Wristband alarm real – time monitoring of the operator’s wearing of electrostatic wrist strap and ground wire access to the ground, in case of abnormality the status automatically alerts immediately. Suitable for most of the anti-static wrist band. Esd wrist straps monitor microcomputer chip control, debugging – free, plug and play, easy to use and can correctly judge the contact between the ground wire on the ground and the ground wire on the workbench. Test parameters can be set as required, generally 1.068 – 2.0 mq, conforming to the specifications, or set monitoring parameters freely. The sensitivity is high, and the monitor will give an alarm when the electrostatic discharge path fails for 0.1 seconds or more. Good reliability and strong anti-interference ability. Anti static monitor use high precision electronic components and the America half original chips have high stability, with the safety certificate power source,through a number of certification.
