Why is Calibration Required?
All measuring devices need calibration simply because it is impossible to make perfect hardware that does not require any form of periodic error correction. Making hardware good enough to eliminate the need for error correction for most devices would be extremely expensive for manufacturers. The best balance is to make the hardware as good as practically possible, balancing performance and cost. Therefore, calibration becomes an essential tool to monitor and improve the measurement accuracy of your equipment.

As an FDA or ISO regulated company, you may be audited for your compliance with FDA and/or ISO regulatory requirements – either GLP (Good Laboratory Practices) or GMP (Good Manufacturing Practices). These governing bodies require that the display accuracy of all instruments that have an effect on the quality of your product or research be verified (calibrated) over a specified interval of time. As stated in part 58 of the Code of Federal Regulations:

"Equipment used for generation, measurement, or assessment of data shall be adequately tested, calibrated and/or standardized."

Consistent calibration ensures the quality of your internal processes. Whatever situations compel you to control or monitor temperature, humidity, pressure, or other conditions also require you to calibrate the instruments used to control or monitor those conditions. The calibration process can detect potential parts wear in your instrumentation and is a good indicator to go by in setting up a regularly scheduled preventative maintenance program. Failure to properly calibrate and maintain your process or R&D laboratory equipment represents a safety risk and a risk to the integrity and credibility of your equipment and processes.

Calibrating your equipment can help you evaluate performance characteristics critical in refining your maintenance program. Equipment calibration can enable you to dial in maintenance frequency and reduce excessive costs. Equipment calibration can also provide product cost savings. If your scale is under reading by as little as 1%, you could be giving away a lot of costly product over time.


"Since 1996 we have received the same level of service from Biometrix...Excellent! Whether it is a request for same day calibration at the lab or in-house, I know customer satisfaction is a top priority. I like the fact that I can relax and know my calibration needs are being handled by a professional, knowledgeable staff. Kudos for a job well done, every time!"
