Compare Our Calibration Lab with Other Calibration Services
Not all calibration laboratories deliver the same level of accuracy, traceability, or measurement uncertainty. When calibrating humidity, dew point, frost point, and temperature instruments, choosing the right laboratory can directly impact product quality, regulatory compliance, and measurement confidence.
Process Insights operates a DAkkS-accredited ISO/IEC 17025 calibration laboratory that provides internationally recognized calibration services using MBW chilled mirror hygrometers, the reference technology trusted by national metrology institutes, accredited laboratories, and leading instrument manufacturers worldwide. Our calibration certificates are recognized internationally through the ILAC Mutual Recognition Arrangement (ILAC MRA), providing traceability accepted across global industries.
Our up-to-date accreditation certificate is always available at the following link: Process Insights CAL DAkkS.
What is a DAkkS Accredited Calibration Laboratory
What Should You Compare When Choosing a Calibration Laboratory?
Many calibration providers offer similar services, but several factors determine the quality and reliability of the calibration results.
Consider the following:
- ISO/IEC 17025 accreditation
- DAkkS or equivalent national accreditation
- International ILAC MRA recognition
- Documented measurement uncertainty
- Calibration traceability
- Reference instrument technology
- Technical expertise
- Long-term stability of reference standards
- Environmental controls
- Manufacturer support
- Turnaround time
- Global service capabilities
Why ISO/IEC 17025 Accreditation Matters
ISO/IEC 17025 is the internationally recognized standard for testing and calibration laboratories.
An accredited laboratory demonstrates:
- Technical competence
- Validated calibration procedures
- Qualified personnel
- Traceable reference standards
- Controlled environmental conditions
- Documented measurement uncertainty
- Continuous quality management
Choosing an accredited laboratory gives customers greater confidence that calibration results are accurate, repeatable, and internationally accepted.
Why Chilled Mirror Technology Is the Preferred Reference Standard
One of the most important differences between calibration laboratories is the reference technology used during calibration.
MBW chilled mirror hygrometers measure humidity by directly determining the temperature at which condensation forms on a mirror surface. Because this is a primary physical measurement rather than an inferred sensor response, chilled mirror instruments are widely used as transfer standards by national metrology institutes and accredited calibration laboratories.
Benefits include:
- Direct humidity measurement
- Excellent repeatability
- Extremely low drift
- Low measurement uncertainty
- Long-term stability
- High confidence calibration

Why Measurement Traceability Matters
Measurement traceability establishes an unbroken chain of comparisons to recognized national or international standards.
Traceable calibration helps organizations:
- Meet ISO quality requirements
- Pass regulatory audits
- Demonstrate measurement confidence
- Improve manufacturing consistency
- Reduce quality disputes
- Maintain customer confidence
Frequently Asked Questions
Why should I use an ISO/IEC 17025 accredited calibration laboratory?
An accredited laboratory has demonstrated technical competence, validated procedures, and traceable measurements that are independently assessed by a national accreditation body.
What is DAkkS?
DAkkS (Deutsche Akkreditierungsstelle) is Germany’s national accreditation body responsible for accrediting calibration laboratories according to ISO/IEC 17025.
What is ILAC MRA?
The ILAC Mutual Recognition Arrangement enables calibration certificates issued by accredited laboratories to be accepted internationally, reducing duplicate testing and simplifying global compliance.
Why are chilled mirror hygrometers used as reference standards?
Because chilled mirror hygrometers directly measure the condensation point of water vapor, they provide highly stable, repeatable, and low-uncertainty humidity measurements suitable for calibration reference standards.

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.
