We started business as Jeongwo technology in 1992, and laid emphasis on allowing the user to experiment fast and conveniently by grafting the experiment facilities and measuring facilities with computer and computerizing all the data. We have imported foreign measuring device with Samdeok technology, and supplied them and managed all with our own technology since 1994. And we restarted business as Mina in 2000. Now we are developing ultramodern measuring facility and experiment facility by grafting foreign technology together.
