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.

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
