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-413W Calibration Mass, ASTM Class 4, 4000g, NVLAP is a high-quality calibration weight designed for laboratories that require accurate and reliable calibration of their weighing equipment. As testing and auditing of laboratory equipment become more sophisticated, it is essential for laboratories to have the capability to calibrate their own balances.
This calibration mass is specifically designed for span and linearity calibration of electronic balances. It is commonly used in the Span Calibration method, which involves using a single mass that is approximately equal to the capacity of the balance. This method ensures that the balance is accurately calibrated and minimizes deviations throughout its entire weighing range. Some balances also utilize the Linearity Calibration method, which allows the user to select multiple mass settings, further enhancing the balance's accuracy.
The Gilson OBA-413W Calibration Mass is made of satin-finished stainless steel, conforming to ASTM Class 4 standards. This ensures the weight's durability and accuracy. For easier handling and stacking, the 10kg and 20kg weights come with recessed grip handles. Additionally, each individual weight from 10g to 4,000g is accompanied by a glove and a protective, foam-lined plastic case, ensuring that they remain in optimal condition for accurate calibration.
These ASTM Class 4 weights are suitable for most balances that are less sensitive than 0.01g and applications that have average accuracy requirements. They provide reliable and precise calibration for a wide range of laboratory equipment.
Furthermore, the Gilson OBA-413W Calibration Mass comes with an NVLAP Weight Calibration Certificate. This is particularly beneficial for users who need to provide certification to meet ISO, FDA, ANSI, or other regulatory requirements. The report format and contents of the certificate comply with NVLAP standards, ensuring that the calibration process is traceable and meets the necessary quality assurance standards.
Overall, the Gilson OBA-413W Calibration Mass, ASTM Class 4, 4000g, NVLAP offers a reliable and accurate solution for laboratories in need of precise calibration of their weighing equipment. Its high quality, durability, and compliance with industry standards make it an essential tool for maintaining and verifying the accuracy and reliability of laboratory balances.
