DO9100 Dissolved Oxygen Meter and DO Water Tester

Protect aquatic environments by knowing how much oxygen the water contains. The DO9100 measures dissolved oxygen concentration, saturation, and temperature through a portable polarographic probe. Automatic temperature compensation supports stable field readings, while its IP67 housing provides added protection around water. It is designed for aquaculture operators, aquarium keepers, water-treatment staff, laboratories, and environmental testing.

Key Features

• Measures dissolved oxygen from 0.0–30.0 mg/L.
• Displays oxygen saturation from 0.0–300.0%.
• 0.1 mg/L resolution with stated accuracy of ±1.5% full scale.
• Measures temperature from 0–40°C with °C/°F selection.
• Automatic calibration at 100% in air or 0% using oxygen-free water.
• Hold function, low-battery indicator, and automatic shutoff.
• Response time of up to approximately 45 seconds at 20°C.

Perfect For

Ideal for fish farms, aquariums, ponds, hydroponics, wastewater treatment, laboratories, pools, rivers, lakes, and environmental surveys. This aquaculture oxygen testerhelps users monitor aeration and conditions affecting fish and other aquatic life.

How to Use

Prepare and polarize the probe as instructed, then calibrate it in air. Immerse the sensor, move it gently to maintain water flow, and wait for the reading to stabilize.
