On-Site Calibration and Repair

Qal-Tek’s On-Site Calibration & Repair (OSCaR) service is a complete ISO17025, A2LA accredited, nationally reaching mobile laboratory! With an autonomous annual route scheduler, 3 OSCaR trucks, along with 3 physical locations; our logistics team works efficiently with you through the whole process of scheduling, and tracking all your equipment, their calibrations, your regulatory certificates, product training, and more. When our logistics team schedules an OSCaR technician to arrive, he comes equipped with our proprietary, cloud based, calibration and tracking system known as mEyeCal. While on-site, and with the use of this database tool, he can accurately calibrate, track, and manage your equipment right there alongside your RSO/equipment manager. This flagship service minimizes your downtime, provides you ultimate convenience, and saves you time and money!

When the OSCaR vehicle comes to you, there is no need for a “transfer of custody” or a “declaration of dangerous goods” for shipping! Our OSCaR trucks and technicians are equipped and experienced to calibrate up to 6 NDG’s a day at your location, and are capable of calibrating your lab test & measurement equipment (CMT) in the same visit! Additionally, the technicians can provide on-site leak testing, area/site surveys, and can confirm and certify your gauge cases are within NRC and Type A package compliance as well as DOT regulations.

If in the event that your equipment needs to be repaired at one of our fixed facilities, our logistics team will draw up the necessary paperwork for you and the OSCaR technician. Thus making the shipping, transfer, repair, and inventory update, seamless and efficient for you!

Our company is focused on providing the most convenient service solutions in the market.
