Example Embodiment
[0066] Example 1:
[0067] According to the concept of the technical scheme of the above-mentioned specific embodiments, embodiment 1 of the present invention proposes an ultrapure water PH detection device, including an automatic raw water inlet device, an automatic drainage device, an automatic KCl dosing device, a KCl dissolving device, and a PH detection instrument.
[0068] Add KCl to the test water sample to increase the potential difference between the two poles of the PH detector to make it reach the normal measurement range of the PH detector; set up a sample detection pool, set up a matching automatic water intake, drainage, and dosing system to realize the equipment Automatic sampling detection function; for the system components, a compact layout is adopted, and a plastic shell is set to improve the appearance of the equipment; the KCl dissolution tank is placed on the top of the equipment shell, and the KCl dissolution tank is higher than the water inlet of the detectio...
Example Embodiment
[0084] Example 2:
[0085] According to the ultrapure water PH detection equipment shown in Figure 1 (a), Figure 1 (b) and Figure 1 (c), the inlet solenoid valve 1, the drain solenoid valve 2, the KCl dosing solenoid valve 3, and the PH detection Instrument 4, KCl dissolving tank 5, sample detection pool 6, inlet pipe reserved port 7, KCl dissolving tank drug outlet 8, drain pipe reserved port 9, solenoid valve wiring reserved port 10, detection pool water inlet 11, detection The water outlet 12 of the pool, the water inlet 13 of the detection pool, and the housing 14 of the equipment.
[0086] Such as figure 2 As shown, the overall working principle of the invention is as follows:
[0087] When detecting the pH of ultrapure water, add KCl solution to the water sample to increase the ion content of the water sample, thereby increasing the potential difference between the two poles of the PH detection instrument, making it possible to detect the pH of ultrapure water;
[0088] a. The...
