Measure charges on isolated conductors by direct contact using a point contact probe (sold separately). Measure charges on all types of objects by placing the charged object in a Faraday cup (sold separately), which is connected to the meter input. Two interchangeable standard sizes of Faraday cups serve most needs. The inner dimensions of these are 2-5/8” dia. x 2-¾” deep and 5-¾” dia. x 7” deep. Custom sizes are available on special order

Simple to operate
Portable, self-contained, battery operated
Two measurement ranges (20 nC and 200 nC)
