The AD-1684A is an electrostatic field meter designed for detecting the existence of static electricity
The AD-1684A can be used for measuring the electrostatic charge of measured objects or on automated factory lines, and for confirming the effect of a static eliminator (e.g. the AD-1683).
Compact and light body
Large, easy-to-read LCD
Amount of the electrostatic charge is displayed as a bar graph
Hold function
Possible to measure the ion balance of a static elimination device
