Class F Calibration Weights: NIST, 25kg, Traceable
With more advanced testing and more frequent auditing of laboratory equipment, laboratories are now required to calibrate their own balances. Calibration Masses are used to check span and linearity and calibrate electronic balances. The most common Span Calibration method uses one-point calibration with a single mass approximately equal to the balance’s capacity. Some balances use the Linearity Calibration method which allows the user to select multiple mass settings, usually defined as zero, center (half span) and full span of the balance’s capacity. This method minimizes deviation throughout the balance’s weighing range.
NIST Class F Calibration Masses are available for higher capacity balances and scales. Cast iron with integral grip handles.
NIST Class F weights are for higher capacity, less sensitive balances and scales.
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 Calibration Mass, NIST Class F, 25kg, Traceable is the perfect tool for laboratories that need to calibrate their own balances. With more advanced testing and more frequent auditing of laboratory equipment, it’s essential to have calibration masses on hand.
This calibration mass is used to check span and linearity and calibrate electronic balances. It has two common calibration methods - Span Calibration and Linearity Calibration. The Span Calibration method uses a single mass approximately equal to the balance’s capacity, the Linearity Calibration method allows the user to select multiple mass settings, usually zero, center (half span) and full span of the balance’s capacity. This method minimizes deviation throughout the balance’s weighing range.
NIST Class F Calibration Masses are high quality and for higher capacity balances and scales. Cast iron with integral grip handles, these weights are durable and easy to handle.
One of the key features of the Calibration Mass is the included Traceable Certificate. This certificate documents traceability to NIST and compliance with ASTM or OIML specifications. It includes nominal value and correction, date of calibration, accuracy class, customer name and purchase order number. With this certificate you can have full confidence in your calibrations.
Whether you are a laboratory doing routine calibrations or a facility that requires precise measurements, the Calibration Mass is a must have tool. Its high quality, compatibility with higher capacity balances and Traceable Certificate make it an essential instrument for any laboratory or facility that values accuracy and precision.
Calibration Weight Features and Benefits
Calibration weights are precision instruments to ensure accuracy and reliability of weighing devices. These weights are manufactured to meet strict tolerance standards to ensure high precision in every measurement. Made of durable materials like stainless steel or cast iron, they are built to withstand harsh environments and heavy use, suitable for laboratory and commercial use.
The ergonomic design of calibration weights makes them easy to handle, reducing the risk of damage during use. Many calibration weights come with optional certifications like NIST Traceable or NVLAP Certificates which documents their traceability to national standards. Compliance to international standards like ASTM and OIML ensures these weights are globally accepted and trusted.
Calibration weights are available in various weight classes and capacities to suit different applications. Whether for laboratory balances or commercial weighing devices, these weights provide the accuracy and reliability for precise measurement. The benefits of using calibration weights are to ensure accuracy of weighing devices, meet regulatory requirements for legal metrology, reduce errors and increase efficiency and productivity in various industries.
Calibration and Certification Process
The calibration and certification process of calibration weights involves a series of tests and evaluations to ensure the weights meet strict tolerance standards. First, the weight is calibrated to its nominal value using a reference standard. This step ensures the weight is accurate.
Then the weight is verified to ensure it meets the required tolerance standards. This verification step is critical to the integrity of the weight’s accuracy. Once verified the weight is certified by a recognized authority like NIST or NVLAP. This certification documents the weight’s accuracy and traceability, assures it meets national and international standards.
Recalibration is necessary to ensure the weight remains accurate over time. The certification process may involve different types of certificates, NIST Traceable Certificate which documents traceability to NIST standards and NVLAP Certificate which is certification to ISO, FDA, ANSI or other requirements. A Calibration Certificate documents the weight’s accuracy and reliability to meet quality control and auditing purposes.
Selecting the Right Test Weights for Your Application
Selecting the right test weights for your application involves several factors. First select a weight class that meets the required tolerance standards for your specific application. The capacity of the weight is also important; it should match your application whether for laboratory balances or commercial weighing devices.
The material of the test weight is another consideration. Durable materials like stainless steel or cast iron are preferred for its corrosion resistance and long lasting performance. Certification is also a key factor; depending on your application you may need NIST Traceable or NVLAP certification to meet national and international standards.
Industry standards such as ASTM and OIML should also be considered to ensure the test weights meet the relevant regulations. Specific applications like laboratory balances require high precision test weights with tight tolerance standards, commercial weighing devices require test weights that meet regulatory requirements for legal metrology. In pharmaceutical industry test weights must meet stringent standards for accuracy and reliability to ensure measurement integrity.
Protecting Calibration Weights
Protecting calibration weights involves several steps. Proper storage is important; weights should be stored in a dry and secure location to prevent damage and contamination. Handle the weights with care to avoid scratches and other forms of damage.
Cleaning the weights regularly is necessary to prevent corrosion and contamination which can affect its accuracy. Recalibration of the weights at regular intervals ensures it remains accurate and reliable over time.
Using accessories can further enhance the durability and protection of calibration weights. Weight cases provides a storage solution, weight handles makes it easier to handle the weights, reduces the risk of damage. Weight gloves can also be used to prevent scratches and damage during handling. By following these steps you can maintain the accuracy and reliability of your calibration weights and its long term performance.
