Sivananda electronics, an iso 9001 credited company, is the manufacturer of digital conductivity meter, model: mk-iii. Portable conductivity meter has been developed to facilitate easy determination of conductivity of non-ferrous metals based on eddy current principle. Instrument uses a probe which when placed on the surface of metal indicates conductivity on a linear scale panel meter. The instrument can be used to measure stressed conditions if they can be related to the electrical conductivity of the specimen. The instrument is supplied in a rugged carrying case which gives complete protection and has separate pocket for probe. The equipment can be used without removing it from the carrying case. The other features of the digital conductivity meter are as follows:
