We've been developing custom solutions to emission 
testing requirements for over 50 years!  



Richmond Instruments and Systems, Inc. (RISI) has built thousands of systems for emission test applications.
We strive to provide the most complete, trouble free, and cost effective products on the market.



Specific areas of expertise include the design and manufacture of fluid and gas handling systems, evaporative emission test cells, temperature controlled chambers and emission sampling and analysis systems.



Our engineering staff can develop custom solutions to all of your emission test cell requirements. The ability to custom fabricate many products from raw material allows our engineering staff to choose from in-house fabricated components as well as off-the-shelf components for custom integrated systems. This allows RISI to minimize end product costs and maximize quality.


We greatly appreciate the loyalty of clients such as General Motors, Chrysler Corporation, Ford Motor Company, BMW, Delphi, Honda, Toyota and many others. Many systems delivered over 25 years ago are still in service today. New systems continue to delight our customers.
