Weighing Pan: Capacity 0.1 g to 5000 g, Diameter 80-200 mm

Q: How often should a weighing pan be calibrated?

Weighing pans themselves don't require calibration, but the complete balance system should be verified daily with certified weights and undergo formal calibration annually per ISO/IEC 17025 requirements.

Q: Can different material weighing pans affect measurement accuracy?

Yes, material choice impacts thermal conductivity, magnetic properties, and electrostatic characteristics. Stainless steel provides optimal stability for most applications, while specialized materials address specific needs like chemical resistance or reduced magnetism.

Component Specifications

Definition

The weighing pan is a critical component of precision balances and analytical balances, serving as the sample placement surface for mass determination. It is designed to provide stable, vibration-damped support for materials while maintaining minimal interference with measurement accuracy. Typically constructed from corrosion-resistant materials, it interfaces directly with the balance's load cell or electromagnetic force restoration mechanism through a suspension system that isolates environmental disturbances.

Working Principle

The weighing pan functions as the primary contact point for samples, transferring gravitational force through a mechanical linkage (often a parallelogram suspension system) to the balance's transducer. This force is converted into an electrical signal proportional to mass. Modern designs incorporate static dissipation, magnetic damping, and temperature compensation to maintain measurement integrity.

Materials

Stainless steel (304 or 316 grade), aluminum alloy (anodized), glass, or advanced polymers (PTFE-coated). Anti-static coatings and passivated surfaces are common for corrosion resistance and contamination prevention.
