• About Us


CHEMetrics was founded in 1969 by Gordon Rampy. Our extensive product line of water and wastewater testing kits is based on his original invention, the self-filling reagent ampoule, that allows analysts to conduct colorimetric water analysis with greatly increased simplicity, convenience, speed and safety, both on-site and in the laboratory.

We’ve grown rapidly thanks to the development of new products and applications, our novel proprietary manufacturing techniques, and the immediate acceptance of the self-filling ampoule seen in the marketplace. We also credit our employees. Their deep loyalty to each other and what we stand for makes us who we are. A number of our earlier employees are still active in the daily workings of the company.

We’re proud to manufacture and ship millions of ampoules for simplified water testing to analysts who work in the aquaculture, boiler/cooling water, chemical processing, drinking water, education, environmental testing, food and beverage, mining, petroleum refining, power generation, pulp and paper, semiconductor manufacturing, and wastewater industries.

We employ over 60 full-time personnel at our Virginia headquarters located just beyond the bustling Washington, D.C. suburbs. CHEMetrics products are available worldwide, both directly and through a global network of distributors.
