型号：CCW-101空气、水质清净度测试仪（悬浮粉尘观察仪） 

 
    特点：体积小、操作简便，能针对肉眼所难以看见的空气悬浮粉尘，或是水中悬浮物质，任何
人都可以随时、随地做清净度测量的简易测试仪。适用场所：无尘室、医疗院所、精密实验室、餐厅、办公室、生活环境、居家空间、各类工厂环境与各式空气清净设备与水质清静过滤设备的功能测试等。
测试原理：在黑暗的夜空中，我们能轻易的将天上的众多星辰观察的一清二楚，本测试仪就是利用这种原理，将捕捉的空气利用强光照射，去观察悬浮粉尘的状况。也可利用附加的水瓶，去测试水中的悬浮物质浓度。而能观察到的粒子，是指在短时间内不受重力影响而沉降的粉尘（游浮粒子状物质），若以粒径区分，是指数十um至0.3um之间的粉体或微粉体。

Model: CCW-101 air and water clean Tester (suspended dust observation instrument)

  
Features: small size, easy to operate, can be difficult for the naked eye to see the air suspension of dust, or water, suspended material, any
Person may at any time, anywhere to do a simple clean measurement tester. Application areas: clean rooms, medical facilities, sophisticated laboratories, restaurants, offices, living environment, home space, various types of plant equipment, clean environment and a variety of air filtration equipment and water quality quiet functional testing.
Test principle: In the dark night sky, we can easily observe the sky of the many stars of the clear-cut, this tester is to take advantage of this principle, will capture the air using light irradiation, to observe the status of suspended dust. Additional water bottles can also be used to test the concentration of suspended material in water. The particles can be observed, is not subject to the influence of gravity in a short time of settlement of dust (particle-like substance floating tour), if particle size distinction is between the index of 10 um to 0.3um powder or body powder .
