Brief Introduction
Colourfastness to ozone for textile color fastness test fabric is mainly used for color  fastness properties exposed to ozone environment; it is the special equipment for test the  fabric colorfastness to ozone resistance feature. 

Product Description
1. Equipped with high efficiency ozone generator. It is also with HMOS sensor. When the  ozone concentration of 5ppm, control accuracy of ± 20%. At the same time with a durable  counters. When the tank is full load test, the ozone concentration can reach 5ppm in about  five minutes;
 2. Stainless steel test chamber is equipped with a large UV glass observation window, and  can be closed-loop control of the ozone concentration. Rotating the sample holder can  hold up to 24 samples. With automatic shut-off feature LED lights to improve the test  chamber observing the effect of test;
 3. In order to improve the safety performance of the device is equipped with door safety  interlock feature, the ozone decomposition catalyst and exhaust design with negative  pressure monitoring;
 4. The user can conduct on-site calibration of each year, the sensor can also be returned to  the factory for calibration. Two calibration standards have NIST traceable calibration  equipment also has periodic reminders to alert users to replace ozone decomposition  catalyst and an ozone generator.

Technical Parameter
1. The apparatus consists of an ozone generator, fans, baffles, sample holder and the  sample compartment composition, the use of high-voltage transformer ozone generator  discharge through the grid, the generator is placed before the low pressure fan, a separator  system by ozone is injected into the test warehouse, sample holder mounted on the wire  slip ring separated clip can be applied to samples of various sizes.
 2. The device is equipped with high-efficiency ozone generator, controller, closed-loop  control of ozone concentration and can accommodate 24 rotating sample holder sample by  simply setting the parameters and current parameters pre-set can be displayed on the  screen , thereby increasing the accuracy of the device can be manipulated and test results.
 Ozone chamber ozone _ for textile color fastness test steps:
 1, a control sample and a standard sample, and placed in the oven temperature (64-82F)  and a relative humidity of 67% ozone test compartment until control standard colors fade  and fade to the same standards.
 2, the experimental phase of a cycle, the cycle is repeated until the sample reaches a  predetermined color, or reaches a predetermined number of cycles.
 3, observe the degree of discoloration, to arrive at the fabric resistance to ozone color  fastness.
