The Scientific Instrument Co. Ltd. was setup in the year 1911, with the objective of providing for science laboratories in the education sector. It established very grand reputation amongst the customer worldwide popularizing as "SICO".

SICO pioneered manufacture of Resistance and Post office boxes, ovens and incubators. SICO continues to keep-up the spirit and the focus till date.

In the mid 1930s, SICO´s turnover as opportunities opened up in wider areas, particularly in electronic test and measuring, microscopy, biotechnology and geological equipments for education and research, and the new focus for Defence needs. These three sectors formed the core areas of competence ever since, and continue even today.

In the 1960s,when NATIONAL PHYSICAL LABORATORY (NPL) in Delhi identified SICO as its franchisee in the country.

NPL offered the technical know-how it developed for Microwave Test Benches to SICO for the educational sector in India with its comprehensive support and technology. SICO expanded its range of microwave products in such highly specialized field in the frequency range from 2.65 GHz to 110 Ghz covering Ku, Ka, L, S, J, C and X bands along with power supplies and instruments for measurement.

It approached Indian Institute of Technology, New Delhi for design and development of Microwave Integrated Circuit (MIC) components and have obtained technical know-how for manufacture of "Advanced Microstrip (MIC) Trainer Kit(AMTK)" and "X-Band Microstrip Antenna Trainer Kit(ATK)". AMTK was launched one and half year ago and as usual, SICO has received good number of orders from IITs, NITs, Engineering Colleges, Science PG Colleges, Polytechnics and Universities. ATK has recently been launched.

SICO,have also developed and produced very sophisticated microwave components like Hybrids, Power Dividers, Couplers, Bends, Twists, Filters, Phase Shifters, Limiters, Antennas, Amplifiers for Defence, Space, Communication, Education and Research.7 We have supplied these components to organizations such as DRDO, BEL, DEAL, HAL, ISRO, IPR, MES, Indian Navy, CAT and DOT.
