Yes. If you have an older edition of a Vernier lab book that only has procedures using the Dissolved Oxygen Probe (DO-BTA), you can access the most up-to-date version of the lab book through your online account. From there you can download the updated version that will have instructions for using the Vernier Optical DO Probe (ODO-BTA).

Instructions for using Go Direct® Optical Dissolved Oxygen Probe (GDX-ODO) are currently only available in the 4th edition Vernier lab books.
