Digital Low Resistance Ohmmeter (DLRO) Calibration Lab Services

Digital Low Resistance Ohmmeter (DLRO) Calibration


request a transcat calibration service quick quoteWith high-level precision, Transcat performs accredited calibrations of digital low resistance ohmmeters (DLROs). We calibrate DLROs of all types, including those that provide the four-wire measurement method to eliminate lead resistance. Accurate, periodic calibration helps to ensure that your ohmmeter tests rapidly and correctly as you measure the resistance of circuit breaker contacts, bus bar joints, aircraft frame bonds, wire, cable and more. We also want you to have instruments in optimal condition for repetitive, production testing. You can rely on Transcat’s industry-leading electrical calibrations for all of your DLRO models with various low resistance capabilities, output options, and features.

Reduce Risk with Accredited DLRO Calibration Services

Digital Low Resistance Ohmmeter (DLRO) Calibration Lab Services'Service engineers need precision accuracy and safety during all of their low resistance measurement operations. That’s why we calibrate the DLRO with high-level accuracy, no matter its resolution, range, accuracy and applications. You can take steps to avoid erroneous readings that lead to costly, and possibly dangerous, risks by choosing a calibration provider that:

  • Calibrates all models and sizes of DLROs, including those from industry leading manufacturers such as Megger, AEMC, Hioki, and Extech
  • Offers proven, yet competitively priced, ISO/IEC 17025-accredited laboratory capabilities with NIST traceability.
  • Performs testing precisely to manufacturer specifications, or to your customized parameters, to ensure repeatable readings within your instrument’s specified accuracies.
  • Provides fast turnarounds for onsite, in-process, or laboratory calibration options, which are all accredited.
