CAL检查以验证仪表性能该HI97101提供一米内的多种方法。、氙和碘的测定使用DPD法:铁的测定使用TPTZ法的改进版:pH的测定使用酚红法;氰尿酸的测定使用浊度法的改进版。根据被测参数的不同，试剂有粉末状和液体状。
氯是房主、酒店和商业企业最常用的水消毒剂。在游泳池，水疗中心，和类似的应用，氰尿酸有助于稳定氯和防止其分解，特别是在阳光下。频繁检测三聚氰酸和pH值有助于减少氣的消耗。溴和碘的消毒特性导致它们被用作氯的替代品。碘最常见的应用之一是家禽业的生产用水，而溴则用于冷却塔、水池和温泉的消毒。
当在样品中加入合适的试剂时，会显示出颜色的变化;浓度越大，颜色越深。然后根据Beer-Lambert定律对相关的颜色变化进行比色分析。这-原理指出，光被补色吸收，而发出的辐射取决于浓度。对于所有六个参数的测定，在525nm(绿色)的窄带干涉滤光片，只允许绿光被检测到的硅光电探测器和省略所有其他可见光从钨丝灯发出。随着反应后的样品的颜色变化增加，特定波长的光的吸光度也增加，而透射率降低。技术参数：
