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-411W Calibration Mass is a high-quality calibration weight designed to meet the increasing demands of laboratory testing and auditing. As laboratories are required to calibrate their own balances more frequently, this ASTM Class 4 weight provides an accurate and reliable solution.
The OBA-411W Calibration Mass is specially designed for span and linearity calibration of electronic balances. It can be used with both the Span Calibration method, which uses a single mass approximately equal to the balance's capacity, and the Linearity Calibration method, which allows for multiple mass settings. By selecting zero, center, and full span mass settings, users can minimize deviation throughout the balance's weighing range.
Constructed from satin-finished stainless steel, this ASTM Class 4 weight offers exceptional durability and longevity. The 10kg and 20kg weights feature recessed grip handles for easier handling and stacking, ensuring convenience and safety in various laboratory environments.
For added protection and organization, each individual weight from 10g to 4,000g comes with a foam-lined plastic case and a glove to prevent contamination. This thoughtful design allows for easy transportation and storage, keeping the weights in optimal condition for accurate calibration.
The ASTM Class 4 weights are suitable for balances that are less sensitive than 0.01g and applications with average accuracy requirements. Whether you're working in a scientific laboratory or an industrial setting, these weights provide the accuracy needed to meet your specific needs.
To further meet regulatory requirements, the Gilson OBA-411W Calibration Mass includes an NVLAP Weight Calibration Certificate. This certificate ensures compliance with ISO, FDA, ANSI, and other necessary certifications. With a report format and content that meets NVLAP standards, you can confidently provide evidence of accurate and reliable calibration.
In summary, the Gilson OBA-411W Calibration Mass is a versatile and dependable solution for calibrating electronic balances. With its ASTM Class 4 construction, protective case, and NVLAP Weight Calibration Certificate, this weight offers the precision and compliance necessary for laboratory testing and auditing.
