Absolute Kinematic Viscosity Bath - Glass Material, Digital Temperature Control, Range 37.8-82 C, Accuracy 0.1 C, Vacuum System 0.05 Cm | Key Features: Precise Control, Digital Display, Thermometer, Stopwatch

The following testing equipments are used to measure absolute viscosity of viscosity graded paving bitumen (IS:73:2006) at 60A C in accordance with IS:1206 (Part II) (similar to ASTM D 2171), which uses a vacuum capillary viscometer. It may please be noted that any other viscometer such as rotational viscometer cannot be used to measure the absolute viscosity at 60A C since the bitumen in non Newtonian in nature at this temperature.
Complete Absolute Viscosity Testing Equipment conforming to IS: 1206 (Part II) Method for Testing Tar and Bitumen Materials: Determination of Absolute Viscosity with the following components:
Constant Temperature Bath: A suitable bath for immersion of at least 2 vacuum capillary viscometer tubes with a digital temperature controller. The accuracy of the temperature in the bath will be A 0.1A C throughout the bath.
Vacuum System: Capable of maintaining a vacuum within A 0.05 cm of the desired level The system will consist of vacuum pump, moisture trap, vacuum regulator, bleed valve, all interconnecting tubing/ piping, and any other accessory as needed to complete the vacuum system.
Thermometer for Bath: Mercury in glass, range 37.8 to 82A C, and graduations of 0.2A C.
Timing Device: A stop watch or stop clock capable of reading up to A second.
