Choosing a lab balance usually comes down to capacity versus readability. The METTLER TOLEDO MS4002TS/00 Precision Balance offers a wide weighing range, while the Ohaus Adventurer AR1530 Analytical Balance reads to the milligram. But the more immediate fork in this head-to-head is condition: one is sold as a parts unit, the other as a used balance. Here's what that difference means for anyone shopping for lab balances scales.
Quick verdict
If you need a large-capacity balance for the lowest possible price and you're comfortable troubleshooting non-functional equipment, the METTLER TOLEDO MS4002TS/00 is the budget pick. If you need small-sample accuracy now, the Ohaus Adventurer AR1530 is the more practical choice. The $164 gap between them is essentially the price of moving from a repair project to a ready-to-use analytical balance.
Comparison table
| Product | Price | Condition | Key Spec |
|---|---|---|---|
| METTLER TOLEDO MS4002TS/00 Precision Balance 4,200g | P&R | $199.95 | For parts or not working | 4,200 g capacity |
| Ohaus Adventurer AR1530 Analytical Balance .001g Scale | $363.95 | Used | 0.001 g readability |
Where each product wins
The Mettler wins on price and capacity. It's the lower-cost entry into a precision balance with a 4,200 g range. That big capacity is valuable in a biological lab context when you're weighing larger samples. The catch is that this unit has been tested and is non-functional: it powers on but doesn't load its application. There is also cosmetic damage, including a chipped static footing and a cracked weigh-pan ring.
The Ohaus wins on readability and readiness. For a higher price, you get a used analytical balance with high resolution, which is essential for small sample weights. It's a used unit, but it's described as being in good working condition, so it's the one you can put on the bench without a repair project.
Product notes
#### METTLER TOLEDO MS4002TS/00 Precision Balance
The METTLER TOLEDO MS4002TS/00 Precision Balance is your option if you want to stretch dollars toward capacity. It is priced at $199.95, which makes it the least expensive of the two units, and it carries the MS4002TS/00 model designation as a precision balance. The reason to pick it is the 4,200 gram range: that's a lot of weighing surface for the money. The limitation is that it is sold for parts or not working. It powers on but does not load its application, and there's visible damage to the rear static footing and the plastic ring around the weigh pan. If you have a repair background or need donor components for another Mettler Toledo, this is a low-cost source. If you need to weigh a sample today, you'll need another balance while you work on this one.
#### Ohaus Adventurer AR1530 Analytical Balance
The Ohaus Adventurer AR1530 Analytical Balance is the more expensive option at $363.95, and for that price you get 0.001 g readability. That level of resolution makes it suitable for weighing small samples in a biological lab. The reason to choose it is that it is a used balance in good working condition, so you avoid the troubleshooting step. It is not a custom bundle and is not a modified item. The trade-off is price: it costs more than the Mettler, and it's still a used instrument rather than a new one. If your work depends on precise, small-sample measurements and you can absorb the higher cost, this is the balance that can get to work sooner.
Final choice by use case
The final call is straightforward. Choose the METTLER TOLEDO MS4002TS/00 when your priority is a large precision balance and you're willing to spend time and money on repairs. It's the low-cost path to that kind of capacity. Choose the Ohaus Adventurer AR1530 when your priority is precise small-sample measurements and a balance you can use now. The extra cost gets you a used analytical balance that is ready for the bench. For a lab that weighs small samples and needs results immediately, the Ohaus is the right purchase. For a repair bench that needs a high-capacity donor, the Mettler makes sense.
