How big of a RISK are YOU willing to take?

The Risks of Using End-of-Life Calibration Equipment

While our products are known for their long life, continuing to rely on instruments that have reached end-of-life or end-of-service status can pose serious risks to your business. Once a product reaches this stage, spare parts and repairs are no longer guaranteed. A sudden, non-repairable failure could halt your calibration operations for weeks or even months — disrupting customer service, delaying production, and causing unexpected costs.

Plan Ahead and Stay Supported

Understanding when your equipment will reach end-of-service is the first step to minimizing downtime. Planning ahead ensures you have time to budget for new instruments, integrate them into your workflow, and take advantage of modern technology that improves accuracy, efficiency, and safety. Our team can help you identify at-risk equipment, plan replacements, and transition smoothly to newer models that keep your lab running without interruption.
