The Colorado Metrology Laboratory offers a wide range of calibration and testing services. These services are available to both the public and private sectors on a fee basis. Calibration services are offered in the areas of mass (weight), volume, length, grain moisture, and time/frequency in both customary and metric units. The laboratory is capable of performing calibrations at varying levels of accuracy.

Many standards do not need calibration at the highest levels and in fact, may not be stable enough to maintain high accuracy. We will gladly answer your questions regarding what kind of calibration will best suit your needs by contacting us. We can also assist in specifying standards that you are looking to purchase. Please see FAQs to help answer some general questions.
