Electrostatic Field Meter with Charge Plate and ±1 kV Charger
- Part number: 61-200-0100B
Description
The PFM-711B is an accurate, portable electrostatic field meter that is easy to use and designed for one-hand operation. The PFM-711B is a digital, electronic chopper design, which allows the instrument to make electrostatic field measurements in areas where ionized air is present.
