The terms “calibration” and “adjustment” are often misunderstood, and sometimes even considered the same process. Both are essential for the proper functioning of equipment, to ensure greater accuracy of measurement and consistent readings, but they are unique processes.

Calibration

  • The process in which you compare the values or measurements indicated by certain instrument or system against those indicated by a standard (Calibrator), under controlled test conditions.

  • The output and accuracy of the standard are known, so the measurement of a specific quantity can easily be compared with comparable measurements from the IUT. A calibration report is then created, which includes details like the pass/fail results of each parameter, operating or test conditions, industry specifications, acceptable tolerances, etc.

Aside from proper maintenance all medical instruments that make use of electronic components for accuracy will need calibration one way or another. Routine equipment calibration is needed to ensure grayscale accuracy.  Maintaining properly calibrated equipment provides measurement consistency, reduced measurement errors and measurement accuracy.

A pressure transducer is an instrument that measures pressure of gases and liquids.  These pressure transducers are also used for measuring other variables related to pressure, such as speed, flow, altitude and water level.  Pressure transducers are used to detect the fluid’s force and give a mechanical output reading.  Helping to monitor and regulate the pressure of the fluid and make the needed alterations.

Pipette calibration is important for good laboratory practice and is a vital part of any lab regime, where precise volumes of fluid need transferring or diluting.

Pipettes typically wear down or break each year, even with normal usage. The wear and tear can impact performance measurement, produce poor test results, delays, rework and waste. Breakdowns can be noticeable, but most are silent failures that are overlooked such as old sealing mechanisms, cracked shaft, corroded piston, and using the incorrect tip.
