Choosing between the METTLER TOLEDO MS4002TS/00 and the Ohaus SPX2202 for your lab balances scales setup comes down to one hard question: do you need a scale that works today, or are you troubleshooting a current MS4002TS/00? The answer determines which of these two precision balances is the right buy.
Quick Verdict
If you need a functioning precision balance, the Ohaus SPX2202 is the clear choice at USD 206.15. It is sold as a tested working unit previously used in a research lab. The METTLER TOLEDO MS4002TS/00 costs USD 199.95, but it powers on without loading its application and is sold for parts or not working. Choose the METTLER only as a parts donor or repair project.

| METTLER TOLEDO MS4002TS/00 Precision Balance 4,200g \| P&R | USD 199.95 | For parts or not working | 4,200g capacity | Biological Laboratory | Parts donor or repair project |
| Ohaus SPX2202 Precision Balance 2200g x 0.01g Tested Working Lab Scale | USD 206.15 | Used, tested working | 2200g capacity, 0.01g readability | Medical Laboratory | Working lab scale |
Where Each Product Wins
Choose the Ohaus for any scenario where you want to start weighing samples immediately. It has a tested working function and a service history of regular annual calibration while in a research lab. That makes it the dependable pick for daily lab work.
Choose the METTLER TOLEDO if you already own an MS4002TS/00 and need a donor for the rear static footing, the plastic weigh pan ring, or other mechanical parts. The display and all ports and jacks are in good shape, but the unit powers on without loading its application, so it is not a working balance. Treat it as a repair project, not a measuring tool.
Product Notes
#### METTLER TOLEDO MS4002TS/00 Precision Balance 4,200g | P&R
The METTLER TOLEDO MS4002TS/00 is a precision balance intended for biological laboratory use, but this particular unit is in poor cosmetic and functional condition. The rear static footing has a chipped tip, and the plastic ring around the weigh pan is cracked through on one corner. The display and all ports and jacks are in good shape, which could matter if you are troubleshooting. However, the scale powers on without loading its application, and it is sold for parts or not working. That makes it a credible donor for an existing MS4002TS/00 or a repair project for someone who can source the faulty electronics. It should not be chosen for routine weighing, since there is no confirmed working function.
#### Ohaus SPX2202 Precision Balance 2200g x 0.01g Tested Working Lab Scale
The Ohaus SPX2202 is a tested working precision balance from the Scout series, previously used in a research laboratory and kept on an annual calibration schedule throughout its service life. It has a digital LCD display and has been tested for functionality. The balance was removed from service during the lab's final calibration cycle, so the calibration date from late 2024 is no longer current as a certificate. That lack of a current certificate is tied to the unit being out of service, not to a known operational issue. For a medical laboratory or anyone who needs to weigh immediately, the tested working function is the meaningful advantage. The main limitation is that the calibration certificate is not current, so it will not satisfy a laboratory procedure that requires a current certificate.
Final Choice by Use Case
If you need a working lab balance right away, the Ohaus SPX2202 is the practical pick. If you are repairing an MS4002TS/00 and need spare parts, the METTLER TOLEDO MS4002TS/00 becomes worth considering despite being non-functional. The decision should be driven by whether you need a functioning instrument or a donor unit.
