Power Puck® II /UviCure Plus® II

  • Post last modified:June 21, 2025

For manufacturers and industry professionals, maintaining consistent quality and optimizing processes are key to success. In UV curing applications, precise and reliable UV measurement is not just a best practice; it’s a fundamental requirement. EIT2.0 LLC, with its extensive experience since 1986 in UV measurement solutions, offers two exceptional instruments designed to meet these critical needs: the UviCure Plus II and the UV Power Puck II.

EIT’s Legacy of Excellence in UV Measurement

EIT has a long-standing history of designing, manufacturing, and supporting industrial UV measurement solutions globally. Building on previous versions, the UviCure Plus II and UV Power Puck II radiometers are engineered for ease of use, enabling professionals to establish, document, maintain, and troubleshoot process windows in diverse industrial UV curing applications.

Understanding the Instruments: UviCure Plus II vs. UV Power Puck II

While both instruments offer robust UV measurement capabilities, they cater to slightly different needs:

  • UviCure Plus II: The Single-Band Specialist The UviCure Plus II is a single-band radiometer, with the specific band (UVA, UVB, UVC, or UVV) selected at the time of order. EIT UVA (320-390 nm) is a popular choice for applications utilizing mercury bulbs. The instrument’s display provides irradiance (W/cm2) and energy density (J/cm2) values, alongside an irradiance profile.
  • UV Power Puck II: The Four-Band Comprehensive Monitor The UV Power Puck II is a four-band radiometer, monitoring EIT UVA (320-390 nm), UVB (280-320 nm), UVC (250-260 nm), and UVV (395-445 nm) simultaneously. This multi-band capability is crucial for identifying different bulb types (e.g., mercury-H, mercury-iron-D, mercury-gallium-V).A significant advantage of the Power Puck II is its ability to independently monitor wavelengths associated with surface cure (UVC) and through cure (UVA/UVV). This allows for advanced troubleshooting and process control:
    • UVC:UVA Ratio: Tracking this ratio can indicate when your reflector is becoming dirty, impacting surface cure efficiency.
    • UVA:UVV Analysis: This ratio can help determine when a mercury-gallium bulb has aged, becoming spectrally more like a standard mercury bulb.

Key Features for Enhanced Control and Analysis

Both the UviCure Plus II and UV Power Puck II offer a range of features designed for user convenience and detailed analysis:

  • Easy to Use: A single button controls unit power, data collection, and display.
  • Irradiance Graph: A visual representation of peak UV irradiance and total energy is displayed for each UV band, showing irradiance as a function of time. This graph helps visualize the number and intensity of lamps.
  • Reference Function: Users can store a run in the instrument’s memory for easy comparison with current UV conditions, facilitating consistent process monitoring.
  • Display Options:
    • Toggle (UviCure Plus II): Easily switch between graph and reference display screens.
    • All Channel (Power Puck II): Displays Joules/cm² and Watts/cm² data for all four bands (UVA, UVB, UVC, & UVV) on a single screen.
  • Setup Options: Configure instrument settings, including display mode, effective sample rate (Smooth), units (J/W,mJ/mW, or μJ/μW), and display brightness.

Smooth Modes for Tailored Data Collection

EIT instruments oversample at a very high rate, allowing users to adjust the effective sample rate for data collection. This flexibility is crucial for different application needs:

  • Smooth On: An effective sample rate of 25 Hz, matching older Power Puck units.
  • Smooth Profiler: The recommended setting for most applications, offering an effective sample rate of 128 Hz and reporting the average (RMS) peak intensity.
  • Smooth Off: A high effective sample rate of 2048 Hz, capable of detecting AC cycling in 50/60 Hz power supplies and reporting instantaneous irradiance values.

Unlocking Advanced Analysis with Profiler Versions

For in-depth analysis and troubleshooting, profiler versions of both the UviCure Plus II and UV Power Puck II are available. These versions enable the transfer of numerical data (irradiance, energy density) and the irradiance profile (Watts as a function of time) to EIT’s UV PowerView Software® III Program. This capability allows users to:

  • Analyze system changes over time.
  • Examine individual lamps.
  • Compare multi-lamp systems.
  • Troubleshoot lines effectively.
  • View lamp focus.
  • Determine lamp type.
