Catohm NG DT300 Loop Controller
A device designed to easily measure earth resistance (in TT), monitor continuities and check installations (on standard 2P + T plugs or B.T. panels).
On its dual-colour LCD screen, the Catohm NG clearly and instantly displays the correct plug connection, as well as the earth resistance value, whose colour changes from blue to red beyond the 100 Ω limit (max. limit value set by NF C 15-100).
