product description:

According to the ANSI/ESDS20.20 section of the guidelines for personnel grounding, “In all cases, the personnel grounding system includes people, control objects and the connection to the grounding point. The record sheet should be kept to verify that the personnel have tested their "Personal grounding device", and ESD-S1.1 Section 6.1.3 states that "when the continuous monitoring system is used, the daily (wrist strap system) test can be ignored".

The SDW1801D-II wristband online monitor can continuously monitor the working status of an operator's wristband grounding system. Automatic sound and light alarm prompts the operator to check the bad grounding system and components, eliminating the costly and cumbersome wristband inspection record keeping need. The product has the advantages of small size, light weight, simple use, strong real-time monitoring and intelligent judgment of high-performance MCU, which can provide reliable guarantee for the normal use of the wrist strap grounding system in the anti-static (personal) work area.
