ExTox plans, manufactures, installs and maintains fixed gas monitoring systems for combustible and toxic gases, addressing risks both of public safety and of personal health.  The products are designed for the commercial and industrial sector. ExTox does not produce devices for domestic use or handhelds. Apart from gas technology, our portfolio comprises extensive client support, planning of the equipment and the full range of after sales service, including regular maintenance of the equipment. With the exception of the transmitters themselves, the whole development of the product range takes place in house, including the production of hardware (mechanics and electronics) as well as software. Some components, such as the printed circuit boards or the housings, are acquired; the equipment itself, however, is always assembled exclusively at ExTox. We do not outsource any of the steps regarding the proper functioning of the product and the gas sensitivity. In recent years we focussed our development on new measuring concepts and on adjustments and additions to the basic portfolio, and to find specific solutions for every individual customer. Aspirated systems and Integral Measuring Concepts (IMC) present particularly efficient solutions to almost every measuring task, since they provide all the necessary components in one compact wall mounted housing - from sampling and preparation of measured gas, sensor technique up to the control unit. Our growth in the cooling sector led to our developing of a relatively high percentage of cooling houses appliances; yet, due to the modular structure of the ExTox approach, it is possible to use the equipment in a variety of different sectors.
