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.
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-407W Calibration Mass is an essential tool for laboratories that need to calibrate their own balances. With the increasing demand for sophisticated testing and frequent auditing of laboratory equipment, it has become necessary to have reliable calibration equipment.
The Calibration Mass is designed to check the span and linearity of electronic balances. It is commonly used for one-point calibration, where a single mass is used that is equal to the capacity of the balance. This ensures accurate weighing throughout the balance's range. Additionally, some balances use the Linearity Calibration method, which allows users to select multiple mass settings for increased accuracy.
The Gilson OBA-407W Calibration Mass is made from satin-finished stainless steel, ensuring durability and longevity. The weights are ASTM Class 4, making them suitable for most balances that are less sensitive than 0.01g and applications with average accuracy requirements. The 10kg and 20kg weights come with recessed grip handles, making them easier to handle and stack. They are also equipped with a glove and a protective foam-lined plastic case for added convenience and protection during transportation and storage.
For users who must provide certification to ISO, FDA, ANSI, or other requirements, the Gilson OBA-407W Calibration Mass comes with an NVLAP Weight Calibration Certificate. The certificate ensures that the weights meet the necessary standards and comply with NVLAP requirements. This adds an extra layer of credibility and reassurance for laboratories that need to meet rigorous certification standards.
In conclusion, the Gilson OBA-407W Calibration Mass is a reliable and essential tool for laboratories that need to calibrate their balances. Its ASTM Class 4 weights, together with the included NVLAP Weight Calibration Certificate, provide accuracy, durability, and compliance with industry standards. Whether for span calibration or linearity calibration, this product is a must-have for laboratories that value precision and reliability in their weighing processes.
