The QCT condensation tester 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.
Fast and versatile
The QCT tester can be used to:
- Screen paints for blister resistance over a weekend at 55 °C
- Evaluate oil-based rust inhibitors in less than 120 hours at 38 °C
- Rate effectiveness of mill-applied oils in only a day
- Test surface reactivity of cold-rolled and galvanized steel in hours
- Test wood finishes for blistering, moisture and mold resistance
