Calibration and Certification Service

Calibration and Certification Services ensures that your instrument is operating accurately.
To ensure the quick return of your instrument, we strongly recommend you read our new procedures form.


Annual Calibration & Certification Service (C&CS) is recommended for your laboratory instruments to ensure optimum operating conditions. We can perform this service on site at your facility or you can return your instrument to our Repair Department or to any authorized Brookfield Dealer.

Our Service Department will inspect for wear perform a cleaning and adjustment of the internal mechanisms, replace pivot support and pointer shaft (if required) and straighten spindles (if required). We calibrate and certify (in writing) that your instrument is operating within proper Brookfield specifications. This certification states that your instrument has been calibrated with standards which are traceable to the National Institute of Standards and Technology (NIST). We will automatically remind you when it is time to perform the next annual Calibration & Certification Service. If your instrument has required more than an annual service in the past due in part to excessive use and/or use by multiple operators, you should consider purchasing our Ball Bearing Retrofit option for increased viscometer/rheometer durability. Your viscosity standard fluids, which should be replaced on an annual basis, can also be ordered at this time.

For Texture Analyzers, we also inspect for wear, clean, adjust and lubricate internal mechanisms, and adjust, if necessary, the zero and span for proper load cell performance. Certified calibration weights can also be purchased for your texture analyzer.

Pricing for calibration and certification services may vary depending on the instrument. Please call us for detailed pricing information.

Rental instruments are available from Brookfield at a nominal fee should you need a temporary replacement while yours is in for service. Contact Repair Customer Service for availability and pricing.


As an alternative to requesting a loan viscometer, we offer expediting services to get your instrument back to you as soon as possible. The following services are available:

One-day Service (not available for CAP and cone/plate series viscometers)
Two-day Service
Additional charges will apply; please call for details.

Rush Service Policy: Days refer to normal Brookfield operations (Monday through Friday) and exclude Saturdays, Sundays and Brookfield holidays. Service time starts from the day we receive the item for service.
