Choosing a lab balance often starts with a trade-off rather than a spec sheet. For lab balances scales, the two most common priorities are fine readability and practical capacity. You can have very fine readability or you can have more capacity for a lower price, and this head-to-head puts that choice in front of you with two Ohaus balances: the Adventurer AR1530 and the SPX2202. One is an analytical balance built for fine measurements; the other is a precision balance made for larger loads and routine lab work.
Quick verdict
Pick the Ohaus Adventurer AR1530 if fine analytical readability is the must-have. Pick the Ohaus SPX2202 if you want more capacity and a lower listed price; the price spread between the two is USD 157.80.
Comparison at a glance
| Product | Listed price | Readability | What stands out |
|---|---|---|---|
| Ohaus Adventurer AR1530 Analytical Balance .001g Scale | USD 363.95 | 0.001g | Analytical balance |
| Ohaus SPX2202 Precision Balance 2200g x 0.01g Tested Working Lab Scale | USD 206.15 | 0.01g | 2200g capacity, tested working |
Where each balance wins
The Adventurer AR1530 wins when the measurement needs the extra decimal place. Its strength is the finer readability of the two, and that is what the listing emphasizes.
The SPX2202 wins when you want to weigh larger samples and keep the budget in check. It is the less expensive unit here, and it is the one with the explicit tested working note in its listing.
Product notes
Ohaus Adventurer AR1530 Analytical Balance .001g Scale
The AR1530 earns its place when fine analytical readability matters in the lab. With 0.001g resolution, it is the more precise balance in this head-to-head, and the listing presents it as a used Ohaus unit in good working condition. It is listed at USD 363.95, the higher of the two prices. That price is the limitation: unless your protocol genuinely depends on three-decimal readings, the extra cost is hard to justify when the competing balance offers larger capacity for less. It is not about weighing speed or large loads; it is about resolution. If milligram-level measurements are part of your daily routine, the AR1530 is the balance to start with.
Ohaus SPX2202 Precision Balance 2200g x 0.01g Tested Working Lab Scale
The SPX2202 is the capacity-first choice in this pairing. Its 2200g load range gives it room for larger samples, while 0.01g readability covers general lab weighing. The listing says it is tested working and previously used in a research laboratory, which is useful context. At USD 206.15, it carries the lower listed price. The limitation is resolution: one-hundredth of a gram is not intended for milligram-level analytical work, so this is not the balance to choose when you need the finer readability of the AR1530. If your work stays within a larger capacity range, the SPX2202 is the more practical, lower-price option.
Final choice by use case
Choose the Ohaus Adventurer AR1530 when analytical readability and three-decimal resolution matter more than price. Choose the Ohaus SPX2202 when larger capacity and a lower listed price fit your routine, especially if the tested working note in its listing gives you confidence. The AR1530 is the precision-first pick; the SPX2202 is the capacity-first, lower-price pick.
