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-208W Calibration Mass is the perfect tool for laboratories that require accurate and reliable calibration of their balances. As laboratories face more rigorous testing and auditing, it has become essential for them to calibrate their own equipment. With the Gilson OBA-208W, laboratories can easily check the span and linearity of their balances and ensure accurate measurements.

The commonly used Span Calibration method involves using a single mass that is approximately equal to the capacity of the balance. On the other hand, the Linearity Calibration method allows the user to select multiple mass settings, minimizing deviation throughout the balance's weighing range. The Gilson OBA-208W is designed to cater to both calibration methods, providing flexibility and convenience for laboratory technicians.

One of the standout features of the Gilson OBA-208W Calibration Mass is its Ultra Class designation. With weight tolerances 40—50% tighter than ASTM Class 1 and equal to or exceeding OIML Class E2, these calibration masses offer superior accuracy and precision. Made from highly polished stainless steel, the Ultra Class weights are not only durable but also visually appealing.

The 10kg and 20kg weights of the Gilson OBA-208W come with recessed grip handles, making them easier to handle and stack. This thoughtful design makes the calibration process more efficient and user-friendly. Additionally, each individual weight from 10—4,000g includes a glove and comes in a protective, foam-lined plastic case to ensure safe transportation and storage.

For laboratories that need to provide certification to ISO, FDA, ANSI, or other requirements, the Gilson OBA-208W Calibration Mass comes with a NVLAP Weight Calibration Certificate. This certificate confirms the accuracy and reliability of the calibration weights, and its format and contents comply with NVLAP requirements. With this certificate, laboratories can confidently demonstrate their adherence to industry standards.

Overall, the Gilson OBA-208W Calibration Mass offers laboratories the perfect combination of accuracy, convenience, and compliance. Whether it's for analytical and sensitive balances or applications that demand superior accuracy, this calibration mass is a reliable and indispensable tool for any laboratory.
