A: The measurement range of the instrument is 100mPa.s to 200,000mPa.s. It operates with a measurement error of ±3% F.S. and maintains a high temperature control accuracy of ±0.1℃.
A: The unit comes standard with a 27# rotor, with optional 21#, 28#, and 29# rotors available. The speed settings can be configured to 5 rpm, 10 rpm, 20 rpm, or 50 rpm.
A: It must be installed on a stable workbench in an area free from corrosive gases, strong electromagnetic interference, and mechanical vibrations to ensure proper function and data accuracy.
A: Place the rotor and sample tube together in a temperature-controlled oven for pre-insulation. The asphalt sample must be kept in the constant temperature container of the viscometer for at least 15 minutes to reach the required equilibrium temperature before testing begins.
A: The torque reading of the Brookfield rotational viscometer should be maintained within the range of 10% to 98%. For road asphalt, control the torque between 20% and 70%. For modified asphalt, maintain it at approximately 50%.
A: Clean and dry the measuring device and inner wall of the rotating drum before and after each use. Store the instrument in a dry environment to avoid moisture damage, and never disassemble internal parts or the hairspring yourself.
