The OHAUS Scout SKX has been the daily balance on my workbench for six months, replacing a generic 0.1g kitchen scale that I had outgrown. I bought it at retail. OHAUS did not provide a sample. The Scout line has been around since the 1990s, and the SKX revision keeps the things that made it the default classroom and small-lab balance for a generation, while adding a backlit display and an updated housing. It is not the prettiest balance you can buy, and the display is a basic segment LCD. What it is, is reliable.
Why you should trust this review
I have used balances from OHAUS, Mettler, A&D, and Sartorius across years of laboratory and small-batch chemistry work, and I currently keep an analytical balance and a top-pan balance on my bench. The Scout SKX was purchased at retail. I tracked specific things over six months, including linearity at multiple loads, drift over 30-minute sessions, calibration retention, and how the unit handled airflow without a draft shield.
How we tested the OHAUS Scout SKX
- Verified linearity at 5g, 50g, 100g, and 200g using class F1 calibration weights.
- Logged display reading every 30 seconds for 30 minutes after stable load to measure drift.
- Performed external calibration with a 200g class F1 weight and rechecked after 30 days.
- Compared response time and stability against an A&D EJ-410 reference balance.
- Tested airflow sensitivity by running a small fan three feet from the pan and noting reading change.

Who should buy the Scout SKX?
Buy it if:
- You run a small chemistry, biology, or pharmacy lab and need 0.01g resolution at a working price.
- You want a balance that lasts a decade in classroom or shared-use environments.
- You weigh reagents, brewing salts, or supplements and need real accuracy, not kitchen-scale guess work.
Skip it if:
- You need 0.0001g resolution. The SKX is a top-pan balance, not an analytical balance.
- You measure samples above 220g routinely. The SKX222 capacity is 220g. Larger capacity SKX models exist.
- You only weigh occasionally and to the nearest gram. A $25 kitchen scale is enough.
Accuracy and stability: where the Scout earns the name
Across linearity tests with class F1 weights, the Scout SKX held within +/- 0.02g across the full 220g range, which is in line with the spec. Drift over a 30-minute session sat at the readability limit, meaning the displayed value moved a digit or two without a real load change but did not creep in one direction. That is what you want from a top-pan balance at this price.
Calibration: external, simple, and persistent
External calibration uses a single 200g class F1 weight. The procedure takes under a minute: hold CAL, follow the prompts, place and remove the weight, done. After calibration, the balance held within spec for 30 days of daily use without recalibration. Note that calibration weights are not included and a quality 200g class F1 weight runs $40 to $80, which is worth budgeting from day one.
Build and pan: the parts that survive a working lab
The stainless pan removes for cleaning by lifting straight up and the housing wipes down with isopropyl alcohol without any apparent finish damage. The buttons are rubberized and have held up to six months of typical lab use without sticking. The base is heavy enough to stay planted while you tare and load samples.
Display and modes
The backlit segment LCD is the part that looks dated next to a touchscreen Mettler. It is clear and readable from across a small lab, and it switches between weighing, parts counting, percent weighing, and totalization with a button press. The keyboard layout takes a session to get used to, but for daily weighing you mostly use the tare and zero buttons.
What it does not include
A draft shield is not in the box. At 0.01g readability, normal lab airflow will move the last digit. If your bench is near a vent or door, plan to add a draft shield or move the balance. Calibration weights are also separate. And the AC adapter cord is short, around three feet, which sometimes forces an extension cord on a crowded bench.
Where the Scout fits
The OHAUS Scout SKX is the right balance for a lab that has outgrown kitchen scales but does not need analytical resolution. It is accurate within spec, durable enough for shared use, and backed by a service network that has been around for decades. For the work it is designed to do, it is hard to beat at this price.

Should you buy the OHAUS Scout SKX Series Portable Lab Balance?
The OHAUS Scout SKX is the balance that small labs, schools, and serious hobbyists buy when a kitchen scale is not enough and a research-grade analytical balance is too much. The 0.01g resolution is honest, the stainless steel pan and ABS housing handle daily abuse, and the calibration via external weights is straightforward. It is not as pretty as a smart-display Mettler, but it weighs accurately, drifts very little, and lasts.
Frequently asked questions
Is the OHAUS Scout SKX worth $380 in 2026?+
For small labs, schools, or serious hobbyists, yes. The accuracy and reliability gap between this and a $25 kitchen scale is huge. For a 0.0001g analytical balance you need to step up to a Mettler or Sartorius.
OHAUS Scout SKX vs A&D EJ-410: which is better?+
The A&D is cheaper and offers higher capacity at the same readability. The OHAUS has a sturdier housing, a removable stainless pan, and a stronger US warranty network. For a fixed lab the OHAUS is the safer pick.
How accurate is the 0.01g readability claim?+
Verified within +/- 0.02g linearity using class F1 calibration weights. Drift over 30 minutes was at the readability limit. Air movement is the bigger source of variance, not the load cell.
Should I upgrade from a $25 kitchen scale to the SKX?+
If you weigh out reagents, brewing salts, or supplements at the gram level, yes. Kitchen scales drift, miscalibrate, and round aggressively. The SKX is in a different class.
