A DAkkS Accredited Calibration Laboratory is a laboratory that has been independently assessed and accredited by DAkkS (Deutsche Akkreditierungsstelle GmbH), Germany’s National Accreditation Body, to perform calibrations in accordance with the internationally recognized ISO/IEC 17025 standard.

DAkkS accreditation demonstrates that a laboratory has the technical competence, qualified personnel, validated methods, traceable reference standards, and quality management systems required to produce accurate, reliable, and repeatable calibration results.

Calibration certificates issued by a DAkkS-accredited laboratory are internationally recognized through the International Laboratory Accreditation Cooperation Mutual Recognition Arrangement (ILAC MRA), allowing customers to demonstrate traceability and measurement confidence worldwide.

Why DAkkS Accreditation Matters

Choosing a DAkkS-accredited laboratory provides confidence that your measurements are:

• Traceable to the International System of Units (SI)
• Performed according to ISO/IEC 17025
• Internationally recognized through ILAC MRA
• Accepted by regulatory agencies and quality auditors worldwide
• Supported by documented measurement uncertainty
• Performed using validated procedures and calibrated reference standards

Benefits of Using a DAkkS Accredited Calibration Laboratory

A DAkkS-accredited calibration laboratory helps organizations:

• Improve product quality
• Meet ISO 9001 and ISO/IEC 17025 quality requirements
• Support GMP and FDA-regulated manufacturing
• Demonstrate measurement traceability during audits
• Reduce measurement uncertainty
• Improve confidence in critical process measurements
• Ensure globally accepted calibration certificates

Applications

DAkkS-accredited calibration services are commonly used for:

• Dew Point Meters
• Chilled Mirror Hygrometers
• Relative Humidity Instruments
• Temperature Sensors
• Climate Chambers
• Environmental Monitoring Systems
• Industrial Gas Moisture Analyzers
• Laboratory Reference Standards

Why Choose Process Insights?

Unlike many calibration providers, Process Insights combines manufacturer expertise with accredited calibration services. Our laboratory uses MBW chilled mirror hygrometers, widely recognized as reference standards by national metrology institutes and calibration laboratories worldwide.

Benefits include:

• DAkkS-accredited laboratory
• ISO/IEC 17025 accredited procedures
• ILAC MRA recognized certificates
• Traceability to SI units
• Low measurement uncertainty
• Factory-trained metrology specialists
• Manufacturer calibration expertise
• Global customer support

Why Chilled Mirror Technology?

Chilled mirror hygrometers are considered the reference technology for humidity calibration because they measure dew point directly rather than estimating humidity from sensor response.

Advantages include:

• Direct thermodynamic measurement
• Excellent long-term stability
• Minimal drift
• High repeatability
• Low uncertainty
• Superior traceability

This makes chilled mirror technology the preferred reference for calibrating humidity and dew point instruments across industry and research.

Frequently Asked Questions 

What is humidity calibration?

Humidity calibration verifies the accuracy of instruments that measure relative humidity, dew point, or moisture by comparing them against traceable reference standards under controlled environmental conditions.

Why is ISO/IEC 17025 accreditation important?

ISO/IEC 17025 accreditation confirms that a calibration laboratory has demonstrated technical competence, validated methods, traceable standards, and a quality management system capable of producing reliable and repeatable results.

How often should humidity instruments be calibrated?

Calibration frequency depends on the application, operating environment, quality requirements, and manufacturer recommendations. Critical manufacturing and regulated industries often calibrate annually or according to internal quality procedures.

Why are chilled mirror hygrometers used as reference standards?

Chilled mirror hygrometers provide direct thermodynamic measurements of dew point with exceptional stability and low uncertainty, making them the preferred reference standard for accredited humidity calibration laboratories.

Can you calibrate instruments from other manufacturers?

Yes. In addition to MBW instruments, Process Insights provides calibration services for many third-party humidity and dew point instruments where appropriate.

What is an ILAC MRA calibration certificate?

An ILAC MRA certificate is issued by an accredited laboratory whose results are recognized internationally through the International Laboratory Accreditation Cooperation, supporting global traceability and acceptance of calibration results.
