Description

1.Non-contact type measurement technology, not request the auxiliary grounding pole, and the installation is simple.The grounding down lead passes through the perforation of the detector directly, which will not affect the lightning protection grounding effect and the device normal working.
2.Alarm function: Setting alarm threshold (through detector panel button setting or the develop background software).
3.Equipped with an LCD screen, it can be installed and used independently.
4.RS485 communication or 4G communication realize remote real-time monitoring.
5.Explosion proof product can be used in corresponding flammable and explosive environments.
