Compact, high-speed data capture, and powerful analysis software.The EIT PowerMAP® II and LEDMAP™ are compact, all-in-one profiling radiometers that provide a comprehensive analysis of your UV source. These advanced instruments measure irradiance (W/cm²), energy density (J/cm²), irradiance profile (W/cm² as a function of time), and temperature profile (°C as a function of time), giving you a complete understanding of your UV curing process. 60% smaller than the original EIT PowerMAP and featuring increased memory, these devices offer unparalleled data gathering capabilities. Both instruments utilize EIT’s UV PowerView Software III for detailed visual and numerical analysis. EIT PowerMAP® II: For Broadband UV Sources The EIT PowerMAP® II is designed for measuring broadband (mercury) UV sources across four EIT spectral regions (UVA, UVB, UVC, and UVV). It allows you to easily compare the performance of focused and out-of-focus lamps, providing valuable insights for optimizing your curing process. (See image for visual representation). EIT LEDMAP™: For High-Speed LED Applications The EIT LEDMAP™ is specifically designed for measuring LED sources in high-speed applications. Using EIT’s patented LED L-Bands, the LEDMAP™ accurately captures the individual peaks of multiple LEDs at high speeds. (See image for example of LED peaks captured on a high-speed digital printer). Key Benefits of PowerMAP® II & LEDMAP™ Profiling Radiometers: Comprehensive UV Source Analysis: Gain a complete understanding of your UV source and its delivery to the cure surface. Identify Performance Issues: Quickly and easily identify and track the number of lamps/arrays and their individual performance, focus conditions, bulb/array uniformity, and speed/exposure time. Track System Changes: Monitor system changes over time by comparing current data with stored files. Predict Maintenance Needs: Identify maintenance needs before they impact product quality, preventing costly downtime. Optimize Curing Processes: Fine-tune your UV curing parameters for optimal results. PowerMAP® II/LEDMAP™ Features: Compact Size: 5.5” x 2.1” x 0.55” (13.8 cm x 5.3 cm x 1.27 cm) for easy use on molding lines and chill drums. Adjustable Sample Rate: User-adjustable from 128 to 2048 Hz. Large Memory Capacity: Supports 65 minutes of data collection at 2048 Hz.

UV Radiometer Explained: Your Guide to Accurate UV Measurement

UV radiometers measure the intensity and dose of ultraviolet (UV) radiation, crucial for applications from disinfection and sterilization to UV curing and safety monitoring. Learn about different types and how to choose the right one for your needs.Ultraviolet (UV) radiation is a powerful tool used in various applications, from disinfecting water and sterilizing medical equipment to curing inks and treating certain skin conditions. But how do we know how much UV energy is being emitted? That's where a UV radiometer comes in. This blog post will explain what a UV radiometer does, why it's important, and the different types available. What is a UV Radiometer? A UV radiometer is an instrument used to measure the intensity or dose of ultraviolet (UV) radiation. Think of it as a light meter specifically designed for UV light. It tells you how much UV energy is present in a given area or being emitted by a UV source. Key Terms Explained: UV Intensity (Irradiance): This measures the amount of UV power falling on a surface per unit area. It's typically measured in Watts per square centimeter (W/cm²) or milliwatts per square centimeter (mW/cm²). Think of it as the "brightness" of the UV light. UV Dose (Radiant Exposure): This measures the total amount of UV energy received by a surface over a specific period. It's calculated by multiplying the UV intensity by the exposure time. It's typically measured in Joules per square centimeter (J/cm²) or millijoules per square centimeter (mJ/cm²). Think of it as the total "amount" of UV light the surface received. What a UV Radiometer Measures: A UV radiometer can measure either UV intensity or UV dose, depending on the type of radiometer and how it's used. Some radiometers can even measure both. Why is UV Measurement Important? Accurate UV measurement is crucial for several reasons: Ensuring Effective Disinfection/Sterilization: In applications like water treatment or medical sterilization, knowing the UV dose ensures that the process is effective in killing harmful microorganisms. Too little UV light might not be sufficient, while too much could be wasteful or even damaging. Controlling UV Curing Processes: In manufacturing, UV curing is used to harden inks, coatings, and adhesives. Precise UV dose control is essential for achieving the desired product quality and consistency. Protecting People and Materials: Overexposure to UV radiation can be harmful. UV radiometers are used to monitor UV levels in workplaces and ensure that safety limits are not exceeded. They are also used to assess the UV degradation of materials. Optimizing UV System Performance: Regular UV measurements can help track the performance of UV lamps and systems, indicating when they need maintenance or replacement. Research and Development: UV radiometers are essential tools for researchers studying the effects of UV radiation on various materials and organisms. Types of UV Radiometers: UV radiometers come in various forms, each designed for specific applications: Broadband UV Radiometers: These measure UV radiation across a broad range of wavelengths. Narrowband UV Radiometers: These are designed to measure UV radiation within a…
