Place the sample to be measured outside the heating plate in a temperature controlled state. One end of the sample is clamped by a clamp, and the other end is hung with a certain weight of silicon code (pre tension; if force is measured, this end must also be clamped). The sample shrinks under heating, and the dry heat shrinkage rate of the sample can be measured by the pulse signal generated by the encoder rotation driven by the friction force between the sample and the surface of the impeller; The dry heat shrinkage force of the sample can be measured through a force sensor.

1.Hot air type drying oven with long work time.
2.Come with precision balance with 1kg measuring range 200g and 0.01 accuracy.
3.Chamber materials resistant to high temperature and durable with long lifetime.

1.The sample length can be preset through the dial, and the test is accurate.
2.If it is matched with an electronic balance and a special textile printer, it can perform data processing.

1.The machine is used for reeling the cotton, man-made fiber and blending yarn to measure the show board regularity and appearance quality.

2.In order to adapt to the new standards, this instrument not only has the six new international standards of reeling density but also have an old standard of reeling density.

1. Using microcomputer control, automatic data processing, display and can be printed out.
2. The yarn holder is directly driven by the motor to rotate, can be stepless speed regulation, and the design has the function of speed measurement.
3. The CPU can automatically judge the rotation direction of the yarn holder, and automatically process the count, its indexing value is 1/10 twist.

1.Dye and color experiment
2.Segmented, dyeing levelness, penetration test
3.Temperature-gradient dyeing
4.Acidity, temperature, bath ratio difference against The dye absorption rate test
5.Concentration and other tests

1.Environmental conditions for normal operation of the test machine
2.Room temperature: 20℃±10℃.
3.Power supply voltage: 220V±22V, power supply should be reliably grounded.
4.The working environment is clean, without strong vibration source, the main engine is firmly supported, and the level of the working table (the plate surface of the lower pressure plate) is within 2/1000. 

1.Save the initial Settings when the power is off, and the test is automatically reset; 
2.Automatic measurement, intelligent judgment function, breakpoint automatic stop to save data;
3.Independent suction ventilation and heat dissipation system, suitable for long-term fatigue test internal heat;

Quantitative sampler (referred to as the raw paper quantitative sampler) is a paper, cardboard physical properties testing of special sampling equipment, with a wide range of sample size, sampling precision, easy to operate and other advantages, is the paper, packaging, testing and scientific research and other industries and departments of the ideal auxiliary test equipment.
