The FMX-004 field meter is a compact electrostatic field meter used for locating and measuring static charges. Features both positive and negative polarity charges up to ±30 kV (30,000V) at a distance of 1”. Results are simultaneously shown numerically and in bar graph format on the unique multi-colored display that also displays battery charge status. The hold button allows the display to retain the static charge reading. This is especially useful where display is difficult to see during measurement. Two LED guide lights help position the field meter at the right distance from a charged test object. The conductive case and ground snap facilitate grounding for accurate measurement. The circuitry of the FMX-004 has been designed to make measurements in areas using air ionization.
