With regular maintenance, service and calibration, you can ensure your instruments run smoother for longer, and achieve the most reliable and accurate results.
Prescott Instruments can service and calibrate a range of laboratory equipment in line with our ISO 17025:2017 accreditation. Not limited to only Prescott Instruments products, the highly skilled service engineers at Prescott Instruments are also able to service and calibrate most rubber testing equipment, alongside general material testing instruments.
We can service and calibrate your instruments and equipment on demand. Support, service and calibration are available for:
- Prescott Instruments: All instruments and products
- Alpha and Monsanto: Rheometers, Mooney Viscometers, Tensile Testers and associated equipment
- Negretti: Mooney Viscometer
- Wallace: Hardness, temperature and density
- Other: Tensile Tester and load cell calibration
The calibration of force testing equipment can be performed in accordance with our A2LA accreditation both in-house and at customer sites.
All of our calibration procedures conform to our ISO9001:2015 certification and all calibrations are traceable to national standards. We are also the world’s first company to statically calibrate torque standards, whereby ISO 17025:2017 is used as a transfer system for dynamic calibration, providing traceability to BS7882:2008.
We also possess ISO/IEC 17025:2017 and ANS/NCSL Z540-1-1994 accreditations for both tensile and compressive forces.
The range of tensile testing equipment varies greatly from industry to industry, but Prescott Instruments can cater for all types of equipment in the rubber, plastics and elastomers industry within the following ranges:
- Tension from 1N to 200kN
- Compression from 1N to 200kN
Individual load cells can also be calibrated along with special purpose test rigs and load system in tension and compression. We can also offer verification of many types of extensometer, including mechanical, laser and optical systems.
Including leading manufacturers such as:
- Alpha Technologies
