PR Windsor Probe™ Certified for European Safety

The Windsor Probe™ Test System for concrete compressive strength has been certified for European safety via Safenet Limited.

Chicago Illinois, October 24th, 2012 - James Instruments Inc. the worldwide leading manufacturer of non-destructive test equipment for concrete and other construction materials and coarse grained materials, has certified the Windsor Probe™ Test System for European safety. Although the system has been used safely and effectively since the 1960’s new regulations have caused minor revisions. These revisions have had no effect on the accuracy and reliability of the test system.

The Windsor HP Probe™ system rapidly and accurately determines the concrete compressive strength of a structure by driving a probe into the concrete with a known amount of force. Improved and enhanced over thirty years, this modern system is capable of measuring concrete with a maximum compressive strength of 17,000 PSI (110MPA). It has been ruggedized for use in the construction environment, yet refined to provide the user with a simpler system to operate. An electronic measuring unit has been added to help ensure proper test results which can be recorded for later review or uploading to a personal computer.

The Windsor Probe™ System features:

  • Electronic measuring system enhances accuracy and efficiency
  • Measurement to 17000 psi (110 MPa)
  • Memory for data storage and uploading to PC
  • Safe: no accidental discharge and no recoil
  • Fast and economical use
  • Determines the developing strength of concrete; improves safety, ensures quality and reduces
  • Monitors the strength for rehabilitation as concrete ages
  • Conforms to ASTM C-803 and other official tests

The Windsor Probe™ Test System has been certified to be in compliance with Directive 2006/42/EC. This certification has been made by Safenet Limited of the United Kingdom. Safenet is a European Notified Body.

“We know that receiving CE Certification for the Windsor Probe Test System has brought the time proven test method into the new millenium”, says Michael Hoag President of James Instruments Inc.
