If you require a 3rd party calibration certification, but the caliper doesn't appear to need service, we offer remote and physical calibration certification. Note, this service does not include calibration or repair services, only a 3rd party certification.

REMOTE CERTIFICATION - $20

If you have a 5-step calibration block you can email us the following:
