With more sophisticated testing and more frequent auditing of laboratory equipment, it has become increasingly necessary for laboratories to calibrate their own balances. Calibration Masses are offered to check span and linearity and calibrate electronic balances. The commonly used Span Calibration method uses one-point calibration with a single mass approximately equal to the capacity of the balance. Some balances use the Linearity Calibration method which allows the user to select multiple mass settings, normally defined as zero, center (half span), and full span of the balances capacity. This method minimizes deviation throughout the balance's weighing range.
Ultra Class weights boast weight tolerances 40—50% tighter than ASTM Class 1 and equal to or exceeding OIML Class E2. Ultra Class masses are highly polished stainless steel. Recessed grip handles are part of the 10kg and 20kg weights for easier handling and stacking. Individual weights from 10—4,000g include a glove and protective, foam-lined plastic case.
Ultra Class weights are perfect for analytical and sensitive balances and applications that demand superior accuracy.
NVLAP Weight Calibration Certificate is included for users who must provide certification to ISO, FDA, ANSI or other requirements. Report format and contents comply with NVLAP requirements.
The Gilson OBA-201W Calibration Mass, Ultra Class, 10g, NVLAP is a high-quality product designed specifically for laboratories in need of precise calibration. As lab equipment is being tested and audited more rigorously, it has become increasingly important for laboratories to have the capability to calibrate their own balances. This calibration mass offers an effective solution for checking span and linearity and calibrating electronic balances.
The Span Calibration method, commonly used in the industry, involves a one-point calibration using a single mass that is approximately equal to the capacity of the balance. On the other hand, the Linearity Calibration method allows users to select multiple mass settings, including zero, center (half span), and full span of the balance's capacity. This method is preferred as it minimizes deviation throughout the weighing range.
With weight tolerances 40-50% tighter than ASTM Class 1 and meeting or exceeding OIML Class E2 standards, the Ultra Class weights are highly accurate. Made from highly polished stainless steel, these weights are not only precise but also durable. The 10kg and 20kg weights even come with recessed grip handles for easier handling and stacking.
Furthermore, the individual weights ranging from 10g to 4,000g are provided with a glove and a protective, foam-lined plastic case, ensuring their safety during transportation and storage.
Designed for analytical and sensitive balances, the Ultra Class weights are perfect for applications that demand superior accuracy. In addition, this product includes an NVLAP Weight Calibration Certificate, which is essential for users who need to provide certification in accordance with ISO, FDA, ANSI, or other requirements. The certificate's format and content comply with NVLAP standards, giving users confidence in the accuracy and reliability of their calibrated balances.
Overall, the Gilson OBA-201W Calibration Mass, Ultra Class, 10g, NVLAP is the ideal solution for laboratories seeking highly accurate and reliable calibration weights.
