Dissolved oxygen is vital to many aquatic species including fish and other aquatic organisms. When dissolved oxygen levels are too low water becomes stagnant and it can result in large numbers of fish kills. Water is oxygenated through aquatic plant photosynthesis, rain, streams and from the air.

Knowing this concentration can be the difference between a healthy aquarium, fish farm, pond or aquatic environment. Lab applications of dissolved oxygen meters are easily met by this highly accurate instrument. Featuring a long cable attached to the measurement probe gives more versatility and measurement ability. Great for measuring streams, ponds and aquariums which might be hard to access. The 407510 Heavy Duty Dissolved Oxygen Meter User Manual is attached to this page to answer any additional questions.
