Static Testing Equipment
Name：LFY-401 Fabric Induction Static Tester
Details
The main purposeUnder laboratory conditions, this instrument is suitable for measuring the electrostatic properties of fibers, yarns, fabrics, carpets, decorative fabrics and other types of fabrics or various plate-shaped products. The instrument host is composed of a corona discharge device and a probe detector. Use a given high-voltage electric field to discharge the fabric for a fixed time to induce static electricity on the fabric, so as to detect the amount of static electricity, the half-life of static voltage attenuation, and the amount of static electricity remaining to show the electrostatic performance of the tested fabric.
Instrument characteristics
Whether the fabric is seriously charged is determined on the one hand by the level of the static voltage after the high voltage discharge, and on the other hand is related to the holding time of the static voltage. The electrostatic escaping speed on the fabric is expressed by the electrostatic half-life, which is an important assessment index for testing the electrostatic performance of the fabric.
The instrument is composed of a host and an automatic control box, which can be tested by the timing method and the constant voltage method respectively. The instrument uses a digital voltmeter to directly display the instantaneous peak value and half-life value of the fabric during high-voltage discharge. Automatic shutdown of high voltage and motor, easy operation.
