LFY-402D Rotating Machinery Friction Electrostatic Tester

Main purpose 
Under laboratory conditions, this instrument is used to evaluate the static characteristics of fabrics or yarns and other materials that have become charged through friction.
Instrument features:
1. Random display of peak voltage, friction-induced voltage and time.
2. Peak voltage is automatically locked.
3. Automatic measurement of decay time.
