NNP 1Kg Weight

Applications & Use Cases

• Calibration of laboratory balances and scales in pharmaceutical research and development.
• Verification of weighing equipment accuracy in biotech production facilities.
• Quality control checks for precision instruments in analytical laboratories.
• Setting and adjusting industrial scales used for ingredient measurement.
• Routine accuracy testing in university and research institutions.

Typical Specifications

Typical capacity

This specific unit is a 1Kg weight. Calibration weights are available in a wide range of denominations, from milligrams to multiple kilograms.

Power supply

Calibration weights are passive devices and do not require a power supply.

Material

Commonly made from stainless steel or brass, often with a polished finish to resist corrosion and wear.

Accuracy class

Typically available in OIML (International Organisation of Legal Metrology) classes such as E1, E2, F1, F2, M1, M2, M3, or ASTM (American Society for Testing and Materials) classes, indicating their tolerance and precision.

Construction

Solid, single-piece construction for stability and long-term accuracy, often with a handle or knob for safe handling on higher denominations.

Maintenance requirements

Requires careful handling to prevent damage or contamination, and periodic professional recalibration to maintain certified accuracy.

Frequently Asked Questions

• What is the significance of a calibration weight's accuracy class?

  The accuracy class (e.g., OIML E2, F1) defines the maximum permissible error for the weight. Higher classes like E1 and E2 are used for calibrating high-precision analytical balances, while lower classes like M1 are suitable for industrial scales.

• How often should calibration weights be recalibrated?

• Can this 1Kg weight be used with any balance?

• What care is required for calibration weights?

• Is a calibration certificate included with used weights?
