All instruments manufactured by Tinker & Rasor can be evaluated and repaired at our facilities in New Braunfels, Texas. It is highly recommended and in some cases mandatory for equipment to be calibrated and certified on an annual basis.

Only authorized facilities outside of Tinker & Rasor who calibrate to standards traceable to NIST can perform calibrations and issue annual certifications. Please, contact Tinker & Rasor for a list of these locations. The use of any non-authorized repair and calibration facilities will void any and all warranties. Repairs and calibration of Tinker & Rasor equipment is complicated and requires specialized equipment and experience. It is necessary to make sure that you are using an authorized repair facility before hand. Current calibration records are on file and available upon request.
