Differences between FMX-003 and FMX-004 Testers
The FMX-004 is an upgraded replacement for the FMX-003. The main differences are: the FMX-004 has a larger measurement range, adds a high-voltage continuous measurement mode, ion balance measurement plate detection, and clearer distance LED indicators, and features better measurement accuracy and an anti-static housing.
Measuring Range:
FMX-003: Measurement range is 20KV.
FMX-004: Measurement range increased to 30KV.
Functional Upgrades:
The FMX-004 is equipped with a dedicated ion balance measurement plate for measuring ion balance within a certain range, while the FMX-003 has fewer functions.
Indicator Lights and Accuracy:
The FMX-004 uses two LEDs to ensure an accurate measurement distance of 25mm, resulting in more precise measurements.
Housing Material:
The FMX-004 uses a more advanced conductive material for its housing, providing better electrostatic protection and preventing it from becoming a static source.
