This Rice Lake single calibration weight is engineered for professionals who require uncompromising accuracy in mass measurement. As an ASTM Class 1 weight, it represents one of the highest levels of precision available for commercial and laboratory use, providing the confidence needed for critical calibrations, scale testing, and quality assurance protocols. Its construction adheres to strict metrological standards, ensuring reliable performance that supports traceability requirements.
The weight is machined from solid, corrosion-resistant stainless steel to a precise density of 7.84 g/cm³, a critical factor for high-accuracy applications where air buoyancy corrections may be necessary. The inclusion of a sealed adjustment cavity allows for fine-tuning during manufacture to achieve its exact mass value, which is then secured to prevent tampering or environmental contamination. This design guarantees the weight's stability and preserves its calibration over time, making it a dependable investment for any metrology program.
