Repair and Warranty

Document Actions
Our staff of experienced service technicians can provide fast factory repair service, using exclusively authorized components and modules. The repair price includes the cost of calibrating the unit to restore it to its original factory specifications. Each repair is backed by a 90-day warranty as more specifically described in the Keithley terms. We can provide repair service on many obsolete models, depending on availability of parts.

Extended Warranty

You will typically realize hundreds of dollars of savings over “per-incident” repair prices.

Peace of mind

You will eliminate unbudgeted repair expenses by purchasing additional product coverage.
