The decision
When your coffee setup is missing a measurement tool, it's hard to know whether your cold brew is coming out too weak or too strong. A coffee TDS meter answers that by showing how much dissolved coffee solid is in the brew, which makes it easier to repeat a batch that works. The tricky part is when the same used model shows up in two offers: the Cold Brew Avenue TDS PRO Digital Coffee Concentration Refractometer Tester, with one lower listed price and one higher listed price. Both offers carry the same title, used condition, digital power source, refractometer type, and coffee final-product attribute. So the decision comes down to price and the amount of context each offer gives you.
Quick verdict
If you want the same model name and the same used-condition digital refractometer, the USD 115.90 offer is the practical pick. It gets you the Cold Brew Avenue TDS PRO at the lower listed price. The USD 125.00 offer is worth a look only if you want the fuller original TDS-PRO write-up in the offer description, including the 1/100th reading capability and coffee/cold brew/tea use, and you're comfortable paying about $9.10 more for that page-level detail.

Where each listing wins
- Lower-priced offer wins on price. It offers the same model name, same used condition, and same digital refractometer specs for a lower listed price. Its description adds that the unit was used a few times and works perfectly.
- Higher-priced offer wins on included product context. It spells out the original Cold Brew Avenue TDS-PRO capabilities: readings to the 1/100th and the ability to measure coffee, cold brew, and tea. That's useful if you want to read the full feature explanation before you buy.
Product notes
Cold Brew Avenue TDS PRO (lower-priced listing)
This is the cheaper route to the same Coffee Concentration Refractometer model. The description says the unit has been used a few times and works perfectly, which is a clear condition note for a used digital meter. Since both offers share used condition, digital power, refractometer type, and coffee as the final product, the lower-priced offer's main advantage is the smaller outlay. The trade-off is that you don't get the longer TDS-PRO write-up with the mention of 1/100th readings or cold brew/coffee/tea use. If you already know the tool's range, that extra context won't matter much. If you want the full explanation without looking it up, you'd have to go with the higher-priced offer.
Cold Brew Avenue TDS PRO (higher-priced listing)
This offer costs more but brings the original description with it. The copy explains the pro-line meter's more precise reading to the 1/100th and says it's suitable for coffee, cold brew, and tea, giving you a fuller picture of what TDS-PRO can handle. That's the main reason to consider this one over the cheaper offer. The downside is straightforward: the listed price is higher and the condition is still used, so you're paying extra for the same model and the same used status. You're not getting a new meter, and the feature set described matches the same TDS-PRO naming. Pick this one if reading the full product explanation before you buy matters more than saving the price difference.
Final choice by use case
For most people, the lower-priced Cold Brew Avenue TDS PRO offer is the better buy. It gives you the same used digital refractometer, the same model name, and a straightforward condition note for less money. The higher-priced offer makes sense if you want the complete original TDS-PRO description to read before you commit. Once you have the meter, though, both offers point to the same measurement function, so the low-price route wins unless that offer copy is worth more to you.
