FAQ
What is calibration?
Calibration is the process of checking and adjusting a measuring instrument’s accuracy by comparing it against a known, trusted standard. It ensures that instruments provide consistent, reliable readings that comply with safety and quality standards. The risks of not calibrating include false passes or false failures in production resulting in costly reworks or discarding products.
Why should I calibrate?
Instruments naturally experience wear, drift, and environmental impact over time, which can compromise their performance. There are costs and risks associated with not calibrating equipment regularly. Calibration ensures measurement accuracy. Routine calibrations are your prescription for the continued health and performance of your instrument.
What is ISO 17025 calibration?
ISO/IEC 17025 is the international standard for testing and calibration laboratories. It sets out requirements for the competence, impartiality, and consistent operation of laboratories, ensuring the accuracy and reliability of their testing and calibration results. Compliance with ISO/IEC 17025 demonstrates a laboratory’s commitment to quality, technical proficiency, and scientific rigor.
At ITS, we are proud to hold ISO/IEC 17025:2017 accreditation for the calibration services listed in our Scope of Accreditation, giving our clients confidence in the quality and reliability of their calibration results.
What types of instruments do you calibrate and service?
We calibrate a wide range of instruments including pH meters, pH instruments, gas analyzers, pressure transmitters, level transmitters, flow meters, conductivity sensors, temperature measurement devices, Ozone monitor and more. If you have a specific instrument, please contact us to confirm calibration capabilities.
