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-405T Calibration Mass is an essential tool for laboratories in need of precise calibration. As laboratory testing becomes more advanced and auditing requirements grow stricter, it is crucial for laboratories to have the means to calibrate their own equipment.
The Calibration Mass is designed to check the span and linearity of balances, as well as calibrate electronic balances. It is specifically designed for the commonly used Span Calibration method, which involves using a single mass that is approximately equal to the capacity of the balance. This method ensures accurate readings throughout the weighing range.
The ASTM Class 4 weights are made from satin-finished stainless steel, ensuring durability and long-lasting performance. The 10kg and 20kg weights are equipped with recessed grip handles, making them easy to handle and stack. Additionally, each individual weight from 10g to 4,000g comes with a glove and a protective, foam-lined plastic case, providing extra protection during transportation and storage.
These ASTM Class 4 weights are ideal for balances that are less sensitive than 0.01g and for applications with average accuracy requirements. They are suitable for a wide range of laboratory needs, providing reliable and accurate results.
To guarantee traceability and compliance with industry standards, the Gilson OBA-405T Calibration Mass comes with a Traceable Certificate. This certificate documents traceability to the National Institute of Standards and Technology (NIST), as well as 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.
In conclusion, the Gilson OBA-405T Calibration Mass is a highly reliable and accurate tool for laboratories that need to calibrate their own balances. With its ASTM Class 4 weights, recessed grip handles, and included Traceable Certificate, this calibration mass ensures precise measurements and offers the necessary documentation for traceability and compliance.
