Optical Dissolved Oxygen Meter

光学溶解氧仪

Aeration control, long-term monitoring and aquaculture systems benefit from luminescent DO sensors that need no membrane or electrolyte. This optical meter reads 0–20 mg/L at ±0.1 mg/L or ±1% of reading, consumes no oxygen and so needs no stirring, and typically calibrates every 1–6 months. Response is ≤60 s. Tell us your installation type.
