Inside Our Operations: Probata’s Calibration Laboratory Journey

standard calibration processes

In the realm of precision measurement and quality assurance, our calibration laboratory at Probata serves as the cornerstone, ensuring the accuracy and reliability of measurement instruments. As an accredited laboratory, certified by the American Association for Laboratory Accreditation (A2LA), our operations are conducted with meticulous precision, adhering to the highest industry standards. Let us take you through the inner workings of our laboratory, both in-house and mobile, to provide insight into our standard calibration processes.

In-House Calibration Process:

1. Facility Setup:

At Probata, our in-house calibration lab operates within controlled environments, adhering to strict temperature, humidity, and cleanliness standards. Our facility is equipped with state-of-the-art equipment, including reference standards and calibration benches, to facilitate precise measurements.

2. Instrument Reception:

Our process begins with the receipt of instruments requiring calibration. Each instrument is meticulously logged into our database, documenting its make, model, serial number, and calibration history. This information ensures traceability and accountability throughout the calibration process.

3. Pre-Calibration Checks:

Before calibration, instruments undergo thorough pre-calibration checks by our technicians to assess their condition and functionality. We inspect for physical damage, wear, or contamination that may affect measurement accuracy. Any anomalies are documented for further evaluation.

4. Calibration Procedure:

Calibration at Probata follows standardized procedures, typically defined by national or international standards such as ISO/IEC 17025 and ANSI/NCSL Z540-1-1994. These standards ensure that our calibration processes are well-documented, systematic, and technically valid. ISO/IEC 17025 focuses on general requirements for the competence of testing and calibration laboratories, while ANSI/NCSL Z540-1-1994 provides additional guidance specific to calibration laboratories, including requirements for equipment, procedures, and traceability.

5. Adjustment and Certification:

If deviations from the reference standards are detected, our technicians make precise adjustments to bring instruments into alignment. Once calibrated, instruments are issued with calibration certificates detailing the results, adjustments made, and validity period. These certificates serve as evidence of compliance with quality standards. Although, in any instance, the instrument may not require any adjustment if it is performing as expected.

6. Quality Assurance:

Quality control measures are integral to our calibration process. We conduct regular audits, proficiency testing, and inter-laboratory comparisons to ensure the accuracy and reliability of our calibration results. Continuous improvement initiatives drive the enhancement of our processes and methodologies.

7. Turnaround Time:

For in-house calibration services, Probata offers a turnaround time of 7-10 business days, ensuring prompt calibration while maintaining our high standards of accuracy and reliability.

mobile calibration services

Mobile Calibration Operations:

1. On-Site Services:

Our mobile calibration labs offer the convenience of on-site calibration services, catering to industries with large or immovable equipment. Equipped with portable reference standards and calibration equipment, our technicians travel to client facilities to perform calibration tasks.

2. Equipment Mobilization:

Prior to deployment, our technicians carefully select and calibrate portable equipment suitable for on-site operations. This includes portable calibrators, standards, and measurement tools necessary to perform accurate measurements in diverse environments.

3. On-Site Calibration:

On-site calibration procedures mirror those of our in-house labs, albeit with adaptations to accommodate varying environmental conditions and equipment constraints. Our technicians ensure proper setup, environmental control, and safety protocols during on-site operations.

4. Documentation and Reporting:

Following calibration, our technicians generate on-site calibration certificates documenting the results, adjustments, and compliance status of instruments. These certificates are immediately provided to clients, ensuring transparency and accountability.

5. Client Collaboration:

Mobile calibration services at Probata emphasize collaboration and communication with clients to address specific requirements and concerns. Our technicians provide insights and recommendations for instrument maintenance, calibration intervals, and regulatory compliance.


At Probata, our calibration laboratory, whether in-house or mobile, operates with unwavering commitment to accuracy, reliability, and customer satisfaction. Through standardized procedures, meticulous attention to detail, and continuous improvement initiatives, we uphold the integrity of measurement instruments across diverse industries. Whether within the controlled environment of our dedicated facility or on the move with our mobile unit, our calibration technicians play a vital role in ensuring the precision and reliability of measurement processes.
