UV BOX
UV TESTER FOR UV-CONDENSATION ACCELERATION AGING TESTS
UV BOX simulates the effects of sunlight with ultraviolet rays using UV fluorescent lamps and also reproduces dew and rain using moisture condensation and water spray.
The accelerated UV aging test reproduces the damage caused by sunlight, rain and dew. In a few days or weeks of exposure of the samples inside the UV BOX, damages occurring in months or years of outdoor exposure can be reproduced.
To simulate aging due to external atmospheric agents, UV BOX subjects the materials to alternating cycles  of  UV  radiation  and  humidity  at  controlled  high  temperatures.  The  instrument  simulates  the effects of sunlight through the use of special UV fluorescent lamps and the simulation of the effect of dew and rain occurs through condensation or a spray of water (Spray option).
UV  radiation  is  responsible  for  almost  all  the  processes  of photo  degradation of  durable  materials
exposed to the external environment. The fluorescent lamps used in the UV BOX simulate critical UV short  waves  and  realistically  reproduce  the  damage  caused  by  sunlight.  The  types  of  damage  that can be simulated with the UV BOX are the following: color change, loss of gloss, chalking, cracking, cracks, blistering, veiling, brittleness, loss of strength and oxidation.
Dew is mainly responsible for most of the moisture that occurs during out door exposure, much more than rain.
The condensation system of the UV BOX realistically simulates dew and amplifies its effect through the use of high temperatures.
The  condensation  process  automatically  purifies  the  network  water  used  in  the  system.  This is because  the  process  of  evaporation  and  condensation  of  water  on  samples  is  actually  a  distillation process, which allows to remove all impurities.
UV BOX can accommodate up to 48 standard samples (75mm x 150mm) and it is possible to create special sample holders according to customer specifications.
UV lamps
UV  fluorescent  lamps  are  more  stable  than  other  types  of  lamps,  including  xenon  arc  lamps.  The spectral distribution (SPD) is not changed with the aging of the lamp, even after thousands of hours of operation, and this feature involves in more reproducible results, less frequent lamp replacements and a reduction in operating costs

Lamp s UVA-340:
UVA -340 lamps offer the best simulation of sunlight in the critical wavelength region from 365 nm up to the solar cut-off value of 295 nm.

Lamps UVB-313:
UVB-313  lamps  maximize  acceleration  through  the  use  of  the  most  aggressive  UV  short  waves compared  to those  normally  arriving  on  the  earth's  surface.
As  a  result,  for  some  materials  these lamps can produce too severe and unrealistic results
UV POWER PUCK ® II
The radiometers that first set the standard for the UV industry are 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.
UVICURE Plus II and UV Power Puck II are widely used throughout the global UV industry. With user selectable sample rates, these reliable instruments can be used for fast conveyor lines or slower lines.

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

Colorful, Easy to Read Display
Select low, medium, or high intensity for the graphical display brightness.

Operating Ranges
The UV Power Puck II instruments are 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.

Standard Features and Benefits Include:

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/cm 2 and  mJ/cm 2 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, UVV) and the introduction of EIT UVA2
EIT’s standard bandwidths - (UVA (320-390nm), UVB (280-320nm), UVC (250-260nm), UVV (395- 445nm) as well as our new  VA2  (380-410nm) bandwidth are available in the 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, & UVV.

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: mJ/cm 2 , mW/cm 2 , J/cm 2 , W/cm 2 , µJ/cm 2 , µW/cm 2

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/cm 2 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.

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/cm 2 and mW/cm 2 , and percentage.

Communications Port
