This probe combines the power of multiple sensors to measure dissolved oxygen, water temperature, and atmospheric pressure. Ideal for experiments in biology, ecology, and environmental science courses, the probe uses luminescent technology to provide fast, easy, and accurate results. Perfect for field or laboratory, it requires no calibration, no filling solution, no warmup time, and no stirring. Rechargeable battery offers long battery life. Includes micro USB cable.

Product Details
The Go Direct® Optical Dissolved Oxygen Probe combines the power of multiple sensors to measure dissolved oxygen, water temperature, and atmospheric pressure. Ideal for experiments in biology, ecology, and environmental science courses, the probe uses luminescent technology to provide fast, easy, and accurate results. Perfect for field or laboratory, the waterproof probe requires no calibration, no filling solution, no warmup time, and no stirring—it is ready to sample dissolved oxygen immediately so more class time can be spent on the investigation.

Use the Go Direct® Optical Dissolved Oxygen Probe in a variety of experiments:

• Investigate the relationship between temperature and dissolved oxygen in water
• Measure primary productivity or biological/biochemical oxygen demand
• Explore the interdependence of plants and animals
• Monitor watersheds over time

Product Features
Rechargeable Battery—Ready When You Are
The robust rechargeable battery offers long battery life and provides always-ready operation when using the sensor wirelessly. Monitor battery life directly from the award-winning Vernier Graphical Analysis® Pro app, as well as LabQuest® 3. Should the battery run low, simply connect the sensor to the included charging cable and keep on collecting—no interruptions or inconvenience to you or your students.

Wireless or Wired—The Flexibility to Choose
The Go Direct® sensor connects directly to your mobile device and Chromebook™ or other computer using the Vernier Graphical Analysis® Pro app—no additional equipment or software purchases are necessary. The sensor also can be used wired via USB or wirelessly via Bluetooth® technology, allowing you to choose the solution best for your classroom or laboratory.
