Question 1

What is the Eagle Stainless Steel Test Weight, Class F2 and what is it used for?

Accepted Answer

The Eagle Stainless Steel Test Weight Class F2 is a precision calibration weight designed to verify and calibrate lab scales and balances. It uses corrosion‑resistant stainless steel with a polished finish for easy cleaning, and the nominal masses offered with this style are 25 mg and 80 mg, making it suitable for calibrating a range of instruments.

Question 2

What nominal masses are available with this weight?

Accepted Answer

This weight set includes nominal masses of 25 mg and 80 mg variants, providing small reference masses for accurate calibration of mg‑readability scales.

Question 3

What does F2 class mean for calibration accuracy?

Accepted Answer

F2 is a calibration weight grade that indicates a defined tolerance suitable for routine laboratory calibration. It offers reliable accuracy for general scale checks, while ultra‑high‑precision weights (higher grades) are used for more demanding tasks.

Question 4

What materials and finishing are used, and how does that affect durability and cleaning?

Accepted Answer

It's made from high‑quality stainless steel with a polished finish, offering excellent durability and corrosion resistance. The polished surface also makes it easier to wipe clean after use.

Question 5

How do I use this weight to calibrate a scale?

Accepted Answer

Steps: 1) Turn on the scale, level it, and tare to zero. 2) Use tweezers to place the weight on the weighing pan and note the reading. 3) Compare the reading to the nominal mass and adjust the scale’s calibration if needed. 4) Remove the weight, re‑tare, and allow readings to stabilize. 5) Clean the weight with a soft cloth after use.

Question 6

How should I clean and maintain this test weight?

Accepted Answer

Wipe with a soft lint‑free cloth. Avoid harsh solvents or abrasives. Keep the weight in a dry environment and handle with care to maintain the polished finish and accuracy.

Question 7

Which scales or balances is this weight compatible with?

Accepted Answer

This weight is designed for scales and analytical balances that can read in the milligram range and have sufficient capacity for 25 mg or 80 mg. Always verify your instrument’s readability and maximum capacity before use.

Question 8

What are common use cases for this weight?

Accepted Answer

Typical applications include routine calibration of laboratory balances, quality control in manufacturing, and educational demonstrations where exact mg‑level reference masses are needed.

Question 9

How does this compare to other calibration weights available on Fepy?

Accepted Answer

Question 10

Are there storage or accessory considerations to maximize performance?

Accepted Answer

Store in a clean, dry environment and consider a dedicated test weight tray or case to prevent nicks and contamination. When not in use, keep the weight away from moisture and store it separately from other metal items to avoid scratching.

Question 11

Is this weight a good value for the money for typical lab calibration needs?

Accepted Answer

Yes, for routine mg‑level calibration, the combination of F2 accuracy, stainless steel durability, and easy maintenance provides solid value. If you require ultra‑high precision or specialized tolerances, you might consider higher‑grade weights, but for everyday calibration tasks this weight offers dependable performance at a reasonable price.
