A portable automatic capillary viscometer, equipped with an AVR microcontroller, was designed and developed. The viscometer was calibrated with Certified Reference Material (CRM) s200 and utilized for measurement of kinematic viscosity. A quadratic equation was developed for calibration of the instrument at various temperatures. Also, a model was developed for viscosity determination in terms of the viscometer dimensions. Development of the portable viscometer provides for on-site monitoring of engine oil viscosity.
设计并开发了一种配备AVR微控制器的便携式自动毛细管粘度计。该粘度计使用标准参考物质（CRM）s200进行校准，并用于测量运动粘度。开发了一个二次方程用于在不同温度下校准仪器。此外，还根据粘度计尺寸开发了一个粘度测定模型。便携式粘度计的开发实现了对发动机油粘度的现场监测。
