Calibration and repair services are companies that calibrate and repair laboratory and scientific instruments, test and measurement equipment, and industrial sensors. They are located across North America and around the world.

Services

Selecting calibration and repair services requires an understanding of services offered.

• Field testing is performed on-site at a client’s facility in order to minimize downtime.
• Bench testing is performed off-site, usually at a lab or shop owned by the calibration and repair service. Some bench testing companies provide pick-up and delivery services. Others offer a replacement or exchange program.
• Warranty work is performed by calibration and repair services that are certified or approved by original equipment manufacturers (OEM).
• Troubleshooting, diagnostic or corrective maintenance is done to correct an existing problem.
• Preventative maintenance is designed to prevent equipment failure before a problem occurs.    
  

Standards and Certifications

Calibration and repair services meet quality requirements and certifications from a number of organizations. Some of these include:

• American Association for Laboratory Accreditation (A2LA)
• National Voluntary Laboratory Accreditation Program (NVLAP)
• American National Standards Institute (ANSI)
• National Institute of Standards and Technology (NIST)
• International Standards Organization (ISO)

Applications

Calibration and repair services differ in terms of expertise. Some companies specialize in the preventative maintenance or calibration of acoustic, avionic, environmental, fiber optic, marine, medical, and geophysical instruments. Others troubleshoot and adjust displays and panel meters, electrical and electronic test equipment, industrial computers, and process instruments. Calibration and repair services that rebuild, replace, and repair analytical instruments and laboratory equipment are commonly available. Analytical instruments include shakers, environmental test chambers, laboratory ovens, mechanical test equipment, chillers, baths, and sample preparation equipment. Laboratory equipment includes spectrometers, microscopes, chromatographs, pH meters, TOC analyzers, colorimeters, titrators, diffractometers and other specialized instruments.
