Application of Water-cooled Light Fastness Tester TF422

A Xenon Test Chamber (Weatherometer), also named Xenon Arc Weatherometer, is a water-cooled type of xenon testing chamber. This Xenon Tester measures the light fastness and aging resistance of textiles, plastics, rubber products, or materials. Besides, the weatherometer is also called a light fastness testing machine for adopting a water-cooled long-arc-xenon lamp and racking sprays to provide both light and dark cycles and natural weather conditions. Moreover, people also name it Fadeometer as its final testing purpose is to check the color fading features.

In the testing, they are under the exposure to the simulated conditions of natural weather, such as daylight, rain, temperature, humidity, etc. When the test finishes, you can get an accurate result of the light fastness. If you want to purchase a xenon tester, you can choose a Light Fastness Tester on TESTEX to test the textile’s colorfastness. We will provide a reasonable Light Fastness Tester Price.

Test Principle

Expose the specimen of the textile under specified conditions to light from a xenon arc lamp and to water spray. Meanwhile, expose the eight dyed blue wool references to light. But we also need to protect it with a sheet of window glass from water spray. Lastly, assess the light fastness by comparing the change in color of the specimen with that of the references. If the instrument is to determine the wet photosensitive textiles, no need to expose the blue wool standard. Instead, use the gray sample card to make a comparative assessment.

The Comparison of Water-cooled Light Fastness Tester and Air-cooled Light Fastness Tester 

1. Different lamp installation positions.

The lamp of the Water-cooled Light Fastness Tester is installed in the middle of the equipment in a vertical installation, and the turntable with the sample rotates around the lamp. So the distance between each sample to the lamp is equal, to ensure that each sample gets the same irradiation intensity irradiation, with good comparability. It requires cold water equipment and a pure water system and is therefore relatively expensive.

The lamp of the Air-cooled Light Fastness Tester is installed on top of the inner box of the equipment, is installed horizontally, the sample holder is installed in the middle of the inner box, and the distance between the lamp and the sample can be adjusted according to the size of the sample, its advantage is characterized by simple structure, larger test space, suitable for testing samples of different sizes. The price is relatively affordable.

2. The Air-cooled Light Fastness Tester can be moved anywhere, anytime, the machine has casters. The Water-cooled type will be installed with a water tower or chiller, which is less convenient when moving it.

3. The Air-cooled Light Fastness Tester has much more noise and will dissipate heat into the room, but the water-cooled type will take the heat away through the water.

4. Regarding the Air-cooled Light Fastness Tester, the lamp luminosity will decay after a long time of use, and about the Water-cooled Light Fastness Tester, due to a long time over water cooling, if water quality is not good, the inner wall is easy to leave residues, resulting in poor lamp translucency effect. So water quality is very important.

The test principle

The textile specimens and eight blue wool standards are sprayed and exposed to the sun in the xenon tester following the specified conditions. At the same time, cover the eight blue wool standards with glass so as to prevent spraying on the fog, and then compare the specimen with the blue wool standards for the assessment of the color fastness. If the instrument is used to determine the wet photosensitive textiles, it is not necessary to expose the blue wool standard, and instead use the gray sample card to make a comparative assessment.

Safety precautions

Note: These security measures are only for reference. They only play an auxiliary role in the testing procedure. Therefore, there is no need to follow the steps completely.

1 Do not operate the test equipment without reading and understanding the manufacturer's instructions. The operators should be responsible for following the manufacturer's instructions for safe operation.

2 The test equipment contains a light source with high brightness. So do not look directly into the light source. Close the test room door while the equipment is in operation.

3 Prior to servicing the light source, there is a thirty-minute cooling period after the lamp operation is terminated.

4 When servicing test equipment, turn off the off switch and the main power disconnect switch to ensure that the main power indicator on the machine is off when the unit is equipped.

5 It is dangerous to prolong the exposure time of the skin and eyes to fluorescent light. So do not look directly into the sun under any circumstances.


1 do not allow the machine to be moved during use.

2 place the instrument on a stable ground before use.

3 the machine must keep working under good ventilation.

4 clean the machine and keep it clean when the test is finished.

5 wipe the control box part with a piece of dry cloth rather than a wet cloth.

6 add lubricant to the mechanical part of the machine in time due to the large operation load.

7 choose the appropriate power supply voltage which should not be too high, to avoid burning the device.

Fault diagnosis and treatment

1 When there is a water shortage in the humidification tank, you need to check
whether the humidification tank is leaking and the connection is normal.
whether the humidifying water tank and water solenoid valve are working as usual.

2 The xenon water temperature becomes too high, you need to check
whether the tap water supply stops working.
whether the tap water solenoid valve is working normally.

3 Wind speed of the circulating fan becomes abnormal, you need to

open the upper right panel to check the mechanical failure of the fan.

check whether there is a connection fault in the fan motor power supply.

4 The valve switch position can not be found
open the upper panel on the back of the instrument and check whether the stepper motor is normal.
check whether the positioning screws at the opening and closing positions are loose.
check whether the ventilation valve is jammed.
