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、用对比的方法来判断产品之间的完善可靠程度。

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

A.对比喷咀在相同长宽尺寸的规格里其喷咀数量的多少和分布合理判断（喷咀多，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.对比外尺寸在相同长宽设备里面的有效清洗空间大与小（有效清洗空间面积越大越好

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.对比看喷咀是否全喷水冲洗还是半水气或全气清洗（全水好）。因为只有全水动力的设备才可以把功能发挥到，清洗的质量和数量远高于气动，技术和成本水动高于气动。

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.对比检测报告（细菌检测报告、农药降解报告、瘦肉精降解报告）

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

E.对比有功能的产品，要视其的方法：一是要放药水不，二是不用放药水，在同样不放药水的情况下对比方式：1.臭氧方式 2.臭氧加紫外光 3.活性碳加臭氧加紫外光 4.臭氧气量是否可以随时调整的。在臭氧的方式里面再分，部份喷咀出臭氧水和合部喷咀出臭氧水之分，再视其臭氧溶解方法和效果，效果通过厂家提供的检测报告的数据对比来判断。

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.操作越简单越好

F. The simpler the operation, the better

G.对比是否安装操作简易，维修保养方便。

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

H.对比在使用过程中有否对水的充分有效循环处理再利用功能。

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