Shopping for a used lab balance means juggling two priorities: having enough capacity and getting a unit you can trust. Right now, two precision lab balances are competing for the same bench space: the Mettler Toledo PM4600 DeltaRange and the Ohaus SPX2202. Both are used precision lab balances from laboratory environments. The listed prices are close, at USD 185.00 for the Mettler Toledo and USD 206.15 for the Ohaus-about $21 apart-so the meaningful differences are capacity, provenance, and the working-condition claim in each product name.
Quick verdict
Pick the Mettler Toledo PM4600 if you want a higher-capacity balance. Its capacity is nearly double the Ohaus's range, and DeltaRange weighing is part of the product name. Pick the Ohaus SPX2202 if you prefer a unit whose title carries a tested-working claim.
Comparison at a glance
| Product | Listed price | Price bar | Capacity / readability | Condition |
|---|---|---|---|---|
| Mettler Toledo PM4600 DeltaRange Lab Precision Balance Scale | USD 185.00 | 4100g x 0.01g | Used | |
| Ohaus SPX2202 Precision Balance | USD 206.15 | 2200g x 0.01g | Used |
Where each wins
The Mettler Toledo PM4600 wins on capacity. Its maximum weight is well above the Ohaus's, so it can handle larger samples. Its intended-use scope spans laboratory, research, chemistry, biology, pharmaceutical, and industrial work. The Ohaus SPX2202 wins on stated working condition. Its intended use is medical laboratory work, and its service story includes annual calibration with the most recent date in late 2024.
Product notes
Mettler Toledo PM4600 DeltaRange
The main draw is capacity: 4100g at 0.01g readability, which is roughly double the Ohaus's maximum. The DeltaRange label appears in the title, and the balance was used in a university laboratory, with U.C. Berkeley asset markings remaining on the housing. It is Swiss-made and comes with an AC power cord. The condition is used, so the exterior may show signs of previous lab use. The unit is sold with the exact condition shown, so the visible state is part of the decision. If your samples are larger and you want maximum capacity, this is the direction to lean.
Ohaus SPX2202
The Ohaus brings a different emphasis: the title states "Tested Working." This unit served in a research laboratory, was maintained on an annual calibration schedule, and had its most recent calibration in late 2024. The calibration certification is no longer current because the balance was removed from service, so the late-2024 date is service history rather than active certification. That label is not a current certification but does reflect the unit's last known service state. The trade-off is capacity: 2200g maximum, roughly half of the Mettler Toledo. If your weighing stays under that cap and you want the explicit tested-working reassurance, this is the one to pick.
Final choice by use case
Choose the Mettler Toledo PM4600 when your samples and tare containers demand more capacity than the Ohaus offers and you want the widest possible range at the listed price. Choose the Ohaus SPX2202 when a smaller capacity covers your routine loads and you want a unit whose working condition is explicitly stated, with a maintenance history that runs to its final service cycle. Before you decide, think about the heaviest container-and-sample combination you normally place on the pan. If those loads stay comfortably within the Ohaus's range, the working-condition claim may matter more. If they approach or exceed that range, the Mettler Toledo's extra capacity is the stronger draw.
