Descripción del producto
SW stainless steel weights series are built and calibrated according to OIML R111 accuracy requirements. All of these weights are adjusted as close to the upper positive tolerance range of one higher accuracy class as possible. This gives a longer life span against worn out.
Class F1 weights are ideal for testing and calibration of high precision balances. They are made of one single piece of stainless steel (monobloc).
Class F2 weights are ideal for routine testing of high precision balances.
Class M1 weights are ideal for routine testing of general scales. They are designed with an adjusting cavity at bottom which allows optimized and easy adjustment.
All set of weights and individual weights of 1kg or higher come with an aluminum box, while individual weights 100g ~ 500g come with plastic cylinder enclosure.
Definitions and Applications of Various Weight Classes (extracted from OIML R111)
- Class F1: – Weights intended for use in the verification or calibration of class F2 weights and for use with weighing instruments of special accuracy class I and high accuracy class II.
- Class F2: – Weights intended for use in the verification or calibration of class M1 and possibly class M2 weights. Also intended for use in important commercial transactions (e.g. precious metals and stones) on weighing instruments of high accuracy class II.
- Class M1: – Weights intended for use in the verification or calibration of class M2 weights, and for use with weighing instruments of medium accuracy class III.
