Electrostatic Attenuation Testing machine

This instrument is suitable for testing the electrostatic properties of fibers, yarns, fabrics, carpets, decorative fabrics and other kinds of fabrics or other kinds of sheet products under laboratory conditions.
The apparatus is composed of corona discharge device and probe detector. The instrument USES a given high voltage electric field to discharge the time of the fabric and make the fabric feel static. In this way, the electrostatic charge size, the half-life of the static voltage attenuation and the static residue of static voltage are tested to show the electrostatic properties of the measured fabric.
  
Feature
 ◆ The electric charge of the fabric determines the static voltage after the high voltage discharge. On the other hand, it has to do with this static voltage. The electrostatic half-life of the fabric is an important measure of the electrostatic properties of the fabric.
◆ The instrument consists of two parts: the main engine and the computer detection system, which can be tested by the time method and the constant pressure test.
◆ The instantaneous peak value and half-life value of the high voltage discharge are shown directly by the computer system.
◆ Real-time display of voltage over time.
◆ Automatic shutdown of high voltage, automatic shutdown motor, easy to operate.
