Foreword 

We thank you very much for your confidence in our products and us, the ExTox Gasmess-

Systeme GmbH. 
The Control Unit ET-1D as well as all other ExTox-Products and services stand for our high 

quality targets. Our business is the health protection of mankind, protection of the environ-
ment and installations. We are glad to take this responsibility. Our Quality Management 
System therefore follows ISO 9001 and our Production Monitoring is to keep the European 

Directives 94/9/EC („ATEX“). You profit of the high reliability due to modern sensor tech-
niques and consequent interpretation acc. to the requirements of the regulations and stan-

dards valid for industrial application. 
The Control Unit of the ET-1D series is a compact and easily understandable system for sin-

gle transmitters. It is completely configurable at the control unit to be easily in line with the 
different requirements and applications. By means of its interfaces it is easy to integrate 

even in higher control and management systems. It could be used in combination with all 
ExTox Transmitters ExSens (-I) and Sens (-I).
