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 1 masses are highly polished 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 1 masses are perfect for analytical balances and applications requiring first-order accuracy.
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-307T Calibration Mass is a high-quality calibration tool designed for laboratories seeking accuracy and reliability. With the increasing need for sophisticated testing and regular equipment auditing, it has become essential for laboratories to calibrate their own balances.
The primary purpose of the Gilson OBA-307T Calibration Mass is to check span and linearity and calibrate electronic balances. It offers two commonly used calibration methods – Span Calibration and Linearity Calibration. The Span Calibration method involves using a single mass equal to the balance's capacity, while the Linearity Calibration method allows users to select zero, center (half span), and full span mass settings. This helps minimize deviation throughout the weighing range of the balance.
The Gilson OBA-307T Calibration Mass is made from highly polished stainless steel, meeting the strict ASTM Class 1 standards. This ensures durability and accuracy, making it suitable for analytical balances and applications requiring first-order accuracy.
For easy handling and stacking, the 10kg and 20kg weights are equipped with recessed grip handles. Additionally, each individual weight from 10g to 4,000g comes with a protective, foam-lined plastic case and a glove. This ensures the weights remain in optimal condition and protected during transportation and storage.
To further enhance its reliability, the Gilson OBA-307T Calibration Mass includes a Traceable Certificate. This certificate documents traceability to the National Institute of Standards and Technology (NIST) and compliance with ASTM or OIML specifications. It includes information such as the nominal value and correction, calibration date, accuracy class, and customer details. This certificate provides confidence in the calibration process and serves as proof of traceability for audits or quality assurance purposes.
Calibrating balances has never been easier with the Gilson OBA-307T Calibration Mass. Its high-quality construction, convenient handling, and traceable certification make it an indispensable tool for laboratories seeking accurate and reliable measurements.
