LT-JJ28 Sofa Hardness Tester

technical parameter
1. Seat loading module: 50kg diameter 200mm impact surface R341mm
2. Rear loading module: 200mmx100mm
3. Armrest loading module: diameter 50m
4. Loading capacity: 1000N
5. Hardness level: It expresses the degree of softness and hardness of a product in the range of numbers 1 to 10.
Hs=1-5 is a hard sofa (the smaller the number, the harder it is);
Hs=6-10 is a soft sofa (the larger the number, the softer it is).
6. Running speed during loading and unloading: (90 ± 5) mm/min, the system can reach any setting of 0.01-200mm/min.
7. Loading deflection curve: The relationship between the force value of the loading pad under pressure on the specimen and the corresponding indentation value.
8. Testing method:
When measuring the deflection curve during loading, even measurement conclusions should be obtained, and the loading should be increased to 1000N. Record the loading deflection curve from 0 to 1000N
Within the scope, record the loading points. Automatically generate curves within the range of 0 to 450N.
9. The hardness value (Hy) of the sofa is the average slope of the loading deflection curve at a certain point (the ratio of the loading force N to the depth of the loading point depression mm).
10. Motor: Servo motor.
11. Software system: Universal high-precision system, independently developed by Lituo, can select any point on the compression deflection curve, display the curve graph, and automatically generate reports.
12. Key components: Adopting internationally renowned brands such as servo systems, nano controlled photoelectric encoders, etc.
13. Multiple protection measures: such as various electrical protections in the power link, overload and over displacement protection in the software part, mechanical forced safety limit protection, etc.
