LFY-423 Anti-static Performance Tester

Main purpose 
Suitable for the determination of the anti-static performance of anti-static fabrics. 
Principle of the Experiment 
The standard cloth is wound onto the friction rod and rubs against the sample. This causes the sample to become charged. The friction rod rubs the sample three times at a speed of 2 seconds per time. Then, the friction rod is lifted away from the sample. The potential value and peak potential value of the sample when it decays for 0.5 seconds are detected by the detection device, and this is used to evaluate the anti-static performance of the sample.

Instrument characteristics 
1. It is mainly composed of two parts: the mechanical box and the control box. The mechanical box consists of a friction device and a detection device. 
2. The peak voltage and half-life voltage of the sample are displayed in real time using liquid crystal. The friction device is automatically controlled, which is easy to operate, stable and reliable.
