LFY-402D Rotating Machinery Friction Static Tester
The main purpose
Under laboratory conditions, it is used to evaluate the electrostatic
properties of fabrics or yarns and other materials after triboelectric
charging.
Instrument characteristics
1. Randomly display peak voltage, friction band voltage and time.
2. The peak voltage is automatically locked.
3. Automatically measure the decay time.
