Choosing lab balances scales comes down to a practical tradeoff: do you need fine 0.001g readability, a larger weighing capacity, or a replacement-oriented unit that fits equipment already on hand? The four options here range from USD 68.40 to USD 330, with meaningful differences in capacity, readability, condition, and included components.
Quick take
The A+D Electronic Precision Balance Scale Model FX300iN is the clear direction for work centered on 0.001g readability and a 320g capacity. For larger samples while retaining 0.01g readability, compare the Mettler Toledo PM4600 DeltaRange Lab Precision Balance Scale 4100g 0.01g and the Ohaus SPX2202 Precision Balance 2200g x 0.01g Tested Working Lab Scale. The Ohaus Scout SPX8200 Portable Precision Balance 8200g x 1g No Pan has the largest stated capacity, but its missing weighing platform and top pan support make it a specialized replacement or restoration choice rather than a complete setup.
Listed price comparison
| Balance | Listed price | Price position |
|---|---|---|
| Ohaus Scout SPX8200 8200g x 1g No Pan | USD 68.40 | |
| Mettler Toledo PM4600 4100g 0.01g | USD 185.00 | |

Decision matrix
- Prioritize the finest stated readability: Select the A+D FX300iN, listed with 0.001g readability and 320g capacity.
- Weigh larger quantities with 0.01g readability: The Mettler Toledo PM4600 pairs 4100g capacity with 0.01g readability.
- Need an Ohaus Scout balance at 2200g x 0.01g: The used SPX2202 is the direct match, with medical laboratory listed as its intended discipline.
- Already have Scout SPX8200 platform components: The open-box SPX8200 offers 8200g x 1g specifications, but the removable stainless-steel weighing platform and top pan support are missing.
- Prefer a top-loading balance designation: The PM4600 is identified as a top loading balance.
Product notes
Ohaus Scout SPX8200 Portable Precision Balance
The Ohaus Scout SPX8200 is the choice for a high stated capacity of 8200g when 1g readability suits the task. It is also the lowest-listed-price option at USD 68.40 and is described as new open box. Its portable precision-balance format is positioned for laboratory, industrial, educational, manufacturing, and quality-control applications. The central limitation is unusually important: it comes without the removable stainless-steel weighing platform and top pan support. That makes the SPX8200 most sensible for someone restoring an existing unit or already working with those Scout components, rather than for a setup that needs every weighing component included.
Ohaus SPX2202 Precision Balance 2200g x 0.01g
Choose the Ohaus SPX2202 when 0.01g readability and a 2200g capacity fit the intended sample range. This used Scout-series balance is described as tested working and has a digital LCD display; medical laboratory is listed as its intended discipline. At USD 206.15, it sits above the PM4600 in listed price while offering a lower stated capacity. The tradeoff is condition: the SPX2202 was previously used in a research laboratory environment. Its description also says the most recent calibration date is from late 2024 and that the calibration certification is no longer current, so it is best considered for buyers whose selection centers on the stated model, capacity, and readability.
Mettler Toledo PM4600 DeltaRange Lab Precision Balance Scale
The Mettler Toledo PM4600 makes the strongest case for weighing comparatively larger loads without stepping down from 0.01g readability: its title states 4100g and 0.01g. It is designated as a top loading balance and includes an AC power cord plus a data I/O interface in the description. The stated intended disciplines span laboratory, research, chemistry, biology, pharmaceutical, and industrial work, making its positioning broad. The limitation is that it is pre-owned, and university asset markings remain on the housing. At USD 185.00, the PM4600 is listed below the SPX2202 while offering the higher stated capacity of the two.
A+D Electronic Precision Balance Scale Model FX300iN
Pick the A+D Electronic Precision Balance Scale Model FX300iN when fine readability is the primary requirement. Its description states 0.001g readability, a 320g capacity, and a 1-second stabilization time; biological laboratory is listed as its intended discipline. The unit is described as new open box, assembled for a marketing video rather than placed into regular service. Its limitation is straightforward: the original box and directions are missing, and a company asset tag is attached to the bottom. With a listed price of USD 330, the FX300iN is the highest-priced balance in this comparison, reflecting a distinctly finer stated readability than the 0.01g and 1g alternatives.
Final recommendation by use case
For the finest stated measurement increment, choose the A+D FX300iN. For 0.01g work with the largest listed capacity among the two 0.01g choices, select the Mettler Toledo PM4600. Choose the Ohaus SPX2202 for its 2200g x 0.01g Scout configuration and medical-laboratory designation. The Ohaus Scout SPX8200 fits a narrower scenario: large-capacity 1g work where the missing pan and support are already accounted for.
