When you're looking at lab balances scales for a repair bench, the first decision is about weighing range versus readability. These two Mettler Toledo units sit at opposite ends of that trade-off: the MS105 is a semi-micro analytical balance built for small masses, while the MS4002TS/00 is a precision balance built for much larger loads. Neither is a plug-and-play working balance, so you are really choosing which repair path fits your lab.
Quick Verdict
Pick the MS105 if your samples are small and you need fine analytical readability, and if you are ready to handle a repair project. Pick the MS4002TS/00 if you work with much larger samples and can troubleshoot a startup failure. If you need a working balance immediately, neither unit should be your choice.
Side-by-Side Snapshot
| Model | Listed Price | Price Bar | Capacity | Condition |
|---|---|---|---|---|
| Mettler Toledo MS105 NewClassic MF Semi-Micro Analytical Balance | USD 789.00 | 120g with 0.01mg readability | Used; sold as-is, needs repair due to cracked draft shield | |
| METTLER TOLEDO MS4002TS/00 Precision Balance 4,200g | USD 199.95 | 4,200g precision balance | For parts or not working; powers on but does not load its application |
Where Each Product Wins
The MS105 wins when the job is semi-micro analytical weighing. This is the model with NewClassic MF semi-micro design, and while the housing is damaged, the electronics and internal mechanics function. If you can repair or replace the damaged housing, the scale's fine readability makes it a strong fit for small analytical samples.
The MS4002TS/00 wins when sample size is the priority. It handles far larger loads than the MS105. It is also intended for biological laboratory use, and the display and ports are in great shape. The main problem is functional rather than cosmetic, so the win depends on your willingness to diagnose that startup issue.
Product Notes
Mettler Toledo MS105 NewClassic MF Semi-Micro Analytical Balance Scale 120g
The MS105 is the finer-resolution candidate. It combines 120g capacity with 0.01mg readability, so it suits measuring very small masses in a lab setting. Its condition is Used, and the unit is sold as-is for repair because the draft shield housing has physical damage. The electronics and internal mechanics function, which narrows the repair work to the housing. That makes it a strong choice for someone who already has a replacement draft shield or can repair the existing one. The limitation is equally concrete: before any weighing can happen, the damaged housing has to be addressed.
METTLER TOLEDO MS4002TS/00 Precision Balance 4,200g
The MS4002TS/00 is the high-capacity project. It brings a 4,200g weighing range, which puts it in a different class from the 120g MS105. It is intended for biological laboratory use, and the cosmetic details are mostly known: a chipped rear foot tip and a cracked pan ring, while the display and ports are in great shape. The real obstacle is that the scale powers on but does not load its application, and the condition is for parts or not working. If your strength is diagnosing electronic startup issues, this balance gives you a large-capacity precision instrument to work on. If you are not equipped for that kind of troubleshooting, the balance won't become usable.
Final Choice by Use Case
- Choose the MS105 if you weigh small samples, need fine analytical readability, and can handle physical repair work.
- Choose the MS4002TS/00 if you weigh larger samples and can troubleshoot a startup failure.
- Skip both if you need a working lab balance right away; these are repair projects, not ready-to-run instruments.
