The Tamson ASTM D2171 apparatus is an excellent solution to test the viscosity of bitumen by vacuum capillary viscometer. The TV4000 can be used together with the Tamson Vacuum System (TVS) and Tamson Vacuum Manifold (TVM) to do viscosity determinations at +60°C according to ASTM D2171, IP 222, EN/ISO 12596 and AASHTOT 202. The apparatus offers four positions for Cannon Manning Vacuum Viscometers (CMVV), Asphalt Institute Vacuum Viscometers (AIVV) and Modified Koppers Vacuum Viscometers (MKVV).
The TV4000 is able to achieve a temperature stability of 0.01°C. All wetted parts are made of stainless steel and brass, providing resistance against all usual bath fluids. The bath is fitted with adjustable feet for leveling. The bath is equipped with two windows.
The TV4000 is maintenance free and designed to run with minimal operational costs. The TV4000 can be operated from ambient +5 up to +230°C (..446°F). With the use of the built-in cooling coil, sub ambient temperatures down to +5°C can be achieved. The bath is equipped with both a drain and an overflow outlet. Also the viscosity bath is equipped with a float that will switch off the bath when the level of the bath fluid is too low. The bath conforms to CE-regulation. Further the bath is equipped with a mechanical over temperature protection. Optionally, the bath can be equipped with a Z41 backpanel illuminator to improve visibility.
