1、 When you find a professional manufacturer and don't focus on a product, it must be professional and the quality is relatively guaranteed.

二、用對比的方法來判斷產品之間的完善可靠程度。

2、 Use the method of comparison to judge the perfection and reliability of products.

A.對比噴咀在相同長寬尺寸的規格里其噴咀數量的多少和分布合理判斷（噴咀多，合理性更好）

A. Compare the number and distribution of nozzles in the specifications of the same length and width (more nozzles, better rationality)

B.對比外尺寸在相同長寬設備里面的有效清洗空間大與小（有效清洗空間面積越大越好

B. Compared with the external dimensions, the effective cleaning space in the equipment with the same length and width is large and small (the larger the effective cleaning space, the better)

C.對比看噴咀是否全噴水沖洗還是半水氣或全氣清洗（全水好）。因為只有全水動力的設備才可以把功能發揮到，清洗的質量和數量遠高于氣動，技術和成本水動高于氣動。

C. Compare whether the nozzle is fully watered or half water gas or full gas cleaning (full water is good), because only full hydrodynamic equipment can give full play to the disinfection function, the quality and quantity of cleaning are much higher than pneumatic, and the technology and cost are higher than pneumatic.

D.對比檢測報告（細菌檢測報告、農藥降解報告、瘦肉精降解報告）

D. Comparative test report (bacterial test report, pesticide degradation report, leptin degradation report)

E.對比有功能的產品，要視其的方法：一是要放藥水不，二是不用放藥水，在同樣不放藥水的情況下對比方式：1.臭氧方式 2.臭氧加紫外光 3.活性碳加臭氧加紫外光 4.臭氧氣量是否可以隨時調整的。在臭氧的方式里面再分，部份噴咀出臭氧水和合部噴咀出臭氧水之分，再視其臭氧溶解方法和效果，效果通過廠家提供的檢測報告的數據對比來判斷。

E. The comparison of products with disinfection function depends on the disinfection method: one is to put disinfectant, the other is not to put disinfectant. In the same case, the comparison method is: 1. Ozone method 2. Ozone plus ultraviolet 3. Activated carbon plus ozone plus ultraviolet 4. Whether the amount of ozone can be adjusted at any time. Divide it in the ozone disinfection method, and some nozzles give ozone According to the ozone dissolution method and effect, the disinfection effect can be judged by comparing the data in the test report provided by the manufacturer.

F.操作越簡單越好

F. The simpler the operation, the better

G.對比是否安裝操作簡易，維修保養方便。

G. Compare whether it is easy to install, operate and maintain.

H.對比在使用過程中有否對水的充分有效循環處理再利用功能。

H. Compare whether there is sufficient and effective circulating disinfection and reuse function of water in the process of use.
