Purpose: The instrument is designed and made as per T0625 "Asphalt Rotation Viscosity Test (Brookfield Viscometer Methods)" in the Industry Standard JTJ052 Specification and Test Methods of Bitumen and Bituminous Mixture for Highway Engineering. It is suitable to determine absolute viscosity of Newton liquids and apparent viscosity of non-Newton liquids. It is sensitive, reliable, convenient, beautiful, and it only needs little sample. It can be widely used to determine viscosity of asphalt, hot melt adhesive, paraffin, high polymer, and other liquids. Technical parameters 1. Measurement range: 100 mPa·s~2×105 mPa·s (If you select the No.30 spindle, the measurement range can be extended to 4×105 mPa·s); 2. Spindle: No.21, 27, 28 and 29 total 4 pieces of spindles (the No.30 spindle is optional); 3. Rotation speed: 5RPM, 10 RPM, 20 RPM, and 50 RPM; 4. Measurement error: ±2% (F·S); (If you select the No.30 spindle, it will be ±3% (F·S)); 5. Temperature controlling range: 45 ºC~200 ºC; 6. Temperature controlling accuracy: ±0.1 ºC; 7. Sample cylinder: 20 ml; 8. Power supply: AC 220V±10%, 50 Hz; 9. Ambient temperature: 5 ºC~35 ºC (when the controlling temperature is close to ambient temperature, please run the air conditioner to let the ambient temperature be 5 ºC lower than the controlling temperature); 10. Relative humidity: not more than 80%.
