KN-445Z-2 Full Automatic Kinematic Viscosity Tester

Overview

   KN-445Z-2 Automatic Kinematic Viscosity Tester conforms the ASTM D445 Standard Test Method for Kinematic Viscosity of Transparent and Opaque Liquids (and Calculation of Dynamic Viscosity). It is used to test the of liquid petroleum products, both transparent and opaque, by measuring the time for a volume of liquid to flow under gravity through a calibrated glass capillary viscometer. The dynamic viscosity, η, can be obtained by multiplying the kinematic viscosity, ν, by the density, ρ, of the liquid. Under certain constant temperature. The range of kinematic viscosities covered by this apparatus method is from 0.2 to 300 000 mm²/s at all temperatures.

Features

1.        Double-layer bath design, be able to maintain a much more constant temperature from 20-100℃±0.01℃ with 0.01℃ resolution. Using 10# methyl silicone oil as the bath medium, it can be used for a long time without replacement.

2.        Adopts ARM single-chip microcomputer to control the temperature and viscosity testing, so that make the test results are more accurate. Using Windows 7 operating system, full English/Russian operation language, convenient for operation, providing a variety of communication interfaces (RS-232, USB and RJ-45, etc.), can be connected to LIMS system and WLAN.

3.        Wide kinematic viscosity measurement range, each viscometer adopts two detection bubble design, with 20 times the viscosity measurement range. Every tester is equipped with one calibrated viscometer, the software also has the calibration function, it is able to calibrate the viscometer by the operator for a wider measuring range.

4.        Full automatic cleaning process, no need manually operation

5.        One PC is able to connect 1~4 testers for operation simultaneously
