The beginning

Polltech Instruments was incorporated in the year 1989. It was the culmination of coming together of Dr. P.K.Arora and Sharad Belekar, two highly motivated and enterprising individuals each of whom had made his mark in the field of science and technology.

Within a very short span after incorporation, Polltech Instruments was recognized as a designer, manufacturer and supplier of quality products pertaining to its chosen field of Air Pollution Monitoring instrumentation. Polltech Instruments is now recognized as pioneers in the field by the various pollution monitoring agencies. The products manufactured by Polltech Instruments are reputed to meet the most stringent requirements of compliance with national and international standards including those of US EPA and Indian Central Pollution Control Board.

Innovation and application of research-oriented expertise

Constant updation of knowledge and expertise through continuing research and development and translation of the same into innovative products has been the hallmark of the products of Polltech Instruments. The two founding partners have built upon their professional R&D expertise.

Dr. P.K.Arora, worked as a scientist in BARC, a reputed R&D organization, where he carried out pioneering research work in air (ozone) monitoring. He later went on to join a reputed organization where as Director R&D, he undertook design and development of a number of products with innovative features.

Co-founder partner Sharad Belekar holds a degree in Electronics & Telecommunication Engineering from Pune University. He worked in reputed organizations in various capacities in R&D and rose to become R&D Manager in a reputed pollution instrumentation corporate where he specialized in the design and manufacture of Gas Chromatography systems.
