LFY-403C Automatic Friction Charge Quantity Tester

Main application
The LFY-403C automatic friction charge quantity tester uses mechanical devices to replace the manual friction charging method for testing the surface charge density of static electricity on textiles, avoiding the influence on the test results due to inconsistent manual friction pressure.

Technical indicators
1. Friction rod friction speed: 1 times per second (friction speed adjustable);
2. Number of friction cycles: 1 to 999 cycles can be set arbitrarily;
3. The friction rod is mechanically driven to move in one direction, and automatically lifts back during the return stroke;
4. The material of the friction rod is hard vinyl tubing. Outer diameter: (32 ± 0.2) mm, thickness: (3.1 ± 0.2) mm, length: (400 ± 1) mm;
5. Friction force: 40N (weight 4.08kg);
6. Effective friction distance: 250mm;
7. Base plate: Wooden, 320mm × 450mm;
8. Insulation rod material: Acrylic resin. Diameter: 20mm, length: 500mm;
9. Charge quantity measurement range: 0 to ±9.999μC, measurement accuracy: ±0.001μC
