Choosing a used analytical balance comes down to readability, condition, and what the listed price leaves in your equipment budget. These two used balances from Mettler Toledo and Ohaus sit on opposite sides of that trade-off. The Mettler Toledo MS105 NewClassic MF Semi-Micro Analytical Balance Scale 120g is listed at USD 789.00. The Ohaus Adventurer AR1530 Analytical Balance .001g Scale is listed at USD 363.95. That is a USD 425.05 difference in listed price, so the real question is how much the MS105's added resolution is worth to you.
Quick Verdict
If extra decimal places matter more than a pristine draft shield, the Mettler Toledo MS105 is the balance that offers them, but it is listed with a repair flag. If you want a used analytical balance described as working without that flag, the Ohaus Adventurer AR1530 is the simpler call.

Product Notes
Mettler Toledo MS105 NewClassic MF Semi-Micro Analytical Balance Scale 120g
The Mettler Toledo MS105 brings semi-micro capability to your bench with 0.01 mg readability in a 120 g balance. If your workflow needs that extra decimal place, this is the product that can deliver it. The limitation is impossible to miss: the listed unit is described as as-is / needs repair, with physical damage to the draft shield housing. The electronics and internal mechanics are said to function, so it may be a parts or repair project rather than a plug-and-play instrument. Because it is listed as used, that damage means you are evaluating a repair candidate. The NewClassic MF designation and Model MS105 identify the specific platform, so there is no ambiguity about which balance you are considering.
Ohaus Adventurer AR1530 Analytical Balance .001g Scale
The Ohaus Adventurer AR1530 is the straightforward option for routine analytical weighing. It is described as being in good working condition, and its listed attributes are clean: Model AR1530, MPN AR1530, no custom bundle, and no modifications. The limitation is resolution: at .001g it stops short of the 0.01 mg readability that the Mettler Toledo offers. If your methods require the kind of extra decimal places the MS105 can produce, the AR1530 will not get you there. For everyday work that stays at milligram-level readability, though, it is a much easier balance to say yes to.
Final Choice by Use Case
If your daily work needs the finer readability the MS105 can provide, the Mettler Toledo MS105 is the one to evaluate, with the repair project in mind. If you need a used analytical balance for routine weighing and want to avoid that project, the Ohaus Adventurer AR1530 is the cleaner choice.
