North American Calibration Labs
Located in San Luis Obispo, CA, our A2LA accredited North American Calibration lab services all Crystal products for customers outside Europe, and JOFRA products for North American customers. For over 20 years, the San Luis Obispo Lab has been the main service center for Crystal Engineering products, combining high quality service and repair with quick turnaround times. In 2019, the lab was expanded to service the JOFRA temperature calibrators, saving North American customers valuable time and money. Our friendly technicians have years of experience servicing Crystal products and can quickly and confidently provide the highest quality customer service. This includes firmware updates, functional tests, and safety tests.

Located in Largo, FL, our second North American service location handles the Mansfield & Green (M&G) line of products, including pneumatic and hydraulic deadweight testers and our line of pneumatic and hydraulic pumps.

The years of producing these primary standards allow our technician to quickly and properly diagnose any issue you may have.
