These chemical and biochemical products, colorimetric and inductive, ensue from the most recent developments of Choisy Laboratories Ltd. The main assets of V.M.S.® Rodian technology are the temporary colorimetric reactions that allow managers and users to instantly assess the quality of work or performance of treatments. Dead time, repair costs and training are considerably reduced. Productivity and the quality of work are thus mutually enhanced to create added value. V.M.S.® Rodian technology is an indispensable reference in the obtaining of recognized certification in hygiene, and is an instrumental component of any concerted qualitative process.
