Particle Size Analyzer Price and Cost

-When it comes to particle size analyzer price we have to specify all types of world's most widely used particle size analyzer. As we know different theories or principles being used by different manufacturers generate different particle size analyer cost.  
-There are the following particle size analyzers: light scattering particle size analyzer (most we call it laser diffraction particle size analyzer since laser is the best light being frequently used),sedimentation particle size analyzer,dynamic light scattering (DLS/PCS) particle size analyzer,ultrasonic particle size analyzer,microscopy particle size analyzer,online particle size analyzer, etc. 
-The most polular today is laser particle size analyzer, the price is subject to the size range or the test method (liquid or dry). Liquid-test laser particle size analyzers with broad size range are much more expensive than those with narrow size range. Dry-test laser particle size analyzers are relatively more expensive than same size-range liquid-test laser particle size analyzers. In addition to dry dispersion technology there are more auxiliary accessories are required such as vacuum and air compressor. The cost of submicron(less than 1 micrometer) laser particle size analyzer is higher than micron(from 1 micrometer to 1000 micrometer)laser particle size analyzer. The portable particle size analyzer price maybe higher than a desk top particle size analyzer. The laser particle size analyzer made by an advanced country is much higher than a laser particle size analyzer made by a developing country.  
-Before going on to purchase, user has to specify the following situations: 
a. User's own budget decides the choice of an instruments made by China or made by advanced countries: usually imported particle size analyzer cost around USD 60,000/set however china-made cost around USD 10,000/set to USD 30,000/set (To be contrinue)  
b. Decide purchasing dry method or liquid method particle size analyzers according to properties of samples to be measured: If we could find proper agent, whatever water or other liquids, which does not act with samples to be tested, liquid particle size analyzers are recommended in order to save the cost. Liquid particle size analyzers give stable results and cost-effective price. However if the sample is special and easily acts with liquids, dry laser particle size analyzers are recommended, but the price is much higher. 
c. Select instrument model suitable for user’s sample size range according to the primary particle size distribution: Bigger size range cost bigger budget.Usually, the most cost-effective choice is to enquire the particle size analyzers with size range a bit broader than user’s requirement.The particle size analyzers in the nowaday market covers 2-3 ranges, but most samples to be tested in regular industrial applications come within only one range. If a buyer's particle size distribution is narrow, but he order a particle size analyzer with extended size range, it looks like he measure a cell with a meter, such move will reduce the test accuracy and the price and performance ratio becomes much lower other than higher. The sectional size range could lead to poor accuracy which lead to poor price as well. However a full course such as 0.02 to 2000 micrometer is costly.
d. Select the particle size analyzer type according to the purpose: High-end and most-advanced particle size analyzer is not necessary if only a regular inspection is required. Basic particle size analyzers have gone through years of improvement and features optimized structure,stable test particle size analysis results as well as lower rate. Those particle size analyzers manufacturers with large requirement of test, automaticly and intelligently advanced particle size analyzers are recommended since it can enormously reduce the work burden for the operator. High-end particle size analyzers are designed for colleagues and scientific institutes who focus on the research. Such particle size analyzers are highly rated with extended size range, high precision and complicated configuration.
