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-414W Calibration Mass is a reliable and essential tool for laboratories in need of accurate and efficient balance calibration. As the demand for more precise testing and increased auditing of laboratory equipment continues to grow, it is crucial for laboratories to have the capability to calibrate their own balances. This calibration mass, classified as ASTM Class 4, ensures that laboratories can perform span and linearity checks as well as calibrate electronic balances to maintain accuracy.

The Span Calibration method, commonly used in laboratories, involves a single-point calibration using a mass that is approximately equal to the capacity of the balance. On the other hand, the Linearity Calibration method enables users to select multiple mass settings, including zero, center (half span), and full span of the balance's capacity. This method minimizes deviation across the entire weighing range of the balance.

Crafted with satin-finished stainless steel, the ASTM Class 4 weights offer durability and reliability. The 10kg and 20kg weights are designed with recessed grip handles, making them easier to handle and stack. Additionally, the individual weights ranging from 10g to 4,000g come with a protective, foam-lined plastic case and a glove to ensure safe and secure storage.

The ASTM Class 4 weights are perfect for balances that are less sensitive than 0.01g and for applications that have average accuracy requirements. These weights provide accurate and reliable results, making them suitable for a wide range of laboratory applications.

Furthermore, the Gilson OBA-414W Calibration Mass includes an NVLAP Weight Calibration Certificate, ensuring that users can provide certification to ISO, FDA, ANSI, or any other relevant requirements. The report format and contents comply with the strict standards set by NVLAP, guaranteeing accurate and reliable certification documentation.

In conclusion, the Gilson OBA-414W Calibration Mass is a high-quality product that enables laboratories to calibrate their balances with precision and accuracy. With its ASTM Class 4 classification, recessed grip handles, and included NVLAP Weight Calibration Certificate, this calibration mass is designed to meet the demands of modern laboratories and regulatory requirements.
