Magnafield Digital UV-A Light Meter | 365nm External Sensor
High-Precision UV Intensity Monitoring for NDT Compliance
The Magnafield UV-A Light Meter is a professional-grade radiometer engineered to measure the irradiance of ultraviolet light sources used in Fluorescent Penetrant (FPI) and Magnetic Particle Inspection (MPI). Featuring a remote sensor for flexible positioning and a wide measurement range up to 20,000 cm², this tool ensures your UV-A lamps meet the strict intensity requirements mandated by international safety and quality standards.
Key Performance Features
Calibrated 365nm External Sensor: The remote sensor allows the user to measure light intensity at the exact surface of the workpiece while keeping the display unit at a comfortable viewing distance.
Wide Measurement Range: Capable of reading up to 20,000 $\mu$W/cm², accommodating high-intensity LED UV lamps used in aerospace and automotive leak detection.
Backlit LED Display: Large, easy-to-read digital display with an integrated backlight for use in the darkened booths required for fluorescent inspections.
Peak Hold Function: Allows the inspector to capture the maximum intensity reading during a scan, ensuring the most accurate assessment of a lamp's "hot spot."
Battery Life Monitoring: Features a low-battery indicator to prevent inaccurate readings caused by insufficient power during critical audits.

Standard Compliance
This meter is designed to help facilities comply with the following NDT standards:
ASTM E1417: Standard Practice for Liquid Penetrant Testing.
ASTM E1444: Standard Practice for Magnetic Particle Testing.
RRES 90061 (Rolls-Royce): Requires specific UV-A intensity minimums (typically $> 1,000$$\mu$W/cm²).
Nadcap AC7114: Audit requirements for light intensity verification.
Ideal Applications
NDT Inspection Booths: Daily verification of stationary UV lamps and handheld torches.
Aerospace Audits: Providing documented proof of light intensity for safety-critical component inspections.
Lamp Maintenance: Tracking the degradation of UV bulbs over time to determine when replacement is necessary.
Maintenance & Calibration Tip
Annual Calibration: To maintain accuracy and compliance with ISO and ASTM standards, this meter should be calibrated annually. Always ensure the sensor window is kept clean of penetrant oil or dust, as surface contamination can significantly lower intensity readings.
