Static Testing Equipment
Name：LFY-402A fabric friction electrostatic tester (computer control)
Details
The main purposeUnder laboratory conditions, it is used to evaluate the electrostatic characteristics of fabrics or yarns and other materials charged by friction.
Instrument characteristics
1. Using advanced numerical control technology and rotating wheel friction electrostatic testing method, it can automatically determine the static voltage half-life value and static voltage half-life time. The use of high-precision electrostatic sensor amplifiers improves the test accuracy and the operation is safe and reliable.
2. The instrument is composed of a testing machine and a computer detection system. The static attenuation ratio is adjustable, which broadens the test range.
3. The test probe adopts the positioning block limit design, which is convenient for positioning.
Technical index
