Instrument Maker Earns Accreditation for Laboratory and Field Calibrations
The scope of accreditation includes temperature, flow and pressure for both laboratory and on-site calibration. Also included within the scope are electrical parameters associated with current, voltage, resistance and frequency pertaining to internal laboratory calibration.
Who needs calibration? Instruments that are not part of a regular calibration program with established calibration intervals run the risk of operating out of tolerance. Small deviations can up to tens of thousands of dollars, impacting production, profit and loss. Endress+Hauser offers this example: A temperature transmitter that indicates 284°F (140°C) steam temperature when the actual temperature is 286°F (141.1°C) can cost a company $10,000 per year. The 2°F (~1°C) temperature difference would amount to 44 lb of wasted steam per hour.
