What is a Class 2 weighing scale?
Class II/High
Class II scales have up to 100,000 divisions. Typical uses include laboratory weighing, weighing of precious metals and gems, and grain test scales. Our Highland portable precision balance is an example of a Class II balance.
What is D and E in weighing balance?
For Class I and Class II scales, “e” is governed by a formula that says if “d” (the displayed division) is less than “e” (the verification division), then “e” should be less than or equal to ten times “d.” To use the example of the HCB 103aM, since the “d” (0.001g) and “e” values are not equal, “e” must be no more than …
