The worldwide known SOLARBOXe light fastness testers are now available also in the RH series allowing Relative Humidity Control.

SOLARBOXe RH represent a breakthrough in small light fastness testers.
SOLARBOXe RH are the first small testing instruments allowing simulation and control
of all weathering parameters like expensive xenon instruments.
Controlled irradiance and spectrum,controlled BST temperature, controlled humidity, flooding system, are features of a top weathering equipment.
Low purchase price, low operating cost, at last an affordable and easy to use xenon weathering testing instrument offering:
− Correlation
− Acceleration
− Repeatability
− Reproducibility
of an advanced weathering test chamber.

Features:

Broad band irradiance control sensor (300-400 nm)
ensures constant irradiance for the whole life of the
lamp.
-  Controlled and monitored irradiance up to 1000 W/m2 (300-800 nm).
-  Controlled and monitored temperature at specimen tray level with BST (Black Standard Thermometer).
-  Controlled and monitored Relative Humidity. Ultrasonic humidifier ensures reliable functioning for long time.
-  Sample flooding system for cyclic sample immersion throughout your test program.
-  Microprocessor control with 4 lines LCD display.
Friendly and intuitive operating system. Free programming up to 15 different test programs.
Complete test report is produced for each test you perform simply connecting your PC to RS 232 interface: press print push button and history of test is printed.

Spectral power distribution of filtered Xenon:

A complete range of advanced UV filters are available to match sunlight conditions: direct exposure to sunlight (Outdoor); exposure through a window glass (Indoor); Outdoor and Indoor filters with IR coating to reduce infrared radiation on samples.

Description:

A strong structure is the base of SOLARBOXe RH. In the lower part two tanks are installed. The right one is for humidifier supply, the left one is for flooding system (option). Capacity of humidifier and flooding tanks ensures weeks and weeks of continuous functioning. Blinking lights on auxiliary panel inform when water
level is low.
Sample temperature depends on air flow rate in the test chamber.
BST temperature control system selects the blower speed by
means of an inverter allowing accurate speed control, subsequently we have a high accuracy in BST temperature. Relative humidity is set on auxiliary panel and displayed on
Solarbox control panel. Ultrasonic humidifier is proportionally controlled so to reach and maintain the programmed test condition. Air circulation may be modified by the user; in full closed circuit mode humidity is
obtained in extreme high range with negligible water consumption and BST is in medium high range. In partial air recirculating mode BST temperatures of lower range are possible.

Operable ranges of humidity control at various test chamber temperatures:

Green range is for fully closed air circulating circuit.
Blue range is for partially closed air circulating circuit.
Red range is for fully opened air circulating circuit
