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 Go Direct Optical Dissolved Oxygen Probe uses luminescent technology to provide fast, easy, and accurate results. Perfect for the field or for the laboratory, this probe requires no calibration, no filling solution, no warm-up time, and no stirring. This waterproof probe is ready to sample dissolved oxygen immediately without additional setup or the need to warm it up.
Wirelessly connect most Go Direct sensors to the Graphical Analysis Pro app in just seconds and collect, visualize, and interact with data in real time, from anywhere and on multiple devices
- Live data sharing during demonstrations. Great for in-person and remote learning
- Graph types, including bar graphs, histograms, and FFTs, plus the ability to plot categorical data
- Video-sensor data sync to replay, speed up, slow down, and pause recorded experiments at key moments in time
- Library of over 45 sample experiments ready to be analyzed by students as prep work, homework, or a makeup assignment
- User-defined curve fits, which allow advanced and more meaningful data analysis
Rechargeable Battery
The robust rechargeable battery offers long battery life and provides always-ready operation when using the sensor wirelessly. Monitor battery life directly from the Vernier Graphical Analysis™ Pro app, as well as LabQuest®3. Should the battery run low, simply connect the sensor to the charging cable and keep on collecting - no interruptions or inconvenience to you or your students.
Wireless or Wired
Go Direct sensors connect directly to your mobile device, Chromebook™, or computer using the Vernier Graphical Analysis™ Pro app - no additional equipment or software purchases are necessary. Go Direct sensors can be used wired via USB or wirelessly via Bluetooth® wireless technology, allowing you to choose the solution best for your classroom or laboratory.
