Color Fastness Testing

1.The inner tank is made of stainless steel, and the four corners of the inner tank are semi-circular arc transition, which is convenient for the cleaning of the studio.
2.Adopt natural convection circulation method, no noise, avoid sample volatilization during the test.
3.Adopt microcomputer P.I.D temperature controller with over-temperature deviation protection and digital display, with timing function, accurate and reliable temperature control.
4.Multi-segment programmable controller (optional)
5.Multi-segment LCD programmable controller, one-screen display of multiple parameters, and menu-type operation interface, which can simplify the complicated test process and truly realize automatic control and operation.
6.7 groups of 63 steps can be pre-programmed, each group has 9 steps, and the set time of each group is 0~5999 minutes.

1.Structural design: The box shell material is made of cold-rolled steel plate, which is environmentally friendly sprayed, and has strong corrosion resistance; the studio is made of SUS304 mirror 2.Energy-saving design: non-fluorine environmentally friendly high-efficiency refrigerant, fast cooling speed, high cooling efficiency, low power consumption.
3.Humanized design: the height of the shelf can be adjusted at will and free assembly; the outer door adopts a magnetic door seal with good airtightness; the outer door is equipped with an observation window.
4.Safety guarantee: The equipment is equipped with a leakage protection device and a buzzer alarm system.

1.Fuzzy PID controller, temperature control precision fluctuation is small, with timing function, maximum setting time is 99 hours 59 minutes.
2.The wind tunnel system of forced convection can improve temperature response speed, improve temperature uniformity and reduce temperature fluctuation.
3.Door interior has a glass door, easy to observe, when the glass door open, breeze circulation and heating automatically stop, no temperature overheat.
4.Mirror stainless steel liner, electric heating pipe heating mode, heating speed, so that uniform heating box.
5.Independent temperature limit alarm system, if the temperature exceeds the limit, the system will be automatically interrupted to ensure the safe operation of the experiment without accident.(optional)
6.Printer or RS485 interface for connecting to a printer or computer to record changes in temperature parameters.(optional)

Under the certain of pressure and within predetermined stroke, make sample rub with white cotton cloth repeatedly for specified times. By comparing the white cotton cloth after rubbed with Gray scale for assessing staining to determine colorfastness grade.

Crockmeter is used to determine colourfastness to wet and dry rubbing. Apart from textiles, also available for carpets, laminates, and printing inks, as well as the micro-scratch resistance of lacquers, coatings and painted surfaces. Motorized for frequent use and long run tests, fitted with digital electronic counter with strokes up to 9999.

To mark, print and Shrinkage ratio measurement for various textiles during shrinkage testing.

Made of high quality stainless steel, suitable for drying and dehydrating laboratory samples, such as cotton, wool, yarn and cloth samples

Crockmeter is used to determine colour fastness to wet and dry rubbing. Apart from textiles, also can be applicable for carpets, laminates, and printing inks, as well as the micro-scratch resistance of lacquers, coatings and painted surfaces. 

The friction head with standard weight makes reciprocating linear motion of standard length at standard frequency. When the set number of times is reached, the motor stops automatically.

1.Equipped with standard rubbing fabric device.
2.Adopts single chip control with adjustable speed setting.
3.LCD display, membrane panel.
4.Freely set rubbing times, available for counting up and down. Automatically alarm when setting value reached.

1.Multi range timer with end of cycle audible alarm Automatic agitator shut off. 
2.Temperature indication and control with an accuracy +/-0.25% of controller range. 
3.Display resolution 0.1 degree C.
4.System control and calibration accuracy better than +/-1 degree C.
5.Solid state relay for silent switching, reliability and zero electrical noise.
6.Push button tank drainage with inline filter to a magnetically coupled drain pump for reliability.
