Look for the AquaScan through Dr. Jackson's water-equipment stock after unlocking Water Trading, or through the Retired Farmer's equipment offerings. A Service Department Supply Crate can also contain one, but that is a chance-based route. The scanner's listed base value is 200 Credits; the price of a particular transaction can differ from that reference value.
Once you have it, use it on the water container to read the actual grade, purity and contaminant breakdown. The label is only the declared grade. An AquaScan is especially useful when the water has stopped improving, because it shows which type of contamination still needs treatment rather than leaving you to guess from the grade name.
Check equipment stock after Water Trading
Water Trading is unlocked through Wild's Network. Its starter kit gives you the manual, testing strips, tablets, a pitcher, a filter, a sign and a used handheld purifier. The AquaScan is not one of those listed starter-kit items.
That distinction explains a common acquisition problem: purchasing the trade unlock and expecting the scanner to be among the kit's contents. The unlock expands access to equipment, but you still need to obtain the scanner itself from a source that has it.
Dr. Jackson begins stocking water equipment after the relevant unlock. That stock includes the AquaScan alongside other water-related machines and containers. Check the item name in his current offerings rather than buying another device merely because it looks like a scanner.
Do not confuse the AquaScan with a Gene Scanner or a plant-analysis tool. Those belong to other inspection tasks. A shop can own several handheld devices without having the tool that reads water contamination.
When budgeting the purchase, use the actual offer on screen. The 200-Credit base value is a reference for the item, not a promise that every seller and every situation uses exactly that price. Keep enough money for the water stock and treatments you intend to use alongside the new tool.
Check the Retired Farmer as another equipment route
The Retired Farmer's stock includes an AquaScan among farming equipment. Water analysis is relevant to more than a dedicated Water Merchant opening, so this is another named route to watch when planning your equipment purchases.
Keep that route separate from the Retired Water Merchant's ordinary listed inventory. The latter is a useful supplier for water gear such as filters, pitchers, tanks and the Water Purifier, but similar customer titles do not mean every seller carries the same device.
The practical task is to inspect the current stock for the exact AquaScan name. Do not replace the missing tool with a Water Testing Kit simply because both participate in testing. Strips are a useful fallback, but their information and consumable handling are different.
If the scanner is not currently available, continue using the testing method you have rather than assuming the whole water trade must stop. You can make cautious purchasing and labeling decisions with strips while waiting for the detailed device. What you should avoid is buying unknown water on the assumption that its label must be accurate.
Treat a Service Department crate as an opportunity
A Service Department Supply Crate has an AquaScan among its possible contents, with a listed 15% base roll. The same crate can contain other useful water items, including testing strips, filters and a UV Lamp. These are rolled entries, not a guaranteed bundle.
Open the crate with a disposable Service keycard, or a Command keycard that can open any department's crate. The keycard is consumed. Include both the crate and keycard in the cost of choosing this route.
A crate is useful to check if you already have one, but it should not be described as a fixed-price AquaScan purchase. You can open a valid crate and receive no scanner. Repeating the process does not create a guarantee that the next crate contains the missing item.
Luck affects crate-content chances, but that still does not let you select the scanner directly. Use any active Luck benefit as part of the crate system you are already using, rather than assuming it converts a chance-based acquisition into a certain one.
Use a testing strip while the scanner is missing
The Water Testing Kit holds individual strips. Take an unused strip from the kit and apply that strip to the water container. The jar or box holding the strips is the supply container; it is not the whole tool you apply to the bottle.
A used strip is consumed, so keep track of how many remain. Reusing the same spent strip on another batch is not a supported substitute for obtaining another unused one.
The strip provides the basic quality check needed to compare a declaration with the water itself. It does not purify the water. If the result is below the grade you need, the next task is treatment or a different purchase decision.
Use this fallback to keep the acquisition problem separate from the trading decision. Not owning the AquaScan yet is a reason to be more careful about unknown stock, not a reason to assume every container must be accepted without inspection.
Apply the AquaScan to the container you are evaluating
Once the device is available, select the actual container whose contents matter. If the counter holds several bottles, finish one inspection before moving them around. This prevents confusing one reading with another batch.
The useful information includes the tested grade, purity percentage, declared label and contamination. Read them together. The grade tells you the category the liquid currently reaches; the breakdown explains what may be preventing the next improvement.
A straightforward use sequence is:
- Identify the source container and keep it accessible.
- Apply the AquaScan to that container.
- Read the actual grade and purity before comparing the label.
- Inspect the contamination categories when planning treatment.
- Test again after the contents change.
- Label the finished container according to the new result.
The scanner measures the contents; it does not make them cleaner. You still need the appropriate treatment for the contaminant or the intended grade.
Separate the four pieces of information
| Reading | What it answers | What it does not establish |
|---|---|---|
| Declared label | What the container claims to contain | The actual purity of the liquid |
| Tested grade | Which water category the measured contents reach | Which treatment is needed next |
| Purity percentage | How clean the current mixture measures overall | Whether every contaminant responds to one tool |
| Contaminant breakdown | What remains in the mixture | That the batch has already been treated |
This separation is useful when a seller's description looks plausible. Ghostwater can resemble cleaner water, and a container's appearance is a poor replacement for a measurement. Read the real contents before making a purchase based on the higher-grade label.
Take an unused individual strip from the kit when testing without the scanner.
If the tested grade and the declaration disagree, use the game's challenge interaction for that actual discrepancy when negotiating. Do not treat the existence of a scanner as a reason to accuse every seller regardless of the result.
Retest after treatment, transfer or mixing
A previous scan describes the contents at the time of that scan. UV treatment, filtering, tablets, powered purification or blending can change those contents. Test the result instead of treating the initial measurement as permanently attached to the container.
This matters particularly when moving water through a pitcher. The source bottle and the receiving container can hold different water at different stages of the process. Inspect the destination that you plan to sell, not just the bottle that originally supplied it.
Mixing two batches also changes the combined composition. Cleaner water can improve a lower-purity batch, but the result depends on the actual quantities and purities. Scan after the transfer rather than assuming a small addition must have crossed a grade threshold.
Keep finished water separate once it has passed the final check. If you later add dirtier water, perform another test. A previously correct label can become inaccurate because the contents changed, even though the scanner never failed.
Use contamination readings to avoid the wrong purchase
The AquaScan is valuable because water treatments do different jobs. A UV Lamp targets microorganisms, while a pitcher filter handles suitable physical impurities. Heavy metals and chemical contamination can require a different treatment plan.
When a batch stops improving, inspect what remains before buying another copy of the same tool. A new filter will not automatically solve a contamination type the previous filter was never intended to address. A working UV Lamp is similarly not proof that every remaining substance should disappear.
For an overnight Water Purifier, compare the water's actual result with the machine's current purity ceiling and progress information. The scanner describes the water; the machine interface describes what the equipment can do. Both are needed to distinguish a finished process from an inadequate configuration.
This page does not require you to turn every measured batch into Pure Water. Choose the required use, then use the readings to decide the next treatment. A lower grade that suits a planned buyer or recipe can be a completed product for that purpose.
Check the sale label after the final scan
A container can retain an older label after the water improves. That creates the opposite problem from a dishonest seller: the contents may be better than the declaration. Use the label-matching interaction when the measured result is ready.
Changing a label does not alter purity. It only makes the declaration agree with the contents. If the real water is still below the buyer's requirement, relabeling it as that requested grade does not complete the treatment.
The acquisition goal is therefore only the first half of the workflow. Find the named scanner through equipment stock or a possible crate, apply it to the correct container, read the result, and repeat the check whenever the contents change. That turns the device into a useful decision tool rather than another object sitting unused among your water supplies.
