High purity gas generators


Leman Instruments SAS, France


Laboratory equipment involved in the analysis of solids, liquids and gases.

Project summary

High technology start-up company in Archamps Technopole (Geneva area) needed engineering and scientific support to develop their product line. The project demanded control of various physical and chemical processes by the means of specially designed hardware and firmware. But the real challenge was to achieve high diversity of the product line at minimal production and maintenance costs. Today Leman Instruments became successful company with over 200 models in their catalog, shipping high-tech products worldwide.
