GD-265C
GOLD
ASTM D445 Digital Kinematic Viscosity Bath
Summary of Test Method:
The time is measured for a fixed volume of liquid to flow under gravity through the capillary of a calibrated viscometer under a reproducible driving head and at a closely controlled and known temperature. The kinematic viscosity (determined value) is the product of the measured flow time and the calibration constant of the viscometer. Two such determinations are needed from which to calculate a kinematic viscosity result that is the average of two acceptable determined values.
Main technical specification and parameters:
1. Power supply: AC 220V±10%, 50Hz±5%;
2. Heating power: two grades, 1000 W + 600 W;
3. Stirring motor:
(1) Power: 6 W;
(2) Speed: 1200 RPM;
4. Temperature measurement range: room temperature～100℃;
5. Temperature controlling accuracy: ±0.1℃;
6. Constant temperature bath:
(1) Cubage: 20 L;
(2) Types: Two layers glass cylinders;
7. Operation environments:
(1) Ambient temperature: -10℃～+35℃;
(2) Relative humidity: ＜85％;
8. Temperature sensor: Platinum resistance; Pt100;
9. Total power consumption: not more than 1800 W;
10. Capillary viscometer: 7 pieces in total; their diameters are 0.6, 0.8, 1.0, 1.2, 1.5, 2.0, and 2.5 mm respectively.

Instrument structure:
1. Double layers bath
The constant temperature bath of the instrument adopts double layers type. The inner layer is a harden glass cylinder of φ300×300mm and the outer layer is a synthetic glass cylinder of φ360×285mm.
2. Illumination system
There is a lamp installed in the instrument, so that you can observe the reading of capillary viscometer clearly.
3. Temperature controlling system
(1) Temperature sensor: Platinum resistance; Pt100;
(2) Temperature controller: It is a digital and intelligent temperature controller. It can show four digits by double LED. It can control temperature rapidly with short response time and small over-regulation value. Its controlling accuracy can be ±0.1℃.
(3) Heating system: It uses heater of 1000 W and 600 W for heating, so the temperature can increase quickly. It can adjust the heating power when the temperature is close to the preset temperature, so that it can keep the bath temperature stable.
4. Stirring system
The stirring motor is a 60YN06-2B non-slowdown, single phase asynchronous motor. The heating and stirrer are both in the protection shield.
