Static Protection
(1) Human body anti-static system includes anti-static wrist straps, work clothes, caps, gloves, shoes, socks, etc.
(2) Anti-static floor includes anti-static terrazzo floor, anti-static rubber floor, PVC anti-static plastic floor, anti-static carpet, anti-static raised floor, etc.
(3) Anti-static operation series: including anti-static: I: as a table mat, anti-static packaging bag, anti-static logistics trolley, anti-static soldering iron and tools, etc.
Electrostatic measuring instrument.
(1) Electrostatic field tester: It is used to measure the surface resistance values of tabletops and floors. For plane structure and non-plane occasions, different measuring instruments should be selected.
(2) Wrist strap tester: measures whether the wrist strap is effective.
(3) Human body static tester: It is used to measure the amount of static electricity carried by the human body, the impedance between the feet of the human body, the difference in static electricity between the human body, and whether the wristband, grounding plug, work clothes, etc. are effective for protection. It can also be used as an entry discharge to isolate human body static electricity from the workshop.
(4) Megohmmeter: used to measure the impedance or resistance of all conductive, antistatic and electrostatic discharge type surfaces.
