Standard Tar viscometer is used for determining the viscosity of cut-back bitumen and road oil.
81-B0122/C: Digital Standard Tar viscometer. 230 V, 50-60 Hz, 1 ph
The apparatus, housed in a stainless steel case, consists of a tank fit with a thermostat, a rheostat, an agitator, an immersion heater to take the water to the required temperature and cooling coil for connection to the water supply.
The temperature is checked by a 0-45°C thermometer.
Cups, thermometer and Go/Not go gauge have to be ordered separately.
