FMX-004 Electrostatic Fieldmeter
The FMX-004 is a compact handheld electrostatic fieldmeter designed for accurate measurement and source of static charges in industrial environments. Its pocket-sized format, lightweight construction, and intuitive push-button interface ensure easy operation even in demanding production or maintenance conditions. The device measures both positive and negative electrostatic fields within a range of 0 to ±30 kV at a standardized distance of 1 inch (25 mm), supported by integrated LED indicators that ensure correct measuring distance and repeatability. Results are simultaneously displayed on a clear LCD screen using both numeric values and a color-coded bar graph, providing immediate visual interpretation of polarity and intensity.The FMX-004 features automatic range switching, enabling seamless transitions between low and high measurement ranges. Additional functions include zero adjustment, hold mode for data retention, and ion balance measurement capability up to ±300 V. An automatic power-off function optimizes battery life, while battery status indication ensures operational reliability. Engineered with a conductive housing and grounding connection, the FMX-004 guarantees improved measurement accuracy in environments affected by electrostatic discharge or ionization. Its fast response time and stable readings make it suitable for quality control, electronics manufacturing, semiconductor processing, and other static-sensitive applications. Optional analog output accessories allow continuous monitoring and integration with external data acquisition systems such as PLCs, chart recorders, or data loggers, extending its functionality for process control and analysis. Robust, precise, and easy to use, the FMX-004 is a reliable instrument for professional electrostatic field measurement and static control diagnostics.
