MainFeatures:
1)Advancedtestprinciple
Dynamicscatteringlighttechnology,Itcouldkeepnanometerparticleoriginalstate,guarantee
realnessandeffectivenessoftestresult.
2)HighsensitivityandNoise-signalratio
DetectoriscomposedofHAMAMATSUphotomultiplier,soensuregoodaccuracy.
3)Highspeeddatacollection
Self-developedpatentproduct-CR256digitalcorrelation,Itcouldfinishdynamicscatteringlight
intensitycollectionandautocorrelativefunctioncalculation,effectivelyreflectdynamic
scatteringlightinformationofdifferentsizesofparticles.
4)Highstablelightsystem
Photoncorrelationspectrumdetectsystemadoptoptical-fibretechnology,smallersizeandhigh
anti-interferenceandreliability.
5)Highprecisionconstanttemperaturecontrolsystem
Semiconductortemperaturecontroltechnology,precisioncontrolwithin±0.2℃，makesamples
beinaconstantstatethroughoutthetestingprocess,preventtestingerrorbecausetemperature
