UV Power Puck II

Uvitron UV Power Puck II Radiometer
  • Incorporates four separate spectral response ranges and measures all four simultaneously
  • Used in curing applications of inks, adhesives, soldermasks, and epoxies (not for use in web press applications)
  • Display scrolls through UV dosage in Joules/cm2 and peak UV intensity in Watts/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
Uvitron UV Power Puck II Radiometer

Product Summary

The radiometer that first set the standard for the UV industry is now setting a new standard with advanced features and an easy to read display, multiple user selectable modes, and PC communications for data logging and trending capabilities.

Power Puck II 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.

Easy to Use - Single Button for On/Off and Run

UV Data Displayed on One Screen for Up to 4 Bands

Data is simultaneously collected for up to 4 bands on the UV Power Puck II, 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.

Standard EIT Bandwidths (UVA, UVB, UVC, Visible) and the introduction of EIT UVA2

EIT’s standard bandwidths - (UVA (320-390nm), UVB (280-320nm), UVC (250-260nm), Visible (395-445nm) as well as our new UVA2 (380-410nm) bandwidth are available in the Uvicure Plus II and UV Power Puck II. 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, & Visible.

UV Power Puck II operating ranges

Operating Ranges

The UV Power Puck II is now available in three operating or dynamic ranges. The standard (10 Watt) unit works well for high power curing applications. The new Mid Range unit (1 Watt) 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.

Setup Function

Provides user selectable instrument default modes for data analysis and comparison, screen, and operational settings.

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 vs. time.

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.

UV Power Puck II reference mode

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 base line or reference reading, then compare that reading to another. The radiometer will display both readings and indicate the percentage of change between readings. Data is displayed in mJ/cm2 and mW/cm2, and percentage.

Unit of Measure

The unit of measure is user selectable to provide ease of reading for operators. Display the data as you want to see it. Selections are: J/cm2, mW/cm2, J/cm2, W/cm2, µJ/cm2, µW/cm2

Colorful, Easy to Read Display

Select low, medium, or high intensity for the graphical display brightness.

Suggested Operating Ranges
(Standard) High Power: UVA, UVB, Visible: 100mW/cm2 to 10W/cm2 / UVC: 10mW/cm2 to 1W/cm2
Mid Power: UVA, UVB, Visible: 10mW/cm2 to 1W/cm2 / UVC: 1mW/cm2 to 100mW/cm2
Low Power: UVA, UVB, Visible: 1mW/cm2 to 100mW/cm2 / UVC: 1mW/cm2 to 100mW/cm2
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.
