On-Site Calibration Services

J.A. King offers onsite services for everything from high capacity scale calibration to precision measurement equipment calibration and everything in between. Our onsite technicians will come to your facility and perform calibration service on your equipment, whether you have an entire tool crib of equipment to calibrate or just a few pieces.

On-site services are sometimes the only option for permanently installed equipment like ovens or truck scales, equipment that is just too large to transport, or even equipment that just can’t be out of service long enough to leave your facility. J.A. King is here to ensure your equipment is operating accurately and efficiently, even if you can’t send it to our laboratory.

Our large network of facilities makes it cost effective to offer quick onsite calibration services to a vast territory in the U.S. We have a fleet of mobile calibration units throughout our network of laboratories which cover over 15 states. Onsite services are offered at all of our full service locations, within a 120 mile radius of our laboratory zip code. Check out the J.A. King Locations page to see the hours of your nearest location and fill out our form to contact a local team member to get a quote for onsite services!
