Reliability of Line Width Calibration Standards can only be guaranteed if they are inspected and Re-certified at regular intervals. We recommend that this be done annually or at the first sign of damage or contamination. All Standards shipped to us for Re-certification receive our highest priority and will be returned within five working-days.

We take great pride in providing our customers with personal, convenient and expedient service. Our customers always come first! If you have any questions or comments regarding our products or services, please click on Contact Us or feel free to call us at 650-941-8300.
