What is Calibration?

Calibration methods come in various forms. Batch calibration indicates product samples from a manufactured lot were tested and confirmed to meet specifications. Individual calibration indicates each device produced was tested and certified. Accredited calibration offers the highest level of certainty that the device is accurate and reliable to use. Each device was individually tested in accordance with a quality standard, usually ISO 17025. The process has also been reviewed and certified by a metrologist, a third-party accreditation expert.

Why Calibration Is Key

ISO/IEC 17025 Accredited Calibration Lab

All Traceable products are provided with a Traceable Calibration Certificate from our ISO 17025 calibration laboratory and ISO Guide 34 Certified Reference Material Producer.

Timer, thermometer, hygrometer, barometer, tachometer, gauge pressure, differential pressure, scale, balance, conductivity cell, conductivity solution, conductivity meter, pH solution, salinity meter, dissolved oxygen meter, UV light meter, light meter, and caliper certificates are accredited by the American Association for Laboratory Accreditation (A2LA).

“As Found" vs “As Left”
When recalibrating your measurement device, you have the option to receive data as “As Found”, “As Left”, or both.
AS FOUND calibration data is calibration data acquired prior to any repairs or adjustments being made to the device. Essentially, it is the condition of the device “as found” when arriving to our facility for calibration. This provides the user an opportunity to ensure that the instrument was reading accurately, and within specification, while it was in use. It offers valuable information and documentation to support an end user's test results, and it also provides record-keeping on the instrument's long-term linearity and stability.
AS LEFT calibration data is calibration data acquired after any repairs or adjustments are made to the device, i.e. the condition the device was left before shipping back to you. The condition of the device used to acquire the as left data will be the same condition in which you will receive your device.
