OIML Class F1 – F1 class laboratory weights are precision-crafted for high-accuracy calibration needs and comply with OIML standards. Weights of 10g and above (up to 50kg) feature a two-piece construction with an adjusting cavity, ensuring exceptional stability and precision. Unlike E-class weights, which have no markings, F-class weights are visually distinguished by punch markings that indicate their denomination.
Positioned just below E-class weights in terms of accuracy, F1 weights are ideal for calibrating F2 weights and all lower accuracy classes. They are also suitable for calibrating balances of Classes 3 and 4, making them a versatile and reliable choice for laboratory and industrial calibration needs.
Appropriate for calibrating high-precision top loading balances with a readability as low as 0.01 g to 0.001 g.
OIML Class F2 – F2 class laboratory weights are designed for reliable performance in moderate-accuracy calibration tasks. Like their F1 counterparts, weights of 10g and above are constructed with a two-piece design featuring an adjusting cavity for precise tuning. They are easily distinguishable from E-class weights due to their punch-marked denominations.
F2 weights come after F1 in the accuracy hierarchy and are primarily used to calibrate M1 weights and all lower classes. Additionally, they are suitable for calibrating balances of Classes 3 and 4, offering a practical solution for everyday calibration needs in laboratories and industrial settings.
