The TERRALIGHT ground monitoring system is designed for use when filling or discharging potentially explosive materials.

The system effectively eliminates any static charges. This system monitors the connection to the bonding conductor and the contact across the ground clamps. TERRALIGHT is designed for connecting one ground clamp or a cable rewinder fitted with ground clamp.

Can be used in:
Zones: 1, 2, 21, 22.
