Dissolved Oxygen
Waterproof Dissolved Oxygen Meter Pen
Measures dissolved oxygen to determine water quality in environmental testing, labs, industrial and municipal wastewater, 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. IP65 waterproof. Comes ready to use in a soft carrying case with belt loop, two spare probe heads, electrolyte and 4 AAA batteries. EPA Equivalency Method: 360.1

Dissolved Oxygen Meter Kit
Reliable DO readings at a reasonable price
Measures dissolved oxygen to determine water quality in environmental testing, labs, industrial and municipal waste water, aquariums and fish hatcheries. The back-lit display simultaneously displays dissolved oxygen (in % or mg/L) and temperature readings (in °C or °F). Automatic temperature compensation as well as manual compensation for salinity and altitude. Features simple one-button calibration to air. DO probe heads include built in membranes and screw on and off for easy replacement. Also functions as a pH, ORP, Conductivity, TDS or Salinity meter when used with the optional probes (sold separately).
Comes in a hard carrying case complete with one DO probe, two spare probe heads, electrolyte, instructions and a 9V battery.

Water Quality Meter Kit
Interchangeable plug and play probes let this versatile meter read pH, mV, ORP, conductivity, salinity, TDS, DO and temperature.
Order probes only for parameters currently required, and add additional probes in the future. The back-lit display simultaneously reads temperature in user selectable °C & °F. All measurements are automatically temperature compensated. DO measurements can be compensated for salinity, while Oxygen in Air (O2) can be compensated for altitude.
Automatic calibration recognition of pH buffers 4, 7 and 10. Also features auto power off, hold, min/max, fold-out easel back and a tripod screw. Comes with 9V battery and hard-shell, foam-lined carrying case with room for one or two probes (not included). EPA Equivalency Method: 360.1 and Alpha Method 2580.1992.
