Product Name:        GDJ-1D ASTM D4402 Brookfield Rotation Viscosity Meter

Measurement Standards:

1. JTJ052 Specification and Test Methods for Bitumen and Bituminous Mixtures for Highway Engineering.

2. ASTM D4402.

 Introduction: 

The rotational viscometer 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.

Application Scope:

1. Hot melt adhesives.

2. Oil grease.

3. Paraffin.

4. High polymer.

5. Cosmetics.

6. Food.

7. Pharmaceutical.

8. Dopes.

9. Chemical.

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: ± 1% (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.
