Description

The Wireless Optical Dissolved Oxygen (ODO) Sensor is the perfect solution to monitor DO in the lab or the field. Optical technology is accurate, fast, and does not need flow or calibration.

The Wireless Optical Dissolved Oxygen (ODO) Sensor actually contains three different probes. In addition to dissolved oxygen, there are also probes for atmospheric pressure and the water temperature.

A PASCO exclusive feature allows you to log data using the sensor’s built-in memory. After hours or even days, connect the sensor to your device and download the data. You can capture day/night nutrient cycles, changes in metabolic processes and more.

With the included cover, the sensor has a waterproof design and is submersible to 10 m.

No need for an interface.

All PASCO Wireless Sensors connect to computers, Chromebooks, and tablets, through Bluetooth 4. No other equipment required! Our software (SPARKvue or PASCO Capstone) allows students to see and analyze data in real-time.

Long-lasting, rechargeable battery

The Wireless Optical Dissolved Oxygen Sensor draws as little current as possible. This provides you with a long battery life for lab activities. Our software also displays the battery level at all times. If it dips too low, connect the USB cable to charge while you collect data.

Freshwater Quality Monitoring

In this lab, students assess the local water quality using measurements from pH, conductivity, temperature, dissolved oxygen, and turbidity sensors.

What Factors Affect Dissolved Oxygen?

Students will use a dissolved oxygen sensor to determine how different factors affect the concentration of dissolved oxygen in water.

Monitoring Water Quality

In this lab, students use a water quality sensor, turbidity sensor, and weather/anemometer sensor to monitor the pH, dissolved oxygen content, conductivity, and turbidity of a natural body of water. Students will use their data…

Modeling an Ecosystem

In this lab, students will design and study three, small ecosystems. Students will manipulate system interactions while monitoring gas exchange, environmental conditions, and subject health.

Photosynthesis and Primary Productivity

In this lab, students use a dissolved oxygen sensor to determine the primary productivity of an aquatic plant.
