Hardness Tester For Mastic Asphalt

Introduction

Used for determination of Kinematic and intrinsic viscosity of fuels, lubricants & petrochem raw materials at constant temperatures in accordance with ASTM D 445 and other equivalent methods. Available in two versions, to work at above ambient temperature and below ambient temperature.

General Descripation & Specifications :

Double walled, outer chamber made of G.I. - powder coated, with removable toughened Glass window panel, inner chamber made of S. S, FHP motorised stirrer for uniform temperature, Dual Display Microprocessor Based Digital Temp. Controller with PT-100 sensor. Temperature range from 5° C above ambient to 100° C., Control accuracy ± 0.1°C. Below ambient Viscosity Baths are fitted with Refrigeration system (Temperature Range : 10°C to 100°C). The Baths can accommodate 2 / 4 / 8 Viscometers with varying tank volumes.

Reverse Flow Viscometer

The viscometer is made of clear borosilicate glass free from visible defects. All glass tubing used in the construction of a single viscometer is of the same composition and the finished instrument is thoroughly annealed. The design and details of the viscometer are given at side. The size, approximate constant and Kinematic Viscosity is as per table.

Size No. App. Const (cSt/s) Kin. Viscosity
Range (cSt)
4 0.1 6 to 100
5 0.3 18 to 300
6 1.0 60 to 1000
7 3.0 180 to 3000
8 10 600 to 10000
9 30 1800 to 30000
10 100 6000 to 100000
11 300 18000 to 300000
