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 included Traceable Certificate documents traceability to NIST and compliance with ASTM or OIML specifications. The Traceable Certificate includes nominal value and correction, date of calibration, accuracy class, customer name and purchase order number.
The Gilson OBA-401T Calibration Mass is an essential tool for laboratories in need of precise calibration for their balances. As testing and auditing become more sophisticated, it is essential for laboratories to take control of their own calibration processes.
This calibration mass is specifically designed for span and linearity calibration of electronic balances. The Span Calibration method, which is commonly used, utilizes a single mass that is approximately equal to the capacity of the balance. On the other hand, some balances use the Linearity Calibration method, which allows users to select multiple mass settings such as zero, center, and full span of the balance's capacity. This method ensures minimal deviation throughout the weighing range.
Crafted with precision and durability in mind, the ASTM Class 4 weights are made of satin-finished stainless steel. The 10kg and 20kg weights are equipped with recessed grip handles for easier handling and stacking. Additionally, each individual weight from 10g to 4,000g comes with a glove and a protective, foam-lined plastic case, ensuring the longevity and safety of the weights.
These ASTM Class 4 weights are perfect for balances that are less sensitive than 0.01g and applications with average accuracy requirements. They provide reliable and accurate results for a wide range of laboratory needs.
Furthermore, the Gilson OBA-401T Calibration Mass comes with a Traceable Certificate that documents its traceability to NIST (National Institute of Standards and Technology) and compliance with ASTM or OIML specifications. This certificate includes important information such as the nominal value and correction, date of calibration, accuracy class, customer name, and purchase order number. With this certificate, users can have confidence in the accuracy and reliability of their calibration process.
In conclusion, the Gilson OBA-401T Calibration Mass is a top-quality tool for laboratories that need precise calibration for their balances. Its ASTM Class 4 weights, convenient features, and included Traceable Certificate make it a reliable and efficient solution for laboratories of all sizes and needs.
