Troemner - Troemner 2KG Calibration Weight

Applications & Use Cases

• Calibrating analytical balances and precision scales in pharmaceutical research and development.
• Ensuring accuracy of weighing instruments in quality control laboratories for food and beverage production.
• Verifying the performance of balances used in chemical and material science laboratories.
• Maintaining traceability of measurements in metrology and calibration service providers.

Typical Specifications

Weight Material

Typically high-grade stainless steel, such as Troemner Alloy 8, for corrosion resistance and stability.

Design

Commonly cylindrical, often supplied with a protective case for handling and storage.

Nominal Mass

This unit is a 2kg weight; other common nominal masses for this class of equipment range from 1mg to 20kg.

Density

Approximately 7.95 g/cm³ at 20°C for stainless steel weights.

ASTM Class

Typically ASTM Class 3 or higher, suitable for calibrating balances with readability down to 0.001 g.

Certification

Often supplied with ISO/IEC 17025 accredited certificates or traceable certificates.

Maintenance

Requires careful handling to avoid damage or contamination; periodic re-certification is essential.

Frequently Asked Questions

• Why is the ASTM class important for calibration weights?

  The ASTM class specifies the tolerance and uncertainty of the weight, indicating its suitability for calibrating balances of different precisions. Higher classes (e.g., Class 0, 1) have tighter tolerances for more sensitive balances.

• What is the significance of the material used for calibration weights?

• How often should calibration weights be re-certified?

• Can this 2kg weight be used to calibrate a 4kg capacity balance?

• What is the purpose of the protective case?
