这款四合一分析仪通过一台手持仪器即可测量臭氧、游离/总氯与二氧化氯，量程覆盖臭氧 0-2.50 mg/L、游离/总氯 0-3.00 mg/L、二氧化氯 0-5.00 mg/L，读数分度均为 0.01 mg/L。525 nm LED 光源配合试剂化学，支持现场快速消毒剂余量核查。
它由 4 节 AAA 电池供电，带 LCD 背光，重量约 220 g，便于在野外、工厂与实验室之间转移。显色反应计时结束后直接读数，无需标准曲线。
它覆盖哪些参数？
臭氧（0-2.50 mg/L）、游离/总氯（0-3.00 mg/L）与二氧化氯（0-5.00 mg/L），均在一台设备上完成。
需要标准曲线吗？
不需要。它依据所选测试的单参数试剂定时显色反应直接读数。
便携性如何？
4 节 AAA 电池、LCD 背光、约 220 g 重量，可在野外、工厂与实验室间移动。
读数分度是多少？
三个参数均为 0.01 mg/L，可分辨微小的余量变化。
