I.Introduction

• GD-265E Petroleum Products Viscosity Tester /Capillary viscometer

• The Asphalt Kinematic Viscosity Testis designed and made as per the T0619 "Asphalt Kinematic Viscosity Test (Capillary Viscometer Methods" in the Industry Standard JTJ052 Specification and Test Methods of Bitumen and Bituminous Mixture for Highway Engineering. It is suitable to determine kinematic viscosity of asphalt at a certain temperature.

 

II.Technical parameters

1. Power supply: AC 220V±10%, 50 Hz;

2. Heating power: two grades; 1000 W for auxiliary heating and 600 W for temperature controlling;

3. Bath temperature: ambient temperature~180.0°C;

4. Temperature controlling accuracy:  ±0.1°C;

5. Mercury thermometer:

(1) Rod type

(2) Scale division: 0.1 °C;

(3) Measurement range: 100~150°C or 150~200°C;

6. Bath cubage: not less than 23 L;

12. Total Power consumption: not more than 1800 W.

13. Capillary viscometer: 7 pieces of Cannon-Fenske reserve-flow capillary viscometer tubes in a group; their models are 200, 300, 350, 400, 450, 500, 600 respectively (Corresponding diameters are 1.02, 1.26, 1.48, 1.88, 2.20, 3.10 and 4.00 mm). The users should prepare Ubbelohde type viscometer tubes by themselves.

 

III.Characteristics 

1. GD-265E bitumen/asphalt kinematic viscometer is mounted with digital temperature controller

2. The temperature controlling precision is ±0.01°C.

3. The testing bath is made of hard glass, equiped with electric stiriing device, that can keep the equilibrium temperature in the bath.

4. Two bases, inner and outer bath, could keep a good heating reservation.
