Metrology Lab

The Kansas Metrology Laboratory provides calibration service for mass and volume for metrological traceability to the International System of Units (SI). These services are available for laboratories, government, licensed service companies, and various industries.

Standards calibrated by the laboratory include mass standards, weight carts, test measures, and provers. These types of standards are used to calibrate or check weighing and measuring devices, that are used for commercial sales, laboratory work, and manufacturing.   

The Kansas Metrology Laboratory maintains a National Institute of Standards and Technology (NIST), Certificate of Metrological Traceability. The laboratory, also, participates in inter-laboratory comparisons of standards and participates in regional metrology measurement assurance meetings to ensure that the results of the Kansas Metrology Laboratory are consistent with other metrology laboratories.

Measurements covered by the scope of the Kansas Metrology Laboratory’s NIST, Certificate of Metrological Traceability can be found at the NIST State Measurement Laboratories website.  

NOTE: KML has successfully relocated all equipment and standards to our new location in Manhattan, KS. We are working through the process of recertification to perform calibrations with NIST recognition. The plan to reopen by late summer has been postponed due to the COVID-19 pandemic. As a result, KML is now projecting Fall/Winter 2020. If you would like to schedule a calibration, please email We apologize for the inconvenience.
