2 ntep legal for trade vs non-ntep scales explained
NTEP stands for the National Type Evaluation Program.
It’s a rigorous testing and certification process that ensures a scale meets government standards for accuracy and reliability set by the National Conference on Weights and Measures (NCWM).
A scale that is NTEP approved is certified as “Legal for Trade,” meaning you can legally use it in any commercial transaction where price is determined by weight.
3 when do you need an ntep certified scale
If you are buying or selling anything based on its weight, you must use an NTEP certified scale.
Common applications include shipping carriers, recycling centers, retail bulk sales, and manufacturing processes where payment is weight-based.
For internal processes—like inventory checks or batching ingredients—you can use a non-NTEP scale.
4 key features of an industrial bench scale
Beyond certification, several core features determine if a 500 lb. bench scale is right for your environment and tasks.
A quality industrial bench scale is more than a platform; it’s a system designed for durability and precision.
Pay close attention to capacity, readability, construction material, and power options.
5 capacity vs readability 500 lb x 0.1 lb
You’ll often see “500 lb x 0.1 lb.”
Capacity (500 lb) is the maximum weight the scale can measure, while readability (0.1 lb) is the smallest increment displayed.
Match readability to your needs—0.1 lb suits general shipping, whereas 0.05 lb is better for counting small parts.
6 construction material stainless steel vs carbon steel
Material impacts durability and suitable environments.
Stainless steel resists corrosion and is ideal for washdown or food-processing settings.
Painted carbon steel is economical and durable for dry warehouse floors.
7 power options ac adapter and rechargeable battery
Most bench scales offer dual power.
An AC adapter lets you plug into a wall outlet for continuous use.
A built-in rechargeable battery provides mobility, perfect for inventory in large facilities.

12 how to calibrate your bench scale
Calibration keeps your scale honest.
Set the scale on a level, stable surface and let it warm up.
Enter calibration mode per your manual.
Place a certified weight (at least 50% of capacity) on the platform, confirm, and save.
Monthly calibration is ideal for heavy use; quarterly suffices for lighter workloads.
