A Guide to Calibration Weights
Most labs use calibration weights to ensure that their balances provide accurate readings. It is important to note, however, that they are not all made the same. Weights that are used for calibration are categorized according to their accuracy or tolerance. Weights are classified in different sets, including ASTM, OIML, and NIST. As well as this, different weights are certified differently.
P R O D U C T S
STAINLESS STEEL
Stainless Steel Polished Precision Reference Weights
Stainless steel calibration weights are designed for long-term stability, with capacities ranging from 1 gram to 50 kilograms. These weights are best suited for analytical and precision balances.
Available individually or as a set.
CAST IRON
Cast Iron Industrial Trade Weights
Cast iron weights are available in OIML M1 class and offer higher capacities to calibrate larger scales.
Available individually or as a set.
Large Capacity Cast Iron Weights
OIML Cast Iron Weights in the M1 class are suitable for calibrating scales with a high capacity, such as industrial platforms and floor scales. OIML testing requirements ensure accurate results for each weight.
Available individually or as a set.
