DO100 是一款笔式溶解氧测量仪,服务最依赖溶解氧的人群:鱼虾养殖户。同一份样品可读出两种氧含量表示——0.00–20.00 mg/L 和 0.0–200.0 % 饱和度——分辨率 0.01 mg/L / 0.1 %,精度 ±2 % F.S.。
可更换的原电池(伽伐尼)式溶解氧电极无需极化等待,日常使用也无需用户更换膜片;校准为 1 点或 2 点程序,对照无氧溶液或饱和空气进行。90 g 笔身防护等级 IP67,单节 AAA 电池供电。
mg/L 与 % 饱和度有什么区别?
mg/L 是每升水中氧的重量;% 饱和度是把这个值与当前温度、气压和盐度下的理论最大值比较。两种视角来自同一次测量。
电极可更换吗?需要换膜吗?
DO100 采用可更换的原电池式电极,设计上日常使用无需换膜——电极本体寿命到后直接更换电极即可。
两个校准点分别代表什么?
1 点程序用 100 % 饱和氧(潮湿空气)校准;可选的第 2 点用 0 % 无氧溶液。校准点越多全量程越准,但并非每次池塘检测都需要。
为什么放苗或投喂前要关注溶解氧?
低溶解氧会让鱼虾产生应激、生长变慢,夜间甚至导致死亡。笔式快测能让你在行动前确认溶氧是否充足、曝气时机是否合适。
