Its polarographic probe, temperature compensation, and air calibration support convenient field or bench testing. The pen-style meter travels easily between tanks, ponds, and sampling locations.

Key Features

  • Reads oxygen in mg/L or saturation percentage
  • 0.1 mg/L measurement resolution
  • Automatic temperature compensation
  • Hold, low-battery warning, and automatic shutoff

Perfect For

Ideal for marine and freshwater aquariums, fish farms, ponds, hatcheries, laboratories, wastewater checks, and environmental sampling.

How to Use

Fill and assemble the electrode as instructed, allow it to polarize, then calibrate in air. Immerse the probe, maintain gentle water movement, and wait for a stable reading. Rinse after use and inspect the membrane regularly. Apply salinity or altitude corrections when needed.
