Abstract

A modular gas measuring system with a basic unit (1) with electric supply and data lines connected to it, a measuring unit (2), which is equipped with a gas sensor and with a microprocessor and is connected to the basic unit (1) by means of snap closures to form a functional unit. At least one expansion module, is accommodated by the functional unit. The modular design, of optionally accommodating different expansion modules, so that the properties and the possible applications of the gas measuring system can be expanded in a simple manner.
