Measures static charge on surface with extreme sensitivity (down to 0.1 V at 1”). Electrostatic meter which has a chopper-stabilized (rotating) sensor with a remote sensor head at the end of a 100 cm long flexible cable. It measures down to 1/10 volt on a surface, and up to 20 000 volts (20 kV). Readings are normally done with the sensor 1″ (2.5 cm) from the surface being tested.
