Testing

The Fisher 281A vacuum oven is used and reconditioned. Our technicians test ovens using a digital data logger to verify the accuracy of temperature controls and readouts. We replace any hardware or parts as is necessary and clean all ovens thoroughly prior to shipment. If it’s a vacuum oven, we typically hold them in a state of vacuum for 24 hours to ensure chamber integrity.

Additionally, if you have specific testing requirements or requests, please inform us. We will gladly work with you to ensure these requirements are addressed during testing.
