Power Puck II UV Radiometer Product Summary

The Power Puck II UV Radiometer first set the standard for the UV industry and is now setting a new standard with advanced features, a colorful, easy-to-read display, multiple user-selectable modes and PC communications for data logging and trending capabilities.

The Power Puck II UV Radiometer is widely used throughout the global UV industry. With user-selectable sample rates, this reliable instrument can be used for fast conveyor lines or slower lines. It:

  • Incorporates four separate spectral response ranges and measures all four simultaneously
  • Is used in UV curing applications of inks, adhesives, soldermasks and epoxies (not for use in web press applications)
  • Display scrolls through UV dosage in J/cm2 and peak UV intensity in W/cm2 of all four separate UV spectral response ranges
  • Measures lamp performance (and possible bandwidth shift for doped lamps)
  • Compares the efficiencies of different UV curing systems
Additional Details

Easy to Use:

  • Single button for on / off and run
  • Data is simultaneously collected for up to four bands on the Power Puck II UV Radiometer, then displayed on a single screen in mW/cm2 and mJ/cm2 for quick and easy viewing by the operator.; no need to toggle through all eight readings, one screen at a time
  • Soft buttons are used for function selections and are indicated on the bottom of the display for easy operator selection and use
  • Select low, medium or high intensity for the graphical display brightness
  • Unit of measure is user-selectable to provide ease of reading for operators. Selections are: mJ/cm2, mW/cm2, J/cm2, W/cm2, µJ/cm2, µW/cm2
  • User-selectable instrument default modes for data analysis and comparison, screen and operational settings
  • In graph mode, a graph illustrating the collected UV irradiance and energy is displayed for each of the UV bands. Data is expressed in mW/cm2 time
  • USB communications port: download collected data to a computer for statistical analysis and data logging; software provided by EIT
Standard EIT Bandwidths


  • UVA (320–390nm)
  • UVB (280–320nm)
  • UVC (250–260nm)
  • Visible (395–445nm)
  • UVA2 (380–410nm)

UVA2 can be used to measure LEDs in the +/- 390nm range as well as additive (mercury-iron, mercury gallium) bulbs. UVA2 is available in a single channel Uvicure Plus II or UV Power Puck II with UVA, UVA2, UVB and visible.

Operating Ranges: The Power Puck II UV Radiometer or Uvicure Plus II instruments are now available in three operating or dynamic ranges. The standard (10W) unit works well for high-power UV curing applications. The new mid-range unit (1W) works well with lower power arc lamps and applications with lamps that are non-focused or a little further away from the cure surface. The low power unit (100 mW) works well in exposure systems and applications with low power lamps.

Operating Ranges

User Selectable Sample Rate:

  • Smooth On Data: Compatible with previous sampling rate on Power Puck versions
  • Smooth Off Data: Compatible with UV PowerMAP sampling rate at over 2000 samples per second

Reference Mode: Used for comparison between readings. Can be useful for system setup and troubleshooting. The user can store the selected UV reading in the radiometer as a baseline or reference reading, then compare that reading to another. The UV radiometer will display both readings and indicate the percentage of change between readings. Data is displayed in mJ/cm2 and mW/cm2 and percentage.

Suggested Operating Ranges

Units will turn on and display data at irradiance values much lower than the suggested operating ranges. The suggested operating ranges are where the instrument performs best.

  • High Power (Standard): UVA, UVB, Visible: 100mW/cm2–10W/cm2 / UVC: 10mW/cm2–1W/cm2
  • Mid Power: UVA, UVB, Visible: 10mW/cm2–1W/cm2 / UVC: 1mW/cm2–100mW/cm2
  • Low Power: UVA, UVB, Visible: 1mW/cm2–100mW/cm2 / UVC: 1mW/cm2–100mW/cm2
