What is the accuracy of measuring instruments?

Businesses are placing greater emphasis on maintaining precise and reliable measuring instruments to ensure quality control and regulatory compliance. The accuracy of a measuring instrument reflects how closely its measured value aligns with the true value.

We offer comprehensive calibration services to uphold this accuracy, enabling businesses to enhance operational efficiency and meet stringent industry standards. Ensuring the accuracy of measuring instruments is essential for delivering consistent product quality and ensuring safety.

Why the accuracy of measuring instruments is important

Monitoring the accuracy of measuring instruments is essential for sustaining high standards of product quality, safety, and operational efficiency. Key challenges include determining the optimal frequency for calibration of measuring instruments to assure precision, as well as accounting for environmental factors such as fluctuations in temperature and humidity – both of which affect measurement accuracy.

Regular use of instruments can lead to wear and tear, resulting in drift from calibrated settings that necessitates periodic recalibration. Additionally, compliance with evolving industry standards and regulatory requirements is crucial to remain compliant. Institutions like the Physikalisch Technische Bundesanstalt have established benchmarks for precise instruments, and adhering to these standards helps mitigate the risk of legal non-compliance and protects the company’s reputation.

Measuring instrument calibration services backed by DAkkS accreditation not only support compliance but also contribute to cost savings by reducing waste and rework, improving decision-making processes and overall productivity.

What our accuracy of measuring instruments services include

Our experts can help you achieve accuracy of measuring instruments through:

  • Type examination

    We provide type examinations for portable electrical systems, measuring instruments, instruments used for 4 Pascal tests, and leak test systems used for testing class N, P, and H chimney systems (EN 1443) and regulated suction devices in accordance with DVGW standard G 625.

  • Qualification testing and type examination  covering testing of construction and building requirements, mechanical tests, testing of power supply and the software, tests with test gases and real gases, determination of non-conforming measurement results and measurement uncertainty, testing of calculation procedures, and testing of temperature and pressure measurements.
    Test specifications:
    • VDI 4206 Part 1 / VDI 4206 Part 2 / VDI 4206 Part 3 / VDI 4206 Part 4.
    • DIN EN 50379-1 / DIN EN 50379-2 / DIN EN 50379-3.
  • Calibration of various instruments

    We provide differential pressure gauges and pressure gauge calibration, as well as accuracy adjustments for other measuring instruments.
