Endress+Hauser gained accreditation to ISO17025 by the American Association for Laboratory Accreditation (A2LA) for laboratory and field calibration of process instrumentation.
Their new LaPorte Calibration and Service Center in LaPorte, Texas is the main laboratory; the accreditation covers laboratory calibrations in LaPorte as well as field calibrations at a customer’s location.
The scope of accreditation includes the principles of flow, pressure and temperature for 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.
A second A2LA accredited Endress+Hauser facility is in Greenwood, IN.
Companies have been sending instrumentation to the new LaPorte facility for calibration since it opened in 2009. The lab can accommodate flow, pressure and temperature instruments from most manufacturers.
Instruments that aren’t part of a regular calibration program with established calibration intervals run the risk of operating out of tolerance. Small deviations can cost up to tens of thousands of dollars having an impact on production, profit and loss.
For example, a temperature transmitter that indicates 284°F steam temperature when the actual temperature is 286°F can cost a company $10,000 per year. The 2°F temperature difference would amount to 44 lb of wasted steam per hour. If the unit operated for 5,000 hours per year, the inaccuracy would cost 44 lb/hr x 5000 hr x $0.045/lb of steam equal to $10,120 per year.
Customers often need calibration to ensure instrument measurement is accurate and within the limits needed to produce a quality product. This helps reduce overall business costs by minimizing quality fluctuations and associated costs. For some processes, periodic calibration to NIST standards is a requirement to comply with both quality and safety standards.
