The present invention relates to an automatic equipment intended for multi-reactor testing of chemical reactions, possibly in the presence of a catalyst. This equipment working under high pressure and high temperature conditions comprises a system intended for in-line analysis of the reaction products and an elaborate automation system. Fast and simultaneous evaluation of several sets of operating conditions thus allows acquisition of data on the progress of the reaction and on the performances of solid catalysts. A method and an equipment carry out measurements on an effluent resulting from a chemical reaction taking place in a reactor containing a catalyst. The method includes, in combination, injecting at least one feedstock into at least two reactors, sending the effluent coming from one of the reactors for analysis and measuring controlling the pressure and the temperature of the effluent in the circuit contained between downstream from the reactors and upstream from the analysis device, and allowing automatic monitoring and control of the chemical reaction in the reactors and of the analysis and measurement cycle performed on the effluent produced by the reaction.
