Overview
This instrument is an AISRY brand ASR-7124 leather softness tester. It uses a small pneumatic control valve under load to exert force on the probe, falls at a certain speed and naturally presses the leather clamped on the test seat, and reads the leather softness index through the electronic watch on the pressure arm. This instrument is used to test the softness of leather such as footwear, furniture, and clothing.
Features
1. The load-bearing small pneumatic control valve is used to apply force, and the test process is stable.
2. The probe falls at a certain speed, and the pressing process is natural.
3. Read the softness index directly through the electronic watch on the pressure arm, and the operation is intuitive.
Principle
The instrument drives the probe through a small pneumatic control valve under load, so that it falls at a constant speed and is naturally pressed against the surface of the leather sample fixed on the test seat. The pressure depth of the probe or related mechanical parameters are measured and displayed by an electronic meter on the pressure arm, so as to obtain an index characterizing the softness of the leather.
Applications
Footwear, furniture, clothing and other leather
Standards
IULTCS IUP/36、ISO 17235-2002
Steps
1. Clamp and fix the leather sample to be tested on the test seat of the instrument.
2. Start the instrument, so that the load small pneumatic control valve drives the probe to fall at a certain speed.
3. The probe is naturally pressed against the leather sample.
4. Read and record the displayed softness index from the electronic watch on the pressure arm.
Notice
• Before use, please ensure that the instrument is placed horizontally and the test seat is stable.
• Ensure that the load is 530 +/- 10g, meeting the specifications.
When clamping a leather sample, ensure that it is flat, wrinkle-free, and firmly clamped.
• Regularly check whether the movement of the pneumatic control valve and probe is smooth and the speed is constant.
• Electronic watch readings should be clear and stable, and any abnormalities need to be calibrated or repaired.
• When the instrument is not in use, it should be properly stored to avoid dust and humid environment.
