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 4 weights are satin-finished 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 4 weights are perfect for most balances less sensitive than 0.01g and applications having average accuracy requirements.
The Gilson OBA-404 Calibration Mass is designed for laboratories that require accurate and precise calibration of their balances. As testing methods become more sophisticated and laboratory equipment is subjected to rigorous auditing, it is essential to have reliable calibration tools at hand.
This calibration mass is specifically classified as ASTM Class 4, ensuring its compliance with industry standards. Made from high-quality stainless steel, it features a satin finish that not only adds to its durability but also gives it a sleek and professional appearance. The recessed grip handles on the 10kg and 20kg weights make it easier to handle and stack, ensuring convenience and efficiency during calibration procedures.
The Gilson OBA-404 Calibration Mass is ideal for balances that are less sensitive than 0.01g and applications with average accuracy requirements. Whether it's checking span and linearity or calibrating electronic balances, this calibration mass provides reliable and consistent results.
To facilitate transportation and protection, each individual weight from 10g to 4,000g comes with a glove and a foam-lined plastic case. This ensures that the calibration mass remains in pristine condition for extended periods of time, preventing any potential damage that could compromise its accuracy.
The Span Calibration method, commonly used with this calibration mass, 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, such as zero, center, and full span. This method significantly reduces deviation throughout the weighing range of the balance, ensuring accuracy across various measurement points.
In conclusion, the Gilson OBA-404 Calibration Mass is a reliable and essential tool for laboratories seeking accurate and precise calibration. Its ASTM Class 4 classification, satin-finished stainless steel construction, and included protective case demonstrate its commitment to quality and durability. Whether it's for span calibration or linearity calibration, this calibration mass provides the necessary accuracy for a wide range of applications.
