What are the types of anti-static testers?
Anti-static testers are used to evaluate ESD (electrostatic discharge) protection performance in environments such as electronics manufacturing. They mainly include comprehensive human body resistance testers (for wristbands/shoes), surface resistance testers (for mats/floors), electrostatic voltmeters (for measuring surface electrostatic potential), and ionizer testers. Common brands include FMX-003, EST series, and SL series.
Main types of anti-static testers:
1. Comprehensive Human Body Resistance Tester (ESD Shoes/Wrist Strap Tester): Tests the resistance of anti-static wrist straps and anti-static shoes/conductive shoes worn by operators to ensure conductivity between the person and the ground. Common models: SL-031, SL-033/036.
2. Surface Resistance Tester: Measures the surface resistance and grounding resistance of anti-static table mats, floor mats, conductive flooring, turnover boxes, and packaging materials. Common model: SL-030B.
3. Electrostatic Voltage/Electrostatic Field Meter: Measures the electrostatic potential (static voltage) of an object's surface to test its static elimination capability. Common model: SIMCO FMX-004 (non-contact type).
4. Ionization Test Kit: Specifically used to test the ion balance (residual voltage) and static neutralization time of ion generators such as ion blowers and ion guns.
5. Wrist Strap Monitor: Monitors the operator's wrist strap status in real time to ensure immediate grounding.
4. Grounding Monitor: Used to detect in real time whether anti-static workbenches, equipment, and the ground are effectively grounded.
Summary: Electronic factories typically use combined testing equipment (such as access control systems combined with human body testing) to ensure that the environment, personnel, and consumables all meet electrostatic protection requirements.
