LFY-401B Electrostatic Attenuation Performance Tester

Main application
This instrument is used to test the ability of medical protective clothing materials and non-woven fabrics to eliminate the induced charges on their surfaces when subjected to a ±5000V voltage. Specifically, it measures the time it takes for the static charges to decay from the peak voltage to 10%.
Instrument features
The entire instrument is designed with a four-part modular structure:
1. ±5000V voltage control module;
2. High-voltage discharge module;
3. Random test module for decaying voltage;
4. Static decay time test module.

Technical indicators
1. The measurement range of electrostatic voltage is 0 to ±5KV.
2. The half-life time range is 0 to 99.99 hours, with an error of ±0.01 seconds.
3. The discharge time can be adjusted from 0 to 99.99 hours.
4. Sample size: 89mm × (152 ± 6)mm.
5. Working power supply: AC 220v; 50Hz.
