Company Company

Emco Electronics established in 1973 initially as an R&D outfit progressively grew into a full fledged manufacturing and marketing organisation. It started off by manufacturing Test Measurement & Control devices & Instruments which activity has today become our company’s CORE COMPETENCY. In fact, the CORE strength accumulated by the company over last so many years has enabled EMCO ELECTRONICS to enter into new lines of business like agency activity & establishment of PCB’s Test & Repair Center. Emco Electronics is an ISO 9001:2008 certified Company. The Factory is located at Vasai (Thane Dist.) with Head Office at Lower Parel (Mumbai). A Branch office at Bangalore enhances sales & service support to the Southern Region.
