It can also measure the MV value of the ion electrode potential when equipped with a corresponding ion selective electrode. The pH meter is widely used in environmental protection, sewage treatment, scientific research, pharmaceuticals, fermentation, chemical industry, aquaculture, tap water and other fields. An existing handheld pH meter needs to be installed with a battery for battery life when in use. The battery cover is easy to fall off and be lost during installation, and the handheld pH meter needs to be searched for each time it is used in a handbag, which is inconvenient to use. In addition, the probe of the pH meter is easily damaged by impact and cannot be protected. In order to solve the above problems, an insertion pH meter is needed.

[0003] The existing insertion type pH meter has the problems of being unable to prevent the battery cover from falling off during operation, being inconvenient to take and use, and being unable to protect the pH meter probe. Therefore, an insertion type pH meter is urgently needed. Utility Model Content

The setting of the hook 3 can clamp the pH meter in the pocket of the coat, and it can be directly taken when in use, which increases the convenience of using the device. Then when the handheld pH meter needs to be used When the test probe 5 is used, the protective sleeve 606 is pulled out downward, and then the limiting ring 603 is rotated so that the limiting ring 603 squeezes and fixes the positioning rod 605. At this time, the test liquid to be tested can flow into the test probe 5 through the test groove 607 for testing. When use is completed, the test probe 5 is rinsed with clean water, and the sewage flows out through the outlet groove 608. The limiting ring 603 is rotated again to release the squeezing of the positioning rod 605, and then the protective sleeve 606 is pushed upward so that the protective sleeve 606 seals the test probe 5. At this time, the positioning rod 605 is adsorbed and fixed by the magnetic block 601 to protect the test probe 5, prevent the test probe 5 from being damaged by external force, and increase the safety of the device.
