Nuclear Gauge Calibration and Repair Services

Humboldt maintains a complete repair and calibration facility at our Raleigh, North Carolina location. Here we provide repair and calibration services for Humboldt gauges, as well as those manufactured by Troxler and CPN. All services are performed by fully-trained and certified technicians with over 20 years of experience. Our services are built upon providing fast and reliable turn-around of your gauge calibration and repairs while maintaining competitive prices.

Calibration

Humboldt nuclear gauge calibration complies or exceeds ASTM and AASHTO standards by providing five-block calibration for all gauge calibrations. Humboldt is one of the few companies that offer five-block calibration as a standard method, most only offer 3-block. Humboldt maintains two, complete sets of calibration blocks at our Raleigh location, which are traceable to master NIST standards. These blocks are set up in isolated, temperature-controlled bays to reduce interference from other gauges in the facility affecting the calibration results of individual tests. Documentation and certificates for calibrations conform to NIST procedures and requirements.

Typical Gauge Calibration Service includes:

  • Gauge Calibration to NIST-traceable standards
  • Leak Test of Gauge
  • Complete inspection of mechanical functions of Gauge
  • Complete inspection of electronic functions of Gauge
  • Replacement of any damaged parts, as well as replacement of routine wear items, such as gaskets, seals, labels, scraper ring, etc.
  • Routine cleaning and lubrication

Repair

While in most cases, Humboldt gauges are field serviceable, Humboldt provides fast shipment of repair parts, overnight if necessary, to get your gauge back up and running. For other repairs, we maintain a complete repair department at our Raleigh, North Carolina facility. Here we maintain a large inventory of parts for Humboldt nuclear gauges, as well as parts for Troxler and CPN gauges.
