Sper Scientific 850045 DO Pen

Dissolved oxygen (DO) is one of the most important indicators of water quality. It is essential for the survival of fish and other aquatic organisms and is used in hydroponics as well. When dissolved oxygen becomes too low, fish and other aquatic organisms cannot survive. Sper Scientific dissolved oxygen meters are made to accommodate the user with rugged, portable meters for use out in the field. All of our DO meters offer fast and accurate DO response times in wastewater, surface water and aquaculture applications. Three basic styles of DO meters are available for varying applications: Pens, Portable Meters, and Multi-parameter meters.

Easy to carry, simple to calibrate and use
Sufficient for many surface dissolved oxygen measurements

Measures dissolved oxygen to determine water quality in environmental testing, labs, industrial and municipal waste water, aquariums and fish hatcheries. Designed for simple one-hand operation with automatic temperature compensation and calibration to air. The polarographic probe has a built in temperature sensor and easy-to-replace pop-off probe heads. Simultaneously displays dissolved oxygen and temperature readings. Also holds readings and recalls minimum and maximum. IP67 waterproof, floats if accidentally dropped in water. Comes ready to use in a soft carrying case with belt loop, two spare probe heads, electrolyte and 4 AAA batteries.
