When you're setting up or restocking a lab, the balance you choose depends on what you're weighing day to day. Some tasks need readings in milligrams; others just need a rugged scale for heavier items. Choosing the wrong one means either losing accuracy on small samples or ending up with a scale that can't handle the workload. That's the core choice between the Prime Scales PS-203 analytical balance and the Ohaus Scout SPX8200 portable precision balance.
Quick verdict: If your work demands high precision, the Prime Scales PS-203 is the better fit. If you need a replacement unit for an existing Scout setup, the Ohaus Scout SPX8200 is a practical choice.
The table below shows how their most important specifications differ.

| Type | Analytical balance | Portable precision balance |
| Listed price | $389.99 | $68.40 |
| Condition | New | New open box, without original packaging |

| Weighing pan | Included, stainless steel | Not included; needs existing components |
Where each product wins
The Prime Scales PS-203 is the go-to when your procedure calls for weighing small quantities with high accuracy, and you want a balance that's complete and ready to use out of the box. The Ohaus Scout SPX8200 is the better fit when you already have a Scout setup and simply need a new base unit to replace a damaged one, or when you have the pan and support already.
Prime Scales PS-203
The Prime Scales PS-203 is a new analytical balance with a 200 g capacity and 0.001 g readability, so it can weigh a single milligram of material with confidence. The glass draft shield is a standout feature because it keeps air currents from disturbing the reading, which is crucial when you're measuring very small quantities. The stainless steel weighing pan, tare and zero functions, multiple weighing units, and adjustable leveling feet mean the scale is ready for routine lab work without any extra purchases. The fast stabilization time also helps you move through repetitive weighings quickly. The main limitation is the 200 g capacity: if you need to weigh a batch of powder, a large beaker, or anything heavier, this unit won't handle it.
Ohaus Scout SPX8200
The Ohaus Scout SPX8200 is a new open-box portable precision balance listed at $68.40. The unit has never been placed into service, but the removable stainless steel weighing platform and top pan support are not included, so you'll need to supply those parts or use it to restore an existing SPX8200. It powers on and is intended for biological, dental, medical, microbiological, and physical laboratories, as well as industrial and educational use. The lack of original packaging is a minor concern, but the bigger issue is the missing pan. If you already have the pan and support, this is a very economical way to put a high-quality portable balance back to work.
Final choice by use case
Choose the Prime Scales PS-203 for analytical weighing tasks that demand high precision. Choose the Ohaus Scout SPX8200 if you already own the missing components and need a replacement balance for general lab or industrial work. If you're starting your lab from scratch and need to weigh accurately right away, the PS-203 gives you a complete setup. If you're repairing an existing SPX8200 or have parts lying around, the SPX8200 is the more practical route.
