Hierarchy of Calibration Organizations
The calibration hierarchy helps us to record the sequence of calibrations performed on an instrument from a reference standard to the final measuring system.
Calibration
Instrumentation Calibration helps us to maintain and verify sensor accuracy. Different field instruments typically Flow, Pressure, Temperature, Level, etc.
Difference between Accuracy and Precision
Accuracy is how close a value to its True Value. Precision is how repeatable a measurement is. Learn the difference between them with examples.
Why Calibration is Important?
Calibration plays an important role in quality control. If an instrument is not calibrated we may suffer loss of our health, money or safety.
Importance of Unit Measurement
Any measurement has two parts – a number and a unit of measurement. The unit of measurement is very important in calibration.
Selection of Master Instrument for Calibration
We compare the reading of Unit Under Calibration (UUC) with reference to Master Instrument. Therefore the selection is very important.
History of Measurement
You measure a lot of things daily. When did man measure something for the first time? Let’s learn the history of measurement.
How to Calibrate pH Electrode?
The step-by-step procedure described how to calibrate your pH electrode using a standard two-point calibration.
What is Reliability Centered Maintenance? (RCM)
Reliability centered maintenance (RCM) is a tool used to identify potential problems and designed to optimize maintenance programs.
