Introduction:
GDJ-1F Brookfield viscometers is suitable to determine apparent viscosity of highway asphalt at a temperature from 45 °C to 200 °C as per Brookfield Viscometer Rotation Methods. It can also be used to determine construction temperature for bituminous mixture as per viscosity-temperature curve.
Technical parameters:
1. Measurement range: 25mPa?s~1×10000000mPa?s (If purchase the No.30 spindle, its measurement range can be extended to 2×10000000mPa?s);
2. Spindles: four spindles of No.21, 27, 28 and 29 (No.30 spindle is optional);
3. Spindle speed: 0.1~100 RPM continuously adjusted;
4. Measurement error: ± 2% (F?S) (± 3% (F?S) for No.30 spindle);
5. Temperature controlling range: 25°C~200°C;
6. Temperature controlling accuracy: ±0.1°C;
7. Cubage of sample chamber: 20 ml;
8. Power supply: AC 220V±10%, 50 Hz;
9. Ambient temperature: 5°C~35°C (the ambient temperature should be about 5 °C lower than controlling temperature of heater);
10. Relative humidity: not more than 80%.
