Testech Laser Particle Size Analyzer (FTech-4389)

Repeatability: ≤1% (GBRM D50)
The analyzer measures samples with a distribution range of 0.1-1000µm.The results under same analysis conditions yield good repeatability as shown in the following graph.
a)  Repeatability of a serial test of same sample
 
Technology for Reliable Measurement
1. Dual Lenses Optical System (DLOS) 
DLOS is a patented technology of Bettersize. It integrates forward, sideway and backward scattering to double the detection of scattering lights. Compared with single lens system, DLOS improves resolution and measuring accuracy; compared with dual beam system, DLOS provides more reliable results through a consistent wavelength and continuity of a single laser source.
2. Standard Operation Procedure (SOP)
Analysis is just one click away 
SOP of the analyzer provides an intuitive solution for standardized and automatic testing. Click once on the auto test button, the testing procedure   including water intake, bubble removal, background and obscuration measurement, testing, rinsing, saving results and printing the report will run by itself. Just add sample and the automatic analysis procedure is just one click away.
SOP not only provides a simplified procedure but also avoids human operation error; therefore, SOP ensures the repeatability and accuracy of results.

1. Automatic Centering    

 Function
Guarantee the perfect condition of optical system:
By move the laser detector center point to the focus point of lens before each test, automatic centering function guarantees the perfect condition of optical system, therefore, provides accurate and repeatable testing results.
 
 
 
4. Accuracy Calibration:
Maintain accurate datum lifetime
This function makes operational parameters maintained at consistent conditions, producing consistent and reproducible measurement across the board for all old and new instrument alike.
 
5. Automatic Circulation and Dispersion System:
Revealing the true form of every particle through the laser
The circulation and dispersion system ensures a complete sample dispersion hence make sure that each particle would be accounted for through the laser system.
