Brief Introduction

DSVDilute solution viscosity meter/Y501 relative viscosity meterIt is the earliest to provide comprehensive services to customersViscosity testing system. Whether you need a manual detection system for limited sample size testing or a fully automated injection detection system for high-throughput, safe, and highly reproducible testing, DSV can meet your needs.

Unlike the glass capillary viscometer, which detects the time it takes for a solution to pass through the capillary,the United StatesHMJcompanyDSVThe dilute solution viscometer uses pressure changes to detect relative viscosity. Two capillaries are connected in series, and the injection valve is located on both capillaries 1 and 2 middle The differential pressure sensor detects the pressure drop at both ends of each capillary tube. When the sample is injected into the second capillary, the differential pressure sensor detects the capillary2Changes in pressure on top (Figure)3）. Relative viscosity is equal to the ratio of two capillary pressure drops multiplied by the instrument constantK.

Due to the high sensitivity of the relative viscometer, it is only necessary to detect a sufficiently diluted solution to directly obtain the desired viscosity without extrapolating from the United StatesHMJcompanyDSVThe dilute solution viscosity meter provides an accurate and high-precision method for fully automatic detection of solution viscosity.
