Electrostatic Decay Tester
The Electrostatic Decay Tester is professionally designed to evaluate the static electricity attenuation characteristics of textile and non-textile materials. It is used to measure corona discharge time, static voltage attenuation half-life, static decay curves, and other electrostatic properties.
The instrument provides quantitative analysis of electrostatic diffusibility, enabling accurate assessment of anti-static performance for research, quality control, and compliance testing.
Application
The Electrostatic Decay Tester is applicable to electrostatic performance evaluation across the following industries and products:
(1) Textile Industry: fibers, filaments, yarns, woven fabrics, knitted fabrics, nonwoven fabrics, functional textiles
(2) Apparel and Garment Industry: anti-static workwear, protective clothing, cleanroom garments, sportswear
(3) Medical and Healthcare Industry: surgical gowns, medical protective clothing, medical nonwoven materials
(4) Industrial and Technical Textiles: filter media, conveyor belts, reinforcement fabrics, industrial fabrics
(5) Electronics and Semiconductor Industry: ESD fabrics, anti-static curtains, packaging materials, cleanroom textiles
(6) Polymer and Plastic Industry: plastic films, sheets, plates, composite materials
(7) Automotive and Aerospace Industry: interior fabrics, seat materials, insulation materials, composite panels
(8) Research and Quality Inspection: laboratory test specimens, standard verification materials, R&D samples
Standards
The instrument complies with and can be applied to the following standards (including but not limited to):
(1) JIS L 1094 – Testing Methods for Electrostatic Properties of Textiles
(2) GB/T 12703 – Textiles — Evaluation of Electrostatic Properties
(3) ISO 18080 – Textiles — Test method for electrostatic properties
(4) AATCC 76 – Electrical Resistivity of Fabrics
(5) AATCC 84 – Electrical Resistance of Conductive Yarns
Features
(1) Integrated analysis and calculation unit capable of automatically computing voltage decay half-life from the static decay curve
(2) One-touch automatic measurement by connecting the analyzer and host meter
(3) Separation design of tester and controller for safe and convenient operation
(4) Digital voltmeter for direct display of test results
(5) Automatic shutdown function for high voltage and motor protection
(6) Optional data analysis software for detailed curve analysis and result reporting
(7) Stable and repeatable testing performance suitable for laboratory and industrial use
