For LabQuest 2 and LabQuest 3
LabQuest Viewer® (LQ-VIEW), is computer software that makes it possible to view and control a LabQuest screen from a computer. This allows you to project the LabQuest screen using a computer that is set up to project.
A LabQuest Viewer app is also available for use with iPad. For more information, see https://www.vernier.com/product/labquest-viewer-for-ipad/
For original LabQuest
You can also project the LabQuest screen using the free LabQuest Emulator software. The emulator runs on PCs running XP, Vista, and Windows 7. It can also run on a Mac running XP, Vista, or Windows 7, but is not available in a native Mac OS X version. Do you offer a Mac-compatible LabQuest Emulator?
Download the emulator from https://www.vernier.com/downloads/labquest-emulator/
You can also project the original LabQuest Screen using the LabQuest Viewer software or iPad app. However, the original LabQuest requires an external Wi-Fi radio that is no longer sold by Vernier.
