A Rebar Cover Meter is a non-destructive instrument used to locate steel reinforcement bars embedded in concrete, measure the depth of concrete cover over the rebar, and determine rebar diameter — without cutting or coring. Minimum concrete cover is a critical structural requirement under IS 456:2000 (Plain and Reinforced Concrete Code of Practice), and rebar cover meters are widely used in structural audits, NHAI highway inspections, and NABL-accredited concrete testing labs. JS Civil Lab Solutions supplies rebar diameter and cover meters from Proceq (Profometer), Elcometer, and equivalent brands with calibration certificate, operating manual, and after-sales AMC support.

A rebar cover meter — also called a cover depth gauge or reinforcement locator — is a non-destructive testing instrument that locates steel reinforcement bars (rebar) embedded inside concrete, measures the depth of concrete cover over the bars, and estimates the rebar diameter. It uses electromagnetic principles (pulse induction or magnetic reluctance) to detect the steel without any drilling, coring, or surface damage.
Minimum concrete cover is a critical structural and durability requirement under IS 456:2000. Insufficient cover causes premature rebar corrosion, concrete spalling, and structural failure. Rebar cover meters are essential tools for structural condition assessments, NHAI quality audits, and construction quality control.
