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.
NVLAP Weight Calibration Certificate is included for users who must provide certification to ISO, FDA, ANSI or other requirements. Report format and contents comply with NVLAP requirements.
The Gilson OBA-402W Calibration Mass, ASTM Class 4, 20g, NVLAP is an essential tool for laboratories that need to calibrate their own balances. With the increasing importance of accurate testing and frequent auditing, it is essential for labs to have reliable calibration equipment.
This calibration mass is designed to check the span and linearity of electronic balances. It can be used with both the Span Calibration method, which involves using a single mass approximately equal to the balance's capacity, and the Linearity Calibration method, which allows for multiple mass settings. The Linearity Calibration method minimizes deviation throughout the weighing range of the balance.
The ASTM Class 4 weights are made of satin-finished stainless steel, ensuring long-lasting durability. 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 glove and a protective, foam-lined plastic case, ensuring their safe storage and transportation.
These ASTM Class 4 weights are perfectly suited for balances that are less sensitive than 0.01g and for applications that have average accuracy requirements. They offer reliable and accurate calibration for a wide range of laboratory needs.
For users who need to provide certification to ISO, FDA, ANSI, or other requirements, this calibration mass includes an NVLAP Weight Calibration Certificate. The certificate complies with NVLAP requirements and provides assurance of the mass's accuracy and reliability.
In conclusion, the Gilson OBA-402W Calibration Mass, ASTM Class 4, 20g, NVLAP is a reliable and durable calibration tool that is essential for laboratories. With its versatility and accuracy, it allows for precise calibration of electronic balances, making it a valuable asset for any laboratory that requires accurate measurements.
