Standard Tar Viscometer
Product Code : JA-ALI-1707
The Standard Tar Viscometer (SKU JA-ALI-1707) is used to determine the viscosity of cut back bitumen and road oil by timing their flow through an orifice cup at a controlled temperature. JaincoLab supplies this standard tar viscometer with electric heating and a choice of 10 mm or 4 mm cup, for highway and road-materials laboratories, bitumen plants and the transportation engineering laboratories of civil engineering colleges.
Specifications
The viscometer has a chrome-plated copper bath with a drain valve and a central tube that holds the test cup and positions the stirrer, on a stand with levelling feet; it is heated by immersion heating elements with a Dimmerstat and runs on a 220 V, 50 Hz, single-phase AC supply.
