DOZ201 是一款手持式比色计,专用于单参数臭氧(O3)测量,量程 0-2.50 mg/L、读数分度 0.01 mg/L。525 nm LED 光源配合试剂化学,是饮用水、食品及低浓度臭氧消毒核查的实用工具。
仪器由 4 节 AAA 电池供电,可连续工作 40 小时以上,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,操作人员无需绘制标准曲线。
DOZ201 需要标准曲线吗?
不需要。它依据单参数试剂的定时显色反应直接读数,操作人员无需建立或保存曲线。
最低可显示多少?
读数分度为 0.01 mg/L,因此在 0-2.50 mg/L 量程内可分辨小至 0.01 mg/L 的变化。
野外电池能用多久?
4 节 AAA 电池可连续工作 40 小时以上,足以支撑长时间野外或倒班使用。
能测氯或二氧化氯吗?
不能。DOZ201 仅针对臭氧;多参数分析仪才覆盖氯与二氧化氯。
