EI70 Dual-Loop Grounding Monitor
EI70 dual-loop grounding monitor is mainly used to monitor the grounding of wrist straps, bench hooks and equipment on the anti-static workbench in EPA area, and is able to transfer the data regarding the grounding of such wrist straps, bench hooks and equipment to a PC via a converter for data collection. Generally, the monitor is installed on the upper right or left corner or the bottom of the anti-static workbench.
Product Features:
Apply resistive dual-loop monitoring to ensure reliable grounding of monitoring articles
Can simultaneously monitor the grounding of operator, workbench and all equipment. The bench hook monitor can be configured to monitor the equipment (the client needs to propose such request before delivery)
The data regarding the grounding of wrist straps, bench hooks and equipment monitored can be transferred to a PC via a converter to acquire monitoring data.
Sound and visual alarms
Function Description:
EI701 can monitor the grounding of 2 wrist straps, 1 bench hook and 1 set of equipment at the same time;
EI702 (EI702A) can monitor the grounding of 4 wrist straps and 1 bench hook at the same time;
EI703 can monitor the grounding of 6 wrist straps, 1 bench hook and 1 set of equipment at the same time;
EI705 can monitor the grounding of 4 sets of equipment at the same time;
EI706 can monitor the grounding of 4 bench hooks at the same time;
