For viscosity, OptiMVD complies with ASTM D7945, a method to measure the dynamic viscosity of a liquid using PAC’s patented, field-proven technology. The instrument incorporates a capillary tube enclosed horizontally in a thermal block, which is maintained at a constant temperature by thermoelectric coolers. The test specimen is pushed across the capillary tube by a constant, regulated pressure of compressed air. As the test sample flows past an array of optical detectors, the transit time is measured. Dynamic viscosity is converted to kinematic viscosity using the density of the liquid, measured by the internal digital density meter, which complies with ASTM D7777. By design, the instrument provides exceptionally accurate determination of viscosity and density in petroleum products between +15°C and +100°C through very tight temperature control.
三种可自定义的模型配置中的每一个都加载样品，执行粘度和密度测量，并自动清洁系统。所有配置在40°C时测量粘度范围从1mm² /sec到2,000mm² /sec的样品。在双模型配置中，OptimVD在短短10分钟的一次测试中测量两个独特温度下的粘度，除了使用来自同一小瓶的样品的粘度和密度结果外，还报告了粘度指数（VI）。此外，双配置允许一次编程最多48个样本。
除了小型，快速且高度准确外，OptimVD还易于使用。操作仪器只需要简单的努力将样品加载到加热的样品注入端口或加热的旋转木马中。13.3英寸的颜色触摸屏接口仅需要一些交互来编程测试并开始运行。可以快速完成校准和仪器更新，数据下载是通过USB端口快速简单的过程。真实
cycle time of as little as 10 minutes, OptiMVD is the fastest viscometer/densitometer available today, with precision that is unmatched by other comparable instruments in its class.
该产品的每个方面都是围绕最终用户的便利和工作而设计的。OptimVD凭借其创新的智能样本顺序功能，评估了样品数量，样本顺序，测试温度以及任何用户定义的优先级选择，以确定最有效的测试顺序。对于运行多种温度的完整旋转木马，智能样品订单的内置智能可将总测试时间减少多达50％。
OptimVD是一个完全独立的系统。它不需要在外部冷却或加热浴场上进行额外的投资。它还具有低消耗量的要求，设计用于低能用途来支持环境可持续性工作，当与快速周期的时间和低清洁溶剂使用情况结合使用时，它将转化为总拥有成本较低。
“We listened to our customers and watched how they work, and then developed a viscometer/density meter instrument that delivers high precision and fast analysis times. It is also easy to use, has low cost of ownership and high uptimes, and is packed with labor-saving features in a package that minimizes the use of benchtop real estate,”said Dr. Larry Spino, Group Product Manager at PAC.“ OptimVD是从头开始设计的，并考虑到最终用户。它本质上是灵活的，可以满足具有独特要求的实验室的需求。例如，用户可以在两个不同的温度下从同一小瓶中测试样品，他们可以按任何顺序从任何一个旋转木马中测试样品。这样可以确保高水平的运营效率。将其与总拥有成本较低相结合，而OptimVD在行业中确实是无与伦比的。”
Designed for the challenges of an industrial lab environment, OptiMVD offers speed, precision, and low cost of ownership. By employing digital automation technologies, it increases test productivity and improves repeatability and reproducibility.
