Nonlinear locator NR-900V is the world’s first and only nonlinear locator implementing automatic identification mode of electronic search objects against corrosion interference background.
Distinctive Features:
-
High energy potential
-
Capability to search electronic devices behind reinforcing mesh of reinforced concrete structures (main difference from compact nonlinear locators)
-
Unique identification algorithm for detected objects
-
Additional indicator on antenna system
-
GSM/DECT interference protection
-
Lightweight housing, built-in cable system
