ISO/IEC 17025 Accredited Weight Calibration Services
Troemner understands the importance of precision and accuracy when it comes to weights & measures.
With over 170 years of industry experience, Troemner’s staff of metrologists and calibrators possess a high level of expertise with primary and secondary mass standards. At Troemner we address every variable of our measurement process to ensure consistency of calibration, which leads to accurate results in your processes, products and services. Troemner’s foundation is built upon skill in precision measurement. Our standards are continually maintained according to NIST procedures and ISO/IEC 17025 guidelines. We are committed to reducing costs, increasing efficiencies and improving quality in support of our customers.
Troemner has the largest collection of mass comparators in the world, and we are constantly purchasing new comparators to keep our capabilities up-to-date to maintain the highest level of precision. Additionally, seven newly acquired robots allow Troemner to provide impeccable service by increasing not only precision, but also efficiency. We also use proprietary software to track the performance of our equipment and standards to assure that our calibration system is in control. Magnetic permeability testing and magnetic susceptibility testing are incorporated into our processes and utilize a susceptometer.
