LCR 7000 - Dynisco 毛细管流变仪 Capillary Rheometer产品描述

通用性

新款LCR7000系列毛细管流变仪的众多新功能，可满足每天24小时的车间运行要求，同时尽可能维持最高水平的准确性、重复精度和灵敏性。LCR系列流变仪为通用型，易于使用，具备最精密复杂的材料特性分析、数据分析和报告功能，并且可与标准称重传感器和安装了压力传感器的机筒配合使用。

成熟的软件

LAB KARS（“Kayeness先进的流变学软件”）是市面上最强大和易于使用的、以Windows™为运行平台的流变学软件包。其易于使用的功能包括：Bagley和Rabinowitsch校正，加上幂次法则、卡罗流体模型、Modified Cross和多项式粘度模型。通过此软件，用户能够合并剪应力、剪切速率或热稳定性测试等多个数据文件。内嵌的KARS SQC模块可用于快速识别不同批次材料的粘度变化。同时还包括测量PET（聚酯）和尼龙特性粘度与熔体粘度之间关联的程序。

实时显示

除其他所有强大功能外，用于Windows™环境的LAB KARS能够在测试过程中实时显示力或压力随时间变化的情况。此功能允许操作人员确定材料的稳定态流动状况。另外，污染、未熔融的树脂或材料中的气泡，都可从压力与时间曲线中的尖峰处识别出来。

Description

Versatile

The new LCR7000 Series Capillary Rheometers offer many new features and will meet the demands of a 24-hour-a-day shop floor operation while maintaining the highest possible level of accuracy, repeatability and sensitivity. The LCR series rheometers are versatile and easy to use yet they offer the most sophisticated materials characterization, data analysis, and reporting capabilities. The LCR series can be used with a standard load cell and a barrel mounted pressure transducer.

Sophisticated Software

LAB KARS (“Kayeness Advanced Rheology Software”) is the most powerful and easy to use rheological Windows™-based software package available. Just a few of its easily useable features include: Bagley and Rabinowitsch Corrections plus power law, Carreau, Modified Cross and polynomial viscosity models. With this software users can merge multiple data files from shear stress, shear rate, or thermal stability tests. The resident KARS SQC module can be used to quickly identify viscosity variations in different lots of material. A program for the correlation of melt viscosity to intrinsic viscosity, for PET and Nylon, is also included.

Real-Time Display

In addition to all of its other powerful features LAB KARS for Windows™ provides a real time display of force or pressure versus time as a test progresses. This feature allows the operator to identify the steady state flow condition for the material. In addition, the presence of contamination, unmelted resin, or bubbles in the material may be identified from spikes in the force versus time curve.
