The petroleum viscosity measurer can measure and display one or a plurality of viscosity values of any given temperature once at any inconstant temperature.

本石油粘度测定仪，可以在任意非恒定温度下，一次测得一个或数个任意给定温度下的粘度值，并显示出来。

Using the temperature sensor AD590 and humidity sensor HM1500, and the A/D converter CC7107 etc. A low power and low cost measurer of temperature and humidity was designed.

采用温度传感器AD590、湿度传感器HM1500、A/D转换器CC7107以及少量常用元器件，设计并制作了一款低功耗、低成本的数字显示温湿度两用测量仪。

The measurer in - crease the system precision by distribute ten section for linear the not linear between temperature and thermoelectric.

采用分段(每十度分段)对温度一热电势间非线性关系的线性化，提高了系统的测温精度。
