Find Frequently Asked Questions and Answers about Radiometer Recalibration

Regular recalibration ensures your UV radiometer maintains accuracy and reliability over time. ASTM recommends 6-month calibration cycles for all radiometers to ensure your measurements remain precise and compliant with industry standards.

We service ALL brands of UV radiometers and light meters, not just Spectro-UV equipment. Our expertise extends across the industry. For all non-Spectro-UV Radiometers, only a PASS/FAIL option is available.

We offer an industry-leading 3 business day turnaround after we receive your equipment. This ensures minimal downtime for your operations.

Yes! Spectro-UV has been an ISO/IEC 17025 Accredited and ANSI/NCSL Z450-1 Facility since 2018. Our factory-trained technicians are ISO-certified and perform all calibrations in temperature and humidity-controlled environments per ISO standards.

We offer three service levels to meet different needs and budgets:

ISO 17025 Calibration - Our highest tier, providing metrological certainty with formally stated measurement uncertainties, complete before/after data, and full accredited certification.

Standard OEM Calibration - Full factory calibration to Spectro-UV specifications, NIST/ANSI Z540-1 traceable, with detailed certificates and before/after data.

PASS/FAIL Recertification - Cost-effective verification confirming operational status and compliance with factory tolerances (available for any brand UV Radiometer w/applicable sensor).

ISO 17025 includes:

• Formal accredited certificate with measurement uncertainties
• Complete before/after data documentation
• Performance restoration adjustments
• Factory repair/replacement of worn parts (for Spectro-UV units) if required*
• Full ANSI/NCSL Z540-1 and NIST compliance
• Dated calibration label
• Comprehensive decontamination

Standard OEM includes:

• NIST/ANSI Z540-1 traceable certificate with before/after data
• Performance restoration adjustments
• Factory repair/replacement of worn parts (for Spectro-UV units) if required*
• Dated calibration label
• Comprehensive decontamination

PASS/FAIL includes:

• Formal PASS/FAIL certificate
• Function check and operational verification
• Optional adjustment for Spectro-UV units (additional fee)
• Dated recertification label
• Comprehensive decontamination

*Excludes damage from willful abuse or neglect. Subject to part availability for discontinued models.

Follow our simple 4-step process:

1. Contact Us - Complete the Recalibration Request form on our website to obtain an RMA number (valid for 30 days)
2. Prepare Your Equipment - Decontaminate per your Operator's Manual, bag all components, and return all sensors and readout units together
3. Calibration - We'll calibrate your equipment within 3 business days of receipt. Expedited options are available.
4. Receive & Document - Get your equipment back with full certification and documentation

Yes, decontamination is required. You must decontaminate all components per your Operator's Manual and bag them to prevent recontamination. Failure to properly decontaminate may result in rejection or additional charges.

Return all sensors and readout units together as a complete system. Make sure everything is properly decontaminated and bagged.

Each radiometer undergoes a comprehensive inspection and decontamination upon arrival. Our technicians then meticulously test each device's operational capabilities against Spectro-UV's rigorous standards before performing precision calibration testing.

Yes! For Spectro-UV radiometers, all repairs related to normal wear and tear are performed at no additional cost during ISO 17025 and Standard OEM calibration services. This is subject to part availability for discontinued models. Damage from willful abuse or neglect is excluded.

During ISO 17025 and Standard OEM calibration, we make adjustments to restore your instrument to its original manufacturing specifications. For PASS/FAIL recertification, if a Spectro-UV radiometer doesn't meet specifications, adjustments are available at an additional fee.

We adhere to multiple international standards:

• ISO/IEC 17025 (for our highest tier service)
• ANSI/NCSL Z540-1
• NIST traceability
• ASTM recommendations for 6-month calibration cycles

ASTM recommends 6-month calibration cycles for all radiometers. We also offer 12-month cycles upon request based on your specific operational needs.

Yes! Depending on your service level, you'll receive:

• Formal accredited or traceable calibration certificates
• Before and after calibration data (ISO 17025 and Standard OEM)
• PASS/FAIL certification (Recertification service)
• Dated calibration or recertification label affixed to your device

Measurement uncertainty is a formal statement of the possible range of error in a measurement. It's included in ISO 17025 calibration and is essential for detailed process impact and risk analysis in quality-critical applications.

Your RMA number is valid for 30 days from issuance.

For an additional $200/per unit, we do offer expedited calibrations to where once an item is received in our facility, that we will do a complete calibration and ship the following business day (24 hour turnaround time/next business day)

All calibrations are performed in our temperature and humidity-controlled environments per ISO standards at our ISO/IEC 17025 Accredited facility.

We service discontinued models subject to part availability. Our technicians will evaluate your equipment and inform you of any limitations.
