BANDOL WHEEL ®   532

BANDOL WHEEL® 532 is a reliable accelerated weathering instrument in a compact design for acceleration of natural weathering.

BANDOL WHEEL® 532/I – designed for dry weathering cycles, was developed for quick but natural weathering, similar to outdoor exposure. To complete the weathering cycle, a mask can be added in the equipment which permits the introduction of obscurity phases without switching off the light source. The samples get a nominal UV radiation level corresponding to about “2 suns”. This permits an important acceleration in weathering that, at the same time, still correlates with natural weathering.

BANDOL WHEEL® H 532/II – designed for wet or dry weathering cycles, was developed for quick but natural weathering, similar to outdoor exposure. To complete the weathering cycle, a mask can be added in the equipment which permits the introduction of obscurity phases without switching off the light source. The samples get a nominal UV radiation level corresponding to about “2 suns”. This permits an important acceleration in weathering that, at the same time, still correlates with natural weathering.

Design and Function
BANDOL WHEEL® 532/I – designed for "Dry" weathering cycles, was developed for quick but natural weathering, similar to outdoor exposure.
BANDOL WHEEL ® H 532/II is the „Wet“ version and is based on the classical version of the equipment in which an immersion phase of the samples has been added.
To achieve this, a tank has been installed in the lower part of the test chamber. The regulation of the solution’s level in this tank allows to adjust the proportion between „Wet and Dry“ cycles from a very precise, sure and reproducible way.
To complete the weathering cycle, a mask can be added in the equipment which permits the introduction of obscurity phases without switching off the light source (increase of the lamp lifetime).





Sun vs Bandol Wheel

The average temperature homogeneity and radiation over each exposed sample are ensured by the rotation of the rack around the horizontal axis.
This leads to optimal test reproducibility and reliability.
An advantage is the exceptionally large exposition surface (more than 100 samples of 1 cm width) in relation to its size.
The BANDOL WHEEL® System,   together  with the regulation of the temperature by a micro-controller, allows to obtain results that classical instrument can not achieve.
A mean pressure mercury lamp, whose bulb is enclosed in a borosilicate shell, has  selected as the light source. The main advantages are: excellent efficiency of UV radiation (3 times more than Xenon lamps); negligible emission of UV C; balance UV A- UV B similar to the global radiation on the Earth surface; long lifetime and a very weak altering of the spectrum during the lifetime of the lamp.

The samples get a nominal UV radiation level corresponding to about “2 suns”. This permits an important acceleration in weathering that, at the same time, still correlates with natural weathering.

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.
