Stock and availability depend on your run.

Inspect a container#

  1. Use an owned AquaScan on a nonempty liquid container, including one offered by a trading partner.
  2. Compare actual purity with the label. Look at components when choosing a treatment.
  3. Scan again after changing the contents.

Readings and labels#

Scanning does not automatically relabel the water. An empty container has no test readout. Pouring or purification can clear a stored scan, so a previous result is not a substitute for inspecting the current batch.

Use the reading in a mixture#

Enter each measured volume and purity in the Water calculator. Use direct mixing only when the transfer does not filter or react. Check free space and measure the result again near a grade boundary.
