Tabletop Xenon Test Chambers

The sun you have always wanted: sunshine day and night for accelerated light stability and weathering tests

Radiant energy in the SOLARBOX is provided by a single superior air-cooled Xenon Lamp generating an irradiance level up to two times that of the sun. Irradiance is the rate at which light energy falls onto the samples. A weathering tester must control irradiance if it is to achieve accurate and reproducible test results.

SOLARBOX offers constant measurement and control of irradiance during every test, compensating for lamp and UV filter aging via a closed-loop irradiance narrow-band sensor control system. Irradiation uniformity is guaranteed by a parabolic reflector chamber with the Xenon Lamp in the focus, the best design for a reliable flat-bed xenon exposure system, and very good agreement with rotating drum xenon exposures.

Temperature Control

Temperature is another component of the end-use environment that plays a key role in material degradation. Heat in the natural environment comes from the infrared portion of natural sunlight.

An object exposed to direct sunlight is always warmer than the air surrounding it. Your product is exposed in the same manner in our SOLARBOX tester.

The radiant heat received from the Xenon Lamp is continuously monitored and controlled by a B.S.T. (Black Standard Thermometer) built in the plane of test panels near your samples.

In SOLARBOX 1500e and 3000e there is the control and display of the black standard temperature between 35°C and 100°C. The importance of temperature in the weathering degradation process is that the kinetic reaction rate doubles for every 10°C temperature increase.

Consequently, because the temperature produces accelerated ageing, it is essential to be able to control of B.S.T. during exposure to filtered Xenon radiation.

Simulating the effect of the rain and moisture

A flooding system for conducting weathering tests with freely selectable flooding intervals is an available option for SOLARBOX 1500e and 3000e:

• water level indicator
• continuous flooding possible
• flooding intervals selectable between 1 and 999 minutes throughout the test program
• water temperature of 30°C to 50°C.

During flooding, the Xenon Lamp can be programmed on or off.

The flooding system operates with demineralized water from a closed recycling circuit so to minimize the need of demineralized water but offers the same test results as a high-consumption spray system. PVC and corrosion-resistant materials ensure the long life of this tank pump system: a capacity up to 50 liters.

Xenon Lamp and UV Filters Combination Optimize Sunlight Simulation

The available OPTICAL CUT-ON FILTERS limiting radiation of xenon lamp are:

• Soda-lime glass UV filter, extra long life, to simulate outdoor exposure.
• Soda-lime glass UV filter, extra long life, to simulate indoor exposure.
• Soda-lime glass UV filter, extra long life, to simulate outdoor exposure with Infra Red reflection coating.
• Soda-lime glass UV filter, extra long life, to simulate indoor exposure with Infra Red reflection coating.
• Dedicated UV filter especially tailored for specifications on request.

Test Report 

With SOLARBOX 1500e and 3000e the test conditions and all the parameters are periodically saved in a PC or sent to a printer through a RS 232 serial interface: a simple but powerful tool that fully documents the test.

Radiometer and Black Panel Standard Thermometer

The UV MULTIMETER is a battery-operated radiometer and thermometer, specially developed for use with the SOLARBOX, but it can control the output of any UV Lamp in many industrial applications.

It is portable and together with its case, can easily be returned to the manufacturer for re-certification of calibration to an official national laboratory standard.

The UV MULTIMETER measures either irradiance or temperature using the following easily interchangeable, good cosine response sensor:

• UV 295 - 400 NM large band sensor
• UV 340 NM narrow band sensor
• UV 420 NM narrow band sensor
• Illuminance sensor spectral response similar C.I.E. photopic luminosity curve. Measuring range up to 2 MEGALUX.
• Black Standard Temperature sensor.
