最近很多客户打来电话购买激光粒度仪,但是不知道需要考虑什么指标?济南微纳小编今天就为大家介绍一下。

Recently a lot of customer calls to buy laser granulometer, but don't know what indicators need to be considered? Jinan micro-nano small make up today is to introduce for everybody.
 

如果你打算买一台激光粒度仪的话你要参考以下五点:

If you are going to buy a laser particle size instrument you want to refer to the following five:

第一、测量范围:分为纳米级和微米级

First, the measuring range: can be divided into nanometer level and micro level

第二、测试方法:干法和湿法

Second, test methods: dry method and wet method

第三、测试原理:米氏散射和动态光散射

Third, test principle: mie scattering and dynamic light scattering

第四、激光器:一般分为半导体激光器和HE-NE气体激光器,半导体激光器优点使用前无需预热,使用寿命长,缺点是发光不稳定,光斑可能不圆,气体激光器使用前应先预热,夏季在15分钟冬季在30分钟左右,优点是光斑圆,发光稳定。

Fourth, the laser: generally divided into semiconductor laser and HE - NE gas laser, semiconductor laser advantage without preheating before use, service life is long, the disadvantage is that light is not stable, light may not round, gas laser should be preheated before use, summer in winter in about 30 minutes, 15 minutes advantage is light round, light stability.

第五、探测器的数量,也叫测量通道,不同的激光粒度仪探测器的环数也不一样,测量的精度也不一样,建议用环数多,排列角度大的
Fifth, the number of detector, also called measurement channels, different particle size the ring number of detectors is different also, the precision of the measurement is different also, suggest use the ring number, large arrangement Angle
