H2OPal can be fitted on several different water bottle that have a 3" diameter at the base. The other requirement to ensure reliable measurements is that the bottles by themselves should weight at least 2.8 oz or 80g when empty.
If you decide to use the H2OPal tracker with a different bottle you will also need to recalibrate the tracker using the H2OPal app.
To install the H2OPal tracker on the different bottle follow these steps:
1. Separate the tracker at the point of its magnetic connection from the bottle attachment.
2. Remove the bottle attachment from the H2OPal bottle.
3. Fit the bottle attachment to the new bottle.
4. Align the tracker with the bottle attachment to connect it onto the new bottle.
You can recalibrate the tracker in the H2OPal app by going to "H2OPal Tracker"->"Advanced Settings"-> scroll down to "CALIBRATE" -> and then follow the three step process.
More information about recalibration can be found in this help center article:
