Ozone Aging Test Chamber
Category：Environmental Testing Equipment
Introduction
The Ozone Aging Chamber is a precision testing instrument designed to evaluate the ozone resistance, colorfastness, and aging performance of rubber, textiles, and other materials. By using a high-efficiency ozone generator combined with controlled airflow and a rotating specimen rack, you can simulate accelerated ozone exposure under precise temperature and humidity conditions. This allows you to quantitatively assess material durability and color retention in both low and high humidity atmospheres.
Applications
The Ozone Aging Chamber is used to test the colorfastness and aging properties of materials such as rubber, textiles, and fabrics when exposed to ozone. This instrument consists of an ozone generator, fan, baffle, specimen holder, and specimen chamber. The ozone generator utilizes a high-voltage transformer for grid discharge. The generator is positioned upstream of the low-pressure fan. The ozone generator injects ozone into the test chamber. The specimen holder features separable clamps mounted on a wire slip ring, accommodating specimens of various sizes.

FAQ
1.What materials can be tested in the Ozone Aging Chamber?
Rubber (vulcanized or thermoplastic), textiles, fabrics, and dyed materials to evaluate ozone resistance and colorfastness.
2.How is ozone generated in the chamber?
A high-voltage grid discharge in the ozone generator produces controlled ozone levels, which are then injected into the test chamber.
3.How many samples can I test simultaneously?
The rotating sample rack can accommodate up to 24 specimens per cycle.
4.Can I adjust the ozone concentration for different tests?
Yes, ozone levels are adjustable from 1 to 1000 pphm using the control unit.
5.What environmental conditions can the chamber simulate?
You can control temperature (64–82°F), relative humidity (67%), and ozone concentration to simulate low- or high-humidity aging conditions
