About Us

Our company was founded in 1988 as Steptech Instrument Services Ltd. Aerosol filter testing and water monitoring were the two industry areas we supported with a range of instruments and services.

In the late 1990's our global development within the clean air industry led to aerosol filter testing becoming our sole focus.

In 2000 the Company was renamed DOP Solutions, to give a clear message of our intent embodied within our company name; all industry that requires filtered clean air will need a DOP solution.

The Company has operated throughout these years in Hertfordshire, in the United Kingdom . This is just North of London and easily accessible from around the UK , and close to all of the London airports, if coming from overseas.

We have sold to all parts of the world and give every customer the same loyalty for after sales support. Our UK service centre has developed over many years to support all models of instruments regardless of manufacturer and our stores holds a stock of instruments and spare parts.

Our growing reputation is now spreading through a network of overseas partners and will continue to develop onto every continent.

DOP Solutions is proud to be a leading name in aerosol filter testing and aims to maintain our strong market position through new product development and by growing our distributor network..
