CALIBRATION – KEY WORD IS COMPARISON

Definitions

Basic: The comparison of a measurement or source of unverified certainty with a measurement of known uncertainty.
Detailed: Calibration is a set of operations that establish, under specified conditions, the relationship between values of quantities indicated by a measuring instrument or measuring system, or values represented by a material measure or a reference material, and the corresponding values realized by standards.

All products are given a specification by their manufacturer. This indicates the performance a product should operate to and maintain over a set period of time.

As components age and the product undergoes changes in temperature or humidity or sustains mechanical stress, performance of the product gradually degrades.

This is called drift. When this happens your test results become unreliable and any process that the product is a part of has lost it’s integrity and validity.

While drift cannot be eliminated, it can be detected through the process of calibration.

Pressure: Gauges, Calibrators, Transducers, Transmitters, Indicators, Switches, Valves.
Temperature: Sensors, Indicators, Thermocouple & RTD Transmitters, Calibrators, PRTs, Thermistors.
Electrical/Electronic: Multimeters, AC/DC Signal Sources, Clamp Meters, Tachometers, Ohmmeters, Decade Boxes, Loop Devices, Power Supplies.
Frequency: Signal Generators, Oscilloscopes, Frequency Meters, Timer Counters.
And Much More: Incorporate various test equipment for Flow, Level, Mass, Mechanical, Dimensional, and more.

Additionally benchtop instruments such as dry block calibrators and pressure pumps are used when connected to modules performing testing applications.
For electrical calibration adaptors for clamp meter calibration and optical tachometer calibration are available, and benchtop instruments for specialist applications.
