Calibration and Repair

Brookfield Instruments are known for their reliable performance, ease of use, flexibility and long lifespan.  Whether you own a Brookfield Dial Viscometer or a DV3T Touch Rheometer, we are happy to help you keep your Brookfield running at top performance to help you consistently deliver quality products always.

Our team of experienced, well-trained, certified service technicians are committed to support your service needs with an unmatched service program at our ISO certified facility in Middleboro, MA.  With every viscometer sent to our facility for service, here is how we ensure quality performance:

  3. Checking the spindles for thread wear and shaft straightness.
  4. Checking the pivot cup thumbscrew hole for wear.
  5. Checking all bearings, lube and grease as needed.
  6. If accessories are sent, they are checked for fit, wear and alignment.
  7. Set and verify calibration against an ISO certified Master Viscometer.
