At Klerkscale, we proudly operate as an accredited ISO/IEC 17025:2017 calibration laboratory specializing in mass metrology. Our primary mission is to ensure global compatibility in mass measurements by providing calibrations traceable to both National and International Standards (SI). This commitment is reinforced by our participation in the ILAC-MRA agreement (International Laboratory Accreditation Cooperation – Mutual Recognition Arrangement).

Measuring Standards (Weights)

• In-House Calibration: Mass pieces ranging from 1 mg to 20 kg are calibrated at our laboratory.
• On-Site Calibration: Accredited for mass calibration on-site, covering weights from 20 kg to 5,000 kg.
• Adjustment Services: Mass pieces can be adjusted to meet specific requirements or conformity standards upon request.

Weighing Instruments

Our calibration process includes comprehensive testing for accuracy and linearity, with before-and-after readings to ensure the reliability of your equipment. These readings allow you to assess if pre-calibration errors could have impacted your measurements.

Our calibration services go beyond basic measurements. We ensure your equipment operates at peak performance with the following:

• External and Internal Cleaning
• Corner Load and Eccentric Adjustments (where applicable)
• Accuracy and Linearity Tests
• Repeatability Measurements

Calibration Range:

• Laboratory Balances: 0 – 30 kg
• Commercial Scales: 30 kg – 10,000 kg
