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-213W Calibration Mass, Ultra Class, 4000g, NVLAP is a high-quality product designed for laboratory use. With the increasing need for accurate calibration of laboratory equipment, this calibration mass provides reliable and precise results.
The Span Calibration method is commonly used and involves the use of a single mass that is approximately equal to the capacity of the balance. This helps check span and linearity, ensuring accurate measurements. Some balances also utilize the Linearity Calibration method, which allows the user to select multiple mass settings, further minimizing deviation throughout the weighing range.
The Ultra Class weights offered by Gilson are of superior quality and accuracy. These weights have weight tolerances that are 40-50% tighter than ASTM Class 1 and are equal to or even exceed OIML Class E2 standards. Made of highly polished stainless steel, these weights are built to last. The 10kg and 20kg weights even come with recessed grip handles, making them easier to handle and stack.
Whether you are working with analytical or sensitive balances, the Ultra Class weights are perfect for your needs. They provide the level of accuracy demanded by such applications, ensuring reliable and consistent results.
For users who require certification to ISO, FDA, ANSI, or other requirements, the NVLAP Weight Calibration Certificate is included with each purchase. This certificate complies with the requirements set by NVLAP and includes all the necessary information in the proper format.
To further protect these weights, each individual weight from 10-4,000g comes with a glove and a protective, foam-lined plastic case. This ensures that the weights are safeguarded during storage and transportation, maintaining their accuracy and longevity.
Overall, the Gilson OBA-213W Calibration Mass, Ultra Class, 4000g, NVLAP is a top-quality product that meets the demanding requirements of laboratory calibration. With its superior accuracy and included certification, it is the ideal choice for ensuring accurate measurements and complying with industry standards.
