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.
Ultra Class weights boast weight tolerances 40—50% tighter than ASTM Class 1 and equal to or exceeding OIML Class E2. Ultra Class 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.
Ultra Class weights are perfect for analytical and sensitive balances and applications that demand superior accuracy.
The Gilson OBA-204 Calibration Mass, Ultra Class, 50g, is an essential tool for laboratories seeking to calibrate their own balances with precision and accuracy. As testing becomes more sophisticated and auditing of laboratory equipment becomes more frequent, having reliable calibration masses is crucial.
This calibration mass is designed to check the span and linearity of electronic balances. It is commonly used in the Span Calibration method, which involves a one-point calibration using a single mass that is approximately equal to the capacity of the balance. Some balances also support the Linearity Calibration method, which allows the user to select multiple mass settings, minimizing deviation throughout the weighing range.
What sets the Gilson OBA-204 apart is its Ultra Class designation. These weights offer weight tolerances that are 40—50% tighter than ASTM Class 1 and meet or exceed OIML Class E2 standards. This level of precision makes them highly suitable for analytical and sensitive balances that require superior accuracy.
The Ultra Class weights are made of highly polished stainless steel, giving them a smooth and durable surface that is resistant to corrosion. The 10kg and 20kg weights are equipped with recessed grip handles, making them easier to handle and stack. Additionally, each individual weight from 10—4,000g comes with a protective, foam-lined plastic case and a glove, ensuring their safety during storage and handling.
Whether you need to calibrate your laboratory balance or perform precise measurements in analytical applications, the Gilson OBA-204 Calibration Mass, Ultra Class, 50g, is the perfect choice. With its exceptional accuracy, durable construction, and convenient accessories, this calibration mass is a reliable tool for any laboratory seeking to maintain the highest standards of measurement precision.
