    • 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,包括温度传感器和暴露于水源的电导率/电阻率传感器。 该系统还包括计算组件,该计算组件被配置为接收来自传感器的测量信号并且根据收集的温度测量结果和收集的电阻率测量结果来确定温度变化(收集的R / T斜率)上电阻率的变化。 该系统将所收集的R / T斜率与在规定时间间隔内与温度测量的中点温度相对应的温度值的标准化R / T斜率进行比较。 基于该比较,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,从而实现高度精确的测量。
