The QUV accelerated weathering tester reproduces the damage caused by natural sunlight, rain, and dew. In a few days or weeks, the QUV tester can reproduce the damage that occurs over months or years outdoors. To simulate outdoor weathering, the QUV accelerated weathering tester exposes materials to alternating cycles of ultraviolet (UV) light and moisture at controlled, elevated temperatures. It simulates the effects of natural sunlight and artificial irradiance using special fluorescent UV lamps in the UVA, UVB, and UVC portions of the spectrum. It simulates dew and rain with condensing humidity and/or water spray.

The QCT condensation tester – “The Original Cleveland Cabinet™” - was first introduced in 1956. The QCT simulates the damaging effects of outdoor moisture attack by condensing warm water directly onto test specimens. In a few days or weeks, the QCT tester can reproduce the damage due to moisture that occurs over months or years outdoors. The QCT tester is fast, easy to use, and affordable. It uses 100% condensing humidity to simulate and accelerate damage caused by rain and dew on metals, paints, and organic materials. This degradation is accelerated relative to natural exposures by increasing moisture temperature. The QCT tester replaces water immersion and ordinary (non-condensing) humidity tests. The QCT condensation tester is used in thousands of labs in over 50 countries. It is the simplest, most reliable, and easiest-to-use condensation tester available.

Q-RACK outdoor exposure racks are the same aluminum racks that are used at Q-Lab Florida and Q-Lab Arizona to perform natural outdoor exposure tests. Now you can buy these professional-quality racks to perform exposures at your own site. Q-RACK kits, accessories, and non-standard mounting systems are available for different applications and testing requirements. They meet ISO, ASTM, SAE, and other international standards for outdoor testing. The Q-RACK frame may be positioned at 0°, 5°, 45°, or 90° from horizontal. The durable Q-RACK design has been proven over decades of harsh subtropical and desert exposures. The racks are versatile, dependable, and affordable, and come in kit form for easy assembly.

The Universal Calibrator (UC) system is used for calibration of temperature in Q-SUN xenon arc testers and irradiance in QUV accelerated weathering and Q-SUN testers. This system consists of irradiance and temperature "smart sensors" that can be used to calibrate all new Q-Lab testers. All smart sensors are affordably replaced or recalibrated yearly. A handheld display unit is available that can be used to calibrate older testers, using the same UC smart sensors. Q-Lab also fully services and supports existing, legacy calibration radiometers and thermometers. Download our Universal Calibrator brochure for more information on the UC system.

Cyclic corrosion testing provides the best possible laboratory simulation of natural atmospheric corrosion. Research indicates that test results are similar to those obtained outdoors in resulting structure, morphology, and relative corrosion rates. Q-FOG CRH cyclic corrosion chambers can perform traditional salt spray, Prohesion, and nearly all cyclic automotive tests. They feature fully-adjustable relative humidity and precise control over ramp times. An optional shower function is also available in center-mounted stationary or overhead (top-mounted) swaying configuration. Rapid Ramp Heater capability enables performance of automotive corrosion tests that have very fast transition times. Q-FOG chambers are available in two sizes to fulfill a wide range of testing requirements. Q-FOG cyclic corrosion testers are the simplest, most reliable, and easiest-to-use corrosion testers available.

Cyclic corrosion testing provides the best possible laboratory simulation of natural atmospheric corrosion. Research indicates that test results are similar to those obtained outdoors in resulting structure, morphology, and relative corrosion rates. Q-FOG SSP model testers from Q-Lab can run traditional salt spray and Prohesion tests. Q-FOG CCT testers can also perform wet/dry cycling with saturating humidity. Q-FOG chambers are available in two sizes to fulfill a wide range of testing requirements. Q-FOG cyclic corrosion testers are the simplest, most reliable, and easiest-to-use corrosion testers available.

For over 60 years, Q-PANEL test substrates have been recognized as the world standard for a consistent and uniform test surface for paints, plating, adhesives, sealants, rust inhibitors, and other coatings. This consistency and uniformity is now available through Q-Lab’s CX-series corrosion test coupons. Q-PANEL corrosion test coupons ensure repeatability and reproducibility when performing laboratory corrosion testing. They help a user independently monitor the test conditions in the chamber, by measuring the mass loss of the coupons as the test progresses.

Q-PANEL® steel test substrates from Q-Lab minimize metal variability as a source of bias in critical tests. Made from standard low-carbon, cold-rolled steel, they are clean, consistent, convenient, and economical. A wide range of panel sizes and types are available for immediate shipment from stock. Panels are stored completely clean and, in most cases, can be used right out of the box.

Q-PANEL Aluminum test substrates from Q-Lab minimize metal variability as a source of bias in critical tests. Made from widely-available aluminum alloys, they are clean, consistent, convenient and economical. A wide range of panel sizes and types are available for immediate shipment from stock. Panels are stored completely clean and, in most cases, can be used right out of the box.
