-
The anti-static wrist strap is divided into a corded wrist strap, a cordless wrist strap and a smart anti-static wrist strap. The structure is divided into a single-loop wrist strap and a double-circuit wrist strap, which is used to discharge static electricity of the human body. It consists of an elastic band, a snap button, and a spring cord. Protective resistor and plug or collet. The inner layer of the elastic band is woven with an antistatic yarn, and the outer layer is woven with ordinary yarn.

Electrostatic ring, a device that is worn on the wrist of a human body and vents the body to accumulate electrostatic charges. It is divided into a wired type and a wireless type, and has a metal ring and an elastic conductive wire mixed ring. This product belongs to the anti-static wrist strap buckle adjustment wire type, it can effectively protect the zero-resistance parts, from the interference of static electricity, to discharge the static electricity of the human body. It consists of an anti-static elastic band, a snap button, a spring cord, a protective resistor and a collet.

The inner layer of the elastic band is woven with an antistatic yarn, and the outer layer is woven with ordinary yarn. The principle of the anti-static wired wrist strap is to guide the static electricity of the human body to the earth through the wrist strap and the grounding wire. In use, the wrist strap is in contact with the skin and the ground wire is grounded directly for maximum effectiveness. Put on this anti-static wrist strap, which can safely remove static electricity generated in the human body within 0.1 seconds. The grounding wrist strap is the most basic and most commonly used in anti-static equipment.

Electrostatic ring classification and indicators:
-
-
Anti-static wrist straps are also called anti-static bracelets, bracelets, etc. Classified by grounding wire material: PVC/PU/silver plating/carbonaceous material. Classified by bracelet material: metal, dust-free silicone, rubber band. Classified by discharge mode: normal type / double circuit / corona discharge. Classified by shape: cordless / corded. Main indicator: The maximum length of the spring cord is 250cm. Leakage resistance 10^6Ω (protection resistance 10^6Ω).

Corded wristband: It is the most basic and most commonly used product in anti-static equipment. It is not only easy to set up and operate, but also the most economical. The reason is through wristband and The grounding wire discharges the static electricity from the human body to the earth. Therefore, the wristband must be in contact with the skin when it is used. The grounding wire should also be directly grounded, and the grounding wire should be unobstructed to achieve maximum effect.

Instructions for use and precautions:
-
-
1. The double-circuit PU belt is connected to one end to automatically detect the alarm device. Pull the pull switch to the "ON" position and use it.
-
-
2. Connect the grounding system with the alligator clips at both ends to form a conductive loop system.
-
-
3. Under normal good working conditions, the red indicator light and the green indicator light are not lit, and no alarm sound is emitted. When the human body is in poor contact with the tester, the red light is on and an alarm sound is sounded; when the human body is connected to the earth When the battery is bad, the green light is on and an alarm sound is sounded; when there is a poor conductive contact between the human body and the wrist band and the earth, the red light and the green light simultaneously emit an alarm sound.
-
-
4. When the battery is insufficient, the lithium battery can be replaced. The normal battery life is half a year.
-
-
5. When the surface of the human body itself is dry, the red light will be bright. At this time, the surface of the body part should be humidified to keep the static resistance of the operator normal.
