Choosing between the Mettler Toledo PM4600 DeltaRange and the Mettler Toledo XSR1202S comes down to a classic trade-off: how much capacity you need and how much you are paying for it. Both are top-loading balances from the same manufacturer, and both show 0.01 g readability in their product names. But the PM4600 offers 4100 g of capacity at a listed price of USD 185.00, while the XSR1202S lists at USD 1,999.00 and gives you 1210 g of capacity. The stated price difference of USD 1,814 makes this a matter of matching the balance to the work you actually do.
Quick Verdict
If your work involves larger sample weights and a lower listed price is important, the PM4600 DeltaRange is the balance to choose. If you value automatic internal calibration and the Excellence Series platform more, and your samples stay within 1210 g, the XSR1202S justifies its higher listed price.

The XSR1202S wins on automatic calibration and platform design. FACT automatic internal calibration makes calibration hands-off, and the Excellence Series platform is designed for pharmaceutical, biotech, research, quality control, and industrial laboratories. This unit has been professionally inspected, thoroughly cleaned, and fully tested.
Product Notes
Mettler Toledo PM4600 DeltaRange Lab Precision Balance Scale 4100g 0.01g
The PM4600 is a used top-loading balance offering 4100 g capacity and 0.01 g readability. Its DeltaRange feature keeps high-resolution weighing available across the capacity, making it useful for mixed sample sizes. The unit includes an AC power cord and a data I/O interface, and it has a stainless steel weighing pan. The housing still carries UC Berkeley asset markings from its previous university lab use. If your priority is a wide weighing range and the lower of the two listed prices, this is the more practical choice.
Mettler Toledo XSR1202S Precision Balance (1210 g / 0.01 g
The XSR1202S is a used top-loading balance with 1210 g capacity and 0.01 g readability. Its FACT automatic internal calibration is a defining listed feature, taking calibration out of your hands. The unit has been professionally inspected, thoroughly cleaned, and fully tested, and it belongs to the Excellence Series platform for pharmaceutical, biotech, research, quality control, and industrial labs. At USD 1,999.00, it is the higher-priced option, yet it delivers a specific combination of automatic calibration and a dedicated balance platform for labs that work within the 1210 g limit.
Final Choice by Use Case
Pick the PM4600 DeltaRange if you need the wider capacity and prefer the lower listed price. Pick the XSR1202S if automatic calibration, the Excellence Series platform, and a fully inspected unit matter more, and if 1210 g is enough for your samples. Both balances bring Mettler Toledo build and 0.01 g readability to the table, so the deciding factor is which feature set your lab values more.
