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-417T Calibration Mass Set is an essential tool for laboratories that require accurate calibration of their balances and equipment. As testing and auditing standards become more rigorous, it is crucial for laboratories to have the means to calibrate their own instruments.
This calibration mass set is designed to check span and linearity, as well as calibrate electronic balances. It offers two commonly used calibration methods: the Span Calibration method and the Linearity Calibration method. The Span Calibration method uses a single mass that is approximately equal to the capacity of the balance, while the Linearity Calibration method allows the user to select multiple mass settings, minimizing deviation throughout the weighing range.
The ASTM Class 4 weights included in this set are made of satin-finished stainless steel, ensuring durability and accuracy. The 10kg and 20kg weights even feature recessed grip handles for easier handling and stacking. Each individual weight from 10g to 4,000g comes with a glove and a protective, foam-lined plastic case, ensuring safe storage and transportation.
The ASTM Class 4 weights are perfect for balances that are less sensitive than 0.01g and for applications with average accuracy requirements. They provide reliable and precise calibration for a wide range of laboratory equipment.
What sets this calibration mass set apart is its Traceable Certificate. This certificate documents the traceability of the weights to the National Institute of Standards and Technology (NIST) and the compliance with ASTM or OIML specifications. It includes important information such as the nominal value and correction, date of calibration, accuracy class, customer name, and purchase order number. This certificate ensures that the calibration process is carried out with the utmost accuracy and accountability.
In conclusion, the Gilson OBA-417T Calibration Mass Set is an indispensable tool for laboratories that require reliable and accurate calibration of their balances. With its ASTM Class 4 weights, versatile calibration methods, and Traceable Certificate, this set provides the necessary means to meet testing and auditing standards with confidence and precision.
