In the rapidly evolving landscape of UV LED curing, accurate and reliable measurement is not just good practice—it’s foundational to achieving consistent product quality, optimizing processes, and maximizing efficiency. For manufacturers and industry professionals, choosing the correct UV measurement instrument for LED systems can significantly impact operational success. EIT offers a robust suite of LED UV radiometers, each designed with specific applications in mind. This guide will help you understand their differences and select the ideal tool for your project.
Why Precision in LED UV Measurement Matters
Unlike traditional broadband UV sources, LED UV systems offer distinct advantages, including longer lamp life, lower energy consumption, and precise spectral output. However, their unique characteristics necessitate specialized measurement tools. Accurate measurement of UV LED output ensures:
- Consistent Cure: Verifies that every product receives the correct UV dose, preventing under or over-curing.
- Process Control: Allows for monitoring and adjusting LED system performance over time, identifying degradation or issues.
- Quality Assurance: Provides quantifiable data for quality control documentation and compliance.
- Troubleshooting: Helps diagnose problems with LED arrays, power supplies, or optical delivery systems.

How to Select the Right EIT LED Instrument
Choosing the optimal EIT LED instrument hinges on your specific application needs and the level of data analysis required:
- For High-Speed Production Lines and Detailed Analysis: If your operations involve high-speed processes where comprehensive UV profiling, including temperature, is critical, the EIT LEDMAP is your go-to. Its ability to capture extensive data at high sample rates and integrate with UV PowerView Software III makes it ideal for in-depth analysis, troubleshooting, and process optimization.
- For Production Environments Needing On-Device Readings and Portability: When ease of use, portability, and quick checks on the production line are paramount, the EIT LEDCURE (Standard Version) excels. It provides immediate irradiance and energy density values, along with a basic irradiance profile, directly on the display. Its patented TMOR™ ensures accurate absolute energy measurements without complex calibration, making it highly valuable for routine checks and maintaining consistency.
- For Versatile Use (Production & Lab) with Data Analysis Capability: The EIT LEDCURE Profiler offers the best of both worlds. It functions as an easy-to-use production tool with on-device display for quick checks, but also provides the capability to transfer detailed profiling data to a computer for advanced analysis using UV PowerView Software III. This is perfect for environments that need flexibility between quick spot checks and in-depth troubleshooting or R&D.
- For Multi-Band LED Systems and Advanced Troubleshooting: If your application utilizes multiple LED wavelengths or requires comprehensive comparison of different LED arrays and their performance across various bands, the EIT LEDCURE Profiler Four Band is indispensable. This instrument provides the detailed analysis capabilities of the Profiler version but with the added advantage of measuring across four distinct LED bands, critical for complex multi-wavelength curing processes.
Practical Insights and Actionable Advice
- Understand Your LED Spectrum: Before selecting any instrument, identify the specific wavelength(s) of your UV LED system (e.g., L-365, L-385, L-395, L-405). This will determine the appropriate L-Band for your radiometer.
- Assess Process Speed: For very high-speed lines, the LEDMAP’s high sample rate is a significant advantage. For slower processes or spot checks, the LEDCURE models are highly effective.
- Evaluate Data Needs: Do you need simple irradiance/energy readings, or detailed irradiance and temperature profiles for process optimization and troubleshooting? Your answer will guide you toward a standard radiometer or a profiling one.
- Consider Future Expansion: If you anticipate working with different LED wavelengths or require more in-depth analysis later, investing in a multi-band or profiling instrument might be a more cost-effective long-term solution.
