Product Description

Purpose:
The instrument is designed and made as per T***5 in the Industry Standard JTJ**2 Specification and Test Methods for Bitumen and Bituminous Mixtures for Highway Engineering, and ASTM D***2. It has a very wide range of functions. First of all, it is suitable to determine apparent viscosity of highway asphalt at a temperature from *5 ℃ to **0 ℃ as per Brookfield Viscometer Rotation Methods. And then, it can be used to determine construction temperature for bituminous mixture as per viscosity-temperature curve. At last also it can be used to determine viscosity of hot melt adhesive, oil grease, paraffin and high polymer. It can be widely used in cosmetics, food, pharmaceutical, dopes, chemical, and other industries.
 
Technical parameters:
1. Relative humidity: not more than *0%.
2. Power supply: AC **0V±*0%, *0 Hz;
3. Spindle speed: 0.1~**0 RPM continuously adjusted;
4. Measurement error: ± 2% (F•S) (± 3% (F•S) for No.*0 spindle);
5. Temperature controlling range: *5℃~**0℃;
6. Temperature controlling accuracy: ±0.1℃;
7. Cubage of sample chamber: *0 ml;
8. Spindles: four spindles of No.*1, *7, *8 and *9 (No.*0 spindle is optional);
9. Ambient temperature: 5℃~*5℃ (the ambient temperature should be about 5 ℃ lower than controlling temperature of heater);
*0. Measurement range: *5mPa•s~1×*******0mPa•s (If purchase the No.*0 spindle, its measurement range can be extended to 2×*******0mPa•s);
