If you're comparing lab balances scales, the first decision is often analytical versus top-loading. Two used Mettler instruments show exactly that trade-off. The Mettler AE 100 Analytical Balance Laboratory Scale with Draft Shield and the Mettler Toledo PM4600 DeltaRange Lab Precision Balance Scale 4100g 0.01g are both used instruments, but they are built for different kinds of work. The AE 100 is an analytical balance with a draft shield, while the PM4600 is a top-loading precision balance with a 4100g capacity and 0.01g readability.
Quick verdict: Choose the AE 100 if you want a shielded analytical balance for physical laboratory work and you're willing to handle calibration. Choose the PM4600 DeltaRange if you need a top-loading balance with a large capacity and 0.01g readability for a broader range of lab disciplines.
At a glance:
| Feature | Mettler AE 100 | Mettler Toledo PM4600 DeltaRange |

Where each product wins:
- Mettler AE 100 wins for analytical weighing with a draft shield. It is the lower-priced balance and is specifically positioned for physical laboratory tasks.
- Mettler Toledo PM4600 DeltaRange wins for capacity and multi-discipline use. It offers a 4100g capacity with 0.01g readability, plus a stainless steel pan and data I/O interface.
Mettler AE 100 Analytical Balance Laboratory Scale with Draft Shield
This used Mettler AE 100 is an analytical balance with a draft shield, built for physical laboratory work. It is the more affordable option in this comparison, and the shield is a valuable inclusion for fine measurements where air currents can cause drift. The unit shows clear signs of use, including scuffs and blemishes, and it would need calibration before you can trust its readings; no calibration weights are included. If you are comfortable arranging calibration, the AE 100 gives you an analytical balance with the shield already attached. Its limitation is that it is not turnkey-ready, and the used condition means cosmetics are not perfect.
Mettler Toledo PM4600 DeltaRange Lab Precision Balance Scale 4100g 0.01g
The PM4600 DeltaRange is a Swiss-made, pre-owned top-loading balance with a 4100g capacity and 0.01g readability. Its DeltaRange design delivers a high-resolution weighing window, which is helpful when you need to measure small changes within a large sample. The balance is suited to laboratory, research, chemistry, biology, and pharmaceutical work, and it comes with a stainless steel weighing pan, integrated digital controls, a data I/O interface, and an AC power cord. The housing retains university asset markings from a previous lab, which may matter if you want pristine equipment. It also costs more than the AE 100, making it the pricier entry in this pairing.
Final choice by use case:
Choose the AE 100 if your priority is a shielded analytical balance for physical lab tasks, and you are willing to handle calibration. Choose the PM4600 DeltaRange if you need top-loading convenience with a large 4100g capacity, 0.01g readability, and multi-discipline versatility. For most labs that weigh a variety of sample sizes, the PM4600 is the more flexible instrument; for fine analytical work with a lower budget, the AE 100 is the sensible starting point.
