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.
ASTM Class 1 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.
ASTM Class 1 masses are perfect for analytical balances and applications requiring first-order 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-309W Calibration Mass is a necessary tool for laboratories seeking to calibrate their electronic balances. With the increasing demand for sophisticated testing and frequent auditing of laboratory equipment, it has become essential to have reliable calibration masses.
When it comes to calibration, two commonly used methods are the Span Calibration method and Linearity Calibration method. The Span Calibration method utilizes a single mass that is approximately equal to the capacity of the balance, allowing for one-point calibration. On the other hand, the Linearity Calibration method allows the user to select multiple mass settings, including zero, center (half span), and full span of the balance's capacity. This method ensures minimal deviation throughout the weighing range of the balance.
The Gilson OBA-309W Calibration Mass is an ASTM Class 1 mass, made of highly polished stainless steel. This ensures its durability and reliability for accurate calibration. The 10kg and 20kg weights come with recessed grip handles, making them easier to handle and stack. Additionally, individual weights ranging from 10g to 4,000g are provided with a glove and a protective, foam-lined plastic case for safe and convenient storage.
These ASTM Class 1 masses are specifically designed for analytical balances and applications that require first-order accuracy. They are ideal for laboratories that demand precision and reliability in their measurements.
Furthermore, the Gilson OBA-309W Calibration Mass comes with an NVLAP Weight Calibration Certificate. This certificate is essential for users who are required to provide certification to ISO, FDA, ANSI, or other regulatory bodies. The report format and contents of the certificate fully comply with NVLAP requirements, ensuring the credibility and accuracy of the calibration process.
In conclusion, the Gilson OBA-309W Calibration Mass is a high-quality and reliable tool for laboratories in need of calibration for their electronic balances. Its ASTM Class 1 construction, along with the included NVLAP Weight Calibration Certificate, make it an essential choice for laboratories seeking accurate and traceable measurements that comply with industry standards.
