One unit monitors wrist strap, worktable mat and equipment grounding at the same time.
The JHKL-10 shows the resistance of each channel in real time on a full-color LCD. When a value goes outside the set range, it sounds a buzzer and flashes a text alert on the screen. With LoRa wireless upload, the facility team can check the grounding status of the whole EPA from one control room instead of walking the line station by station.

Features
- Batch settings: alarm thresholds for all channels can be changed in one batch instead of unit by unit.
- Wide input voltage: 110 to 230 V without switching.
- LoRa upload: grounding status can be monitored centrally.
- Optional presence sensor: monitoring pauses when nobody is at the workstation, which reduces false alarms.
Where it is used
EPA (ESD protected areas), SMT / SMD lines, semiconductor packaging and test plants, cleanrooms and electronics manufacturing.
