    • A system and related method are provided for measuring conductivity/resistivity of water having high purity, including a temperature sensor and a conductivity/resistivity sensor exposed to a water source. The system further includes a computing assembly configured to receive measurement signals from the sensors and to determine change in resistivity over a change in temperature (a collected R/T slope) from the collected temperature measurements and the collected resistivity measurements. The system compares the collected R/T slope to a standardized R/T slope at a temperature value corresponding to a midpoint temperature of the temperature measurements over the prescribed time interval. Based on the comparing, the system provides providing a compensated measurement for resistivity or conductivity of the water source. As a result, the system can calibrate the sensor continually during use, in real time, resulting in highly improved accuracy.
    • 提供了一种用于测量具有高纯度的水的电导率/电阻率的系统和相关方法,包括暴露于水源的温度传感器和电导率/电阻率传感器。 所述系统还包括计算组件,其被配置为从所述传感器接收测量信号,并且根据所收集的温度测量值和所收集的电阻率测量值确定温度变化(所收集的R / T斜率)上的电阻率变化。 该系统将收集的R / T斜率与对应于在规定时间间隔内的温度测量的中点温度的温度值进行比较。 基于比较,该系统提供对水源的电阻率或电导率的补偿测量。 因此,系统可以在使用过程中实时校准传感器,实时提高精度。
