水质在线监测仪校准常识介绍!

Time:2020-11-27     Author:北中科技   Read

      有人可能会问,为什么要对水质在线监测仪进行校准呢?其实原因很简单,因为检测设备的校准是和测量数据有很大的关系的,如果不及时校准会导致检测结果的误差越来越大。本章水质在线监测仪厂家将来和大家一起了解水质在线监测设备校准的问题。


  当仪器使用时间长了,仪器检测数据就很有可能出现误差。例如:PH传感器上的玻璃表面微小物理变化将改变响应并导致不准确的pH读数。然而校准能抵消这些水质在线监测设备的变化。另外在使用单一校准水质在线监测设备时,必须要使用和水质标准接近的值,距离标准值越远的话,水质在线监测仪器工业的数据准确度就会越低。决定结果不准确的因素成为线性的特征,一般指的是随着浓度的变化,仪器的响应会出现变化。

      但是如果,并非所有水质在线监测设备和分析物都具备线性行为的,而且并不是所有仪器在所有范围都是线性的。通常线性度略有不同,这些是决定有效校准的重要原因。如果设备在一个范围内容没有表现出线性行为,那么就要选择两个紧密包围预期值的校准标准,这样会抵消由非线性产生的不准确。


  总而言之,用于校准设备的浓度和点数将对水质在线监测仪结果产生一定的影响,所以用户要对其设备进行定期校准。
