Choosing a lab balance scale usually comes down to two questions before you put anything on the pan: how much sample can the balance hold, and how finely can it measure? The four Mettler Toledo and Ohaus balances here cover listed prices from USD 68.40 to USD 1,999.00, with readability from 1 g down to 0.01 g. Some are top-loading, one is portable, and one is an open-box unit without its weighing pan. That range is why the practical first step is defining your weighing job, then matching the listed price and included hardware to it.
Quick take
If automatic internal calibration is important, the Mettler Toledo XSR1202S is the balance to plan around. If you want a large-pan balance with 0.01 g readability and a stainless steel weighing pan, the Mettler Toledo PM4600 is the high-capacity 0.01 g option here. If you already have an Ohaus Scout SPX8200 and need a replacement main unit, the NEW OPEN BOX Ohaus Scout SPX8200 fills that role at the lowest listed price in this set. If you want a middle-ground option described as tested working, the Ohaus SPX2202 is the one to weigh.

Decision matrix
| If you need | Consider | Why |
|---|---|---|
| Automatic internal calibration and a compact top-loading balance | Mettler Toledo XSR1202S | Used unit with FACT automatic internal calibration, described as professionally inspected and tested |
| A high-capacity balance with 0.01 g readability and a stainless steel pan | Mettler Toledo PM4600 | Swiss-made top-loading balance with data I/O interface and AC power cord |
| A portable replacement unit at the lowest listed price in this set | NEW OPEN BOX Ohaus Scout SPX8200 | Powers on and has never been used, but the pan and top pan support are not included |
| A tested working middle-capacity precision balance | Ohaus SPX2202 | Maintained on an annual calibration schedule during its previous lab service |
Mettler Toledo XSR1202S Precision Balance (1210 g / 0.01 g
This used Mettler Toledo XSR1202S brings FACT automatic internal calibration to a top-loading platform with 1,210 g capacity and 0.01 g readability. The unit is described as professionally inspected, cleaned, and fully tested, and the XSR Excellence Series is one of Mettler Toledo's premier laboratory balance platforms. It is a natural choice if you work in pharmaceutical, biotechnology, research, quality control, or industrial lab settings and you want the calibration handled automatically. The limitation is the scale of the capacity: at 1,210 g it is the smallest capacity in this comparison, and the balance is used rather than new or open box.
Mettler Toledo PM4600 DeltaRange Lab Precision Balance Scale 4100g 0.01g
The Mettler Toledo PM4600 is a used top-loading balance with the largest capacity among the 0.01 g options at 4,100 g. It is described as Swiss-made with a stainless steel weighing pan, integrated digital controls, a data I/O interface, and an AC power cord. That makes it a complete weighing setup as described, not a bare main unit. Its main limitation is cosmetic condition: it was removed from a university laboratory and still carries the university's asset markings on the housing.
NEW OPEN BOX Ohaus Scout SPX8200 Portable Precision Balance 8200g x 1g No Pan
The Ohaus Scout SPX8200 is a new open-box portable precision balance with the largest capacity in the group at 8,200 g and 1 g readability. It has never been placed into service. The balance powers on, but the original factory packaging is not included, and the removable stainless steel weighing platform and top pan support are missing. That makes it most attractive if you already own those parts for an existing Scout SPX8200 or are restoring one. The key limitation is that it is not a ready-to-weigh instrument from the box; you still need the pan and pan support before normal weighing.
Ohaus SPX2202 Precision Balance 2200g x 0.01g Tested Working Lab Scale
The Ohaus SPX2202 is a used precision balance with 2,200 g capacity and 0.01 g readability. It was previously in a research laboratory and maintained on an annual calibration schedule during service. The unit is described as remaining in excellent working condition and tested for functionality, and it includes a digital LCD display. Its capacity gives it a middle-ground position between the smaller XSR1202S and the larger PM4600 and Scout. The limitation is calibration status: the balance was removed during its final calibration cycle, so the most recent calibration certificate is no longer current because the balance is out of service. The description attributes that to service status rather than an operational issue.
Final recommendation by use case
For a compact top-loading balance with automatic internal calibration, the Mettler Toledo XSR1202S at USD 1,999.00 is the direct choice. For a high-capacity 0.01 g balance with a stainless steel pan and AC power cord, the Mettler Toledo PM4600 at USD 185.00 delivers the most headroom among the 0.01 g balances here. For a portable replacement main unit, the NEW OPEN BOX Ohaus Scout SPX8200 at USD 68.40 works only if you can supply the missing pan and top pan support. For a tested working 0.01 g balance, the Ohaus SPX2202 at USD 206.15 is the balanced middle option.
