纱线测湿仪
YG201型数字式测温、测湿、数字显示一体化多用纱线测湿仪是一种快速测湿仪，可测量棉纱线筒子、混纺纱筒子及有关化纤线的回潮率。
本仪器是一种电阻法测湿仪，试样电阻范围为：3.8×104Ω～2×1012Ω。本仪器结构紧凑、性能稳定、测湿范围宽
原理与结构
纤维的物理电气性能
棉、粘胶、涤纶等纤维及其在制品，在常态下均有一定水份，因此它们均有一定的导电特性，其电阻值与含水量有一定的对应关系。纤维吸湿量用回潮率表示，试样的回潮率高，其电阻值小；试样的回潮率低，其电阻值大。在一定的条件下，对试样加一定的测量电压，就可以通过使用测量流过试样的电流的方法，来计算试样的回潮率。试样的电阻值除与回潮率有关外，还受温度等因素影响。仪器通过测量温度来修正回潮率读数。
结构
仪器由回潮率测量仪和温度测量仪两部分组成。回潮率测量仪有回潮率量程选择开关、及测湿传感器探头组成。温度测量仪有测温传感器探针，温度测量显示电路组成。
