Adam Equipment, a worldwide manufacturer of scales and balances for professionals, is now offering OIML E2 class calibration weights to customers in both North and Latin America. The weight sets are certified to International Organisation of Legal Metrology (OIML) standards. Adam has previously offered OIML class weights only to customers in Europe, Australia and Africa.

Adam Equipment's OIML E2 class weights provide excellent accuracy and are ideal for calibrating analytical and precision balances. The weights come in sets of 1g – 200g or 1mg – 200g, and are crafted of highly polished stainless steel to help prevent corrosion. The weight sets are packaged in a lined aluminum box, complete with forceps and white cotton glove.

Adam Equipment's calibration weights can simplify external calibration on any lab balance. For labs that perform high-precision testing, using OIML class weights for calibration ensures traceability to national and international standards. Certificates of traceability for all of Adam Equipment's OIML class weights are available at the time the weights are purchased.

In addition to OIML weights, Adam offers class 0, 1, 2, 3, and 4 ASTM weights, individually or in sets. ASTM weights are based on standards set by the American Society for Testing and Materials.

To achieve optimum calibration results, it's important to take proper care of the weights. To keep them clean, always store weights in a protective lined case. Even small dust particles on the weights can affect calibration results on highly sensitive balances. Using gloves or tweezers to handle weights can protect the surface from fingerprints, dirt or lint. If any residual dust from the air is present on the weight, use a soft, lightweight brush to help remove it before starting the calibration process. If there is a temperature difference between the weights and the balance, wait to calibrate until the weights adjust to the same temperature as the balance.

Balance calibration is essential for accurate weighing results. For more information on calibration weights and advice on how to calibrate your balance, visit
