Humboldt calibration and repair

A2LA-Accredited Calibration Services

Humboldt maintains a complete ISO/IEC 17025:2017 accredited repair and calibration service at each of our locations. Each calibration includes a complete inspection and documentation of the device prior to calibration. First the device is disassembled and/or cleaned, inspected, lubed if required, parts are replaced if necessary, and then calibrated. All calibrations are performed on certified, calibration devices and the customer is provided with a certificate documenting the calibration.

Nuclear Gauge

Full-Service Nuclear Gauge Calibration

To support our customers and their use of our nuclear gauges, Humboldt maintains a complete ISO/IEC 17025: 2017 accredited repair and calibration facility at Humboldt Scientific in Raleigh, North Carolina. Here we provide repair and calibration services for Humboldt gauges, as well as those of the other manufacturers. All services are performed by experienced and certified technicians combined with over 25 years of experience. Our services are built upon providing fast and reliable turn-around of your gauge calibration and repairs while maintaining competitive prices. Humboldt nuclear gauge calibration complies or exceeds ASTM and AASHTO standards by providing five-block calibration for all gauge calibrations. We maintain multiple sets of calibration blocks, which are traceable to master NIST standards.

These blocks are set up in isolated, temperature-controlled bays to reduce interference during calibration. Documentation and certificates for calibrations conform to NIST procedures and requirements.

We also provide leak test analysis services, gauge rental and disposal services.
