Nuclear Gauge Service

Troxler Electronic Laboratories offers state-of-the-art service using the latest technology at locations throughout the United States and Canada. In addition, Troxler distributors in over fifty countries are trained and carry parts required to complete all normal service repairs. We offer quality workmanship, fast turnaround, genuine Troxler parts, and professional, courteous service.

All Troxler Service Centers repair and service nuclear gauges.

Standard repairs include the following:

  • NIST Traceable Calibration
  • Replacement of routine maintenance items: gaskets, seals, labels, scraper ring, etc.
  • Complete electronic system analysis and adjustment
  • Mechanical and source rod inspection
  • Cleaning and lubrication
  • Leak test

Gauge Return & License Certification

A Gauge Return and License Certification form is required each time a nuclear gauge is returned to a customer. North Carolina regulations require that the customer is licensed to possess radioactive materials of the type, quantity, and form assigned to a specific gauge before returning the gauge to the customer. Complete this form to expedite the return of the gauge.
