It can be used for the determination of dissolved oxygen in water bodies, such as tap water monitoring, aquaculture farm, environmental protection, sewage treatment plant, beverage industry and scientific research units etc. The instrument is novel in shape and easy to carry, suitable for field and field operation. Long, can be used as a routine laboratory analysis equipment.
