Out of Production items are not Out of Service or Obsolete, they are simply replaced by the next Generation Instrumentation. These Out of Production instruments remaining in stock are either new or have seen gentle use as demonstration equipment at trade shows. All units sold are fully functional, calibrated, and are provided with a one (1) year limited parts and full labor warranty. Limited parts warranty indicates that some replacement parts may be limited in supply or no longer available. Failure of these limited parts may leave the unit incapacitated should failed parts no longer be available. Please do not hesitate to call our Sales Engineers to confirm performance for your specific application needs or for the latest, next Generation Instrumentation.
