Technical Field

[0002] A pH meter is an instrument used to measure the pH value of a solution. It is used in many reaction tanks to measure the pH value of a solution. When measuring the pH value of a solution in a tank, the pH meter probe needs to be inserted into the container and the solution needs to immerse the probe. Direct contact between the pH meter probe and the solution can easily contaminate the entire solution, making it difficult to use other solutions in practice, thus causing waste. However, pouring out part of the sample for testing makes it difficult to ensure that the sample immerses the pH meter probe.

[0003] Therefore, it is necessary to provide a new pH sampling and measuring device to solve the above technical problems. Utility Model Content

[0013] The utility model provides a pH sampling and measuring device:

[0014] 1. Water samples can be collected through the sampling tube, while ensuring that a small amount of water samples can immerse the detection probe body. The slider connects the sampling tube and the support plate, which has little effect on the up and down adjustment of the sampling tube. The distance between the sampling tube and the inner wall of the container containing the liquid can be adjusted by adjusting the position of the card plate on the support plate to reduce the probability of collision damage. The height of the piston plate can be adjusted by adjusting the extension length of the output rod of the electric telescopic rod, thereby adjusting the air pressure in the cylinder body, and then adjusting the air pressure in the sampling tube to achieve the water pumping effect. The gas in the sampling tube can enter the cylinder body through the exhaust pipe. The branch pipe cooperates with two one-way valves to prevent the gas from flowing back during the air extraction and ventilation, causing the liquid to flow out again;

[0015] 2. The rubber ring can increase the sealing performance between the piston plate and the cylinder to prevent air leakage, thereby ensuring the air extraction effect. The air hole can prevent the high air pressure on the top of the piston plate from affecting the normal movement of the piston plate, and is used to maintain air pressure balance. The silicone mesh can protect the sampling tube to prevent it from easily breaking. The transparent glass sampling tube is more convenient for staff to observe the amount of water sample extraction. The hose section can ensure the normal up and down movement of the sampling tube. The height of the sampling tube can be stabilized by holding the handle. The card plate on the edge of the container can be stabilized by pressing the stabilizing frame. The soft pad can increase the comfort of the staff's hand when pressing the stabilizing frame.

[0033] When in use, first pour the liquid into the sample container, clean the sampling tube 4, and clamp the card plate 1 at the opening of the container containing the liquid to be tested. At this time, the sampling tube 4 is in contact with the liquid surface.
