介绍：T550是一款旋转粘度计，用于精确、快速、方便的测量粘度以及液体和半固体样品的流动行为。所有结果如粘度、剪切应力、剪切速率、屈服应力以及温度等都会在液晶屏上显示。VT550粘度计还可以使用哈克旋转流变仪专用软件RheoWin来实现电脑控制及数据打印输出。VT550粘度计可以测量从稀薄的油、油漆或陶瓷悬浮体至粘稠的奶油、药膏等膏体或聚氯乙烯溶胶,甚至一些其他要求也可以完成，如自动定性非牛顿流体的流动行为、用控制形变模式（CD）定义屈服应力等。10个预先设定的日常程序的任何一个都可以被精确地执行。
主要特点：
1）测量绝对粘度值；
2）软件可以绘制流动曲线、粘温曲线、时间曲线、触变曲线等；
3）既可便携至现场测量也可以在实验室做研究工作；
4）CD模式精确测量屈服应力；
5）可以配锥/板或平行板测量系统。
Introduction:HAAKE™ Viscotester™ 550 Rotational ViscometerMeasure precisely, quickly and simply the viscosity and flow behavior of liquid and semi-solid test materials using the Thermo Scientific™ HAAKE™ Viscotester™ 550.
The HAAKE Viscotester 550 is a Searle rotational viscometer for quality control applications. It is designed with a rotational speed preset and measures the flow resistance of a sample. The torque maintaining the set speed is proportional to the viscosity, so all final information on the viscosity, shear stress and the shear rate is calculated from the torque required, the set speed and the geometry factors of the applied sensor. The results are displayed digitally and can be printed.
Features:
1) Step motor with up to 100 predefined speeds
2) Viscosity measurements according to DIN 53019/ISO 3219
3) Measurement capabilities for substances with small particles (<0.3 mm)
4) Time measurements, automatic recording of flow curves, temperature programs (with optional circulator), CD-method (preset deformation) for determination of yield point
5) Measurements performed manually (push button), internally via programmed methods or computer controlled (with optional accessory)
6) Printable results via RS-232 interface
7) Interchangeable rotors for medium and high viscous products
