An E2 Class Weight Box is a set of precision weights used for calibrating high-accuracy weighing instruments like analytical balances, typically containing weights ranging from 1mg to 200g, and classified as "E2 Class" due to their high accuracy level, making them suitable as a reference standard for calibrating lower class weights like F1 or M1 class weights; they are commonly used in quality control labs and research facilities requiring precise measurements.
Accuracy:
Considered a high-precision standard, offering a higher level of accuracy than lower class weight boxes.
Application:
Primarily used for calibrating analytical balances and other high-readability weighing instruments.
Weight range:
Usually includes weights from 1mg to 200g, with different shapes like squares, triangles, and pentagons depending on the weight value.
Material:
Typically made from high-quality stainless steel with a polished finish.
Calibration:
These weight boxes are often supplied with a certificate from a recognized calibration laboratory.
