Conductivity Meter-979

A battery operated 60 KHz eddy current Conductivity Meter has been around for four decades in various forms

Measurement of absolute conductivity of electrical hardware and electrical conductors made of copper aluminium and their alloys

Overview

Conductivity meter type 979 works on the principle of Eddy Currents. It measures electrical conductivity of non ferrous metals in the range of 10% to 102% I.A.C.S. (International Annealed Copper Standard) with an accuracy of plus minus +/- 1% I.A.C.S.
The readings are taken on the spot by means of hand held probe. It has direct digital display with 0.1% I.A.C.S. as least count.
Typical user Industries: switchgear, Bus Bar, Aviation, Railway, Transformer, Cable, NF Foundries, State Electricity Board

Applications

  • Determination of homogeneity of metal near surface.
  • Estimation of properties which have correlation to electrical conductivity such as aging hardness etc
  • Useful for ingots, forging, sheets, casting, bars or finished parts of any conductive material such as aluminium, copper, brass, bronze, magnesium, lead, gold or silver.
  • To explain non destructive Ed current principal in Educational Institute

Features

  • Direct digital display with 0.1% .IA.C.S least count.
  • Accuracy of measurement is better than +/- 1%  I.A.C.S.
  • Direct reading in percent I.A.C.S even on 15 mm dia flat surface of the specimen.
  • Accurate results can be obtained even from specimen with rough surface.
  • Metal ring provided at base of probe protects the proof face from where
