Valid, Reliable. Reputable.
The efficient design of the Standard Tar Viscometer (STV) guarantees compliance with EN 12846-1, EN 12876-2, EN 13357, and IP 72 requirements, addressing all cut-back bitumen viscosity testing needs.
Designed with safety in mind, the stainless steel, open jacket viscosity bath is equipped with digital temperature regulation, over temperature alarm, an insulated double wall, and motorized agitator. A single gage fill point, visible from the outside of the standard tar viscometer, allows for easy fill without overflow while the internal light indicator alerts to low liquid levels. The stainless steel electric heating component and cooling coil allow for quick boiling and cooling of liquids, because your time is valuable.
The STV is available in models 140, 140/2 (2 positions), 140/3 (3 positions), and 140/4 (4 positions). The viscometer accurately determines the time of efflux of 50 ml of cutback bitumen, at 40-60ºC, via a 10 mm orifice, at a range of 15-500 seconds. With a capacity of approximately 7 liters, the 11 kg STV is equipped with brass oil cup with closing-ball ended rod to deliver accurate results. The in-bath drain valve provides for easy post-test drainage of liquids, making cleanup a breeze.
