When testing the accuracy and calibrating your various pieces of weighing equipment, calibration weights are essential. Regular calibration of your balances is essential for accurate weighing of your equipment. Biotechnical Services Inc. provides the best calibration weights services in Los Angeles.

Types of Calibration Weights

· F1/F2 OIML calibrate and test precision electronic balances.

· E1 OIML calibrate and test micro-analytical balances.

· E2 OIML calibrate and test analytical balances.

· M1 OIML is standard for calibrating and testing scales.

Classes of Calibration Weights

· ATSM Class 1 weights are normally constructed using highly polished stainless steel.

· ATSM Class 4 calibration is used with applications with average accuracy and sensitivity of fewer than 0.01 grams.

· Ultra-class weights have a sophisticated design to provide superior accuracy and are normally used for test applications, sensitive balances.

· NIST class weights are constructed using cast iron. Designed for less sensitive and higher capacity scales and balances.

Ways to properly handle the calibration scales

· Your calibration weights should always be in their original packaging to protect them from dust, contamination and to avoid mixing the weights up.

· One should always avoid handling the calibrated weights with bare hands as it could be risky and may result in damage to your weights.

· Before starting your testing or calibration, check for any contamination, such as dust or water. If you notice any contamination, clean your weight with a microfiber cloth or soft brush or blow the dust off.
