With a solid experience in weight and mass calibration, API supports you in all your mass measurement needs.
OIML weight from 1 mg to 50 kg
Classes E0, E1 and E2
These weights, except in E0, conform in terms of material (roughness, magnetization, etc.) in form and marking to the international recommendation OIML R111.
Class E1 weights are intended to ensure traceability between national mass standards and weights of lower classes.
Class E2 weights are intended for the calibration of lower class weights and for use with Class I (special precision) weighing instruments. It is strongly recommended to deliver these weights with a calibration certificate.
