among which the pH value is a very important indicator. However, the existing pH meters all ...
