Welcome Message from ChemDAQ 

 
We hope that you are pleased with your ChemDAQ Steri-Trac

®

 Gas Detection System. This Gas 

Detection System has been designed and produced using state of the art facilities and we at ChemDAQ 
are very proud of this product and expect it to provide you many years of reliable service.  
 
The ChemDAQ gas monitoring system has been designed with simplicity of use as a basic design 
principle. Once installed, the system requires no maintenance beyond periodic calibration of the sensors 
and even this function has been simplified. The user will simply click out the old sensor and pop in the 
new sensor; simpler than changing a light bulb. While the ChemDAQ system is designed to be simple to 
use, it also contains all the advanced features that experienced users have come to expect in modern gas 
detection instruments 
 
While the Steri-Trac monitor can be used as a standalone instrument, the full benefit of the design is 
only achieved when the monitor is integrated into a gas monitoring system. A full gas detection system 
consists of one or more monitors connected to a ChemDAQ data acquisition system (DAQ). In addition, 
there may be one or more remote displays connected to the monitors and remote video displays where 
the results of the monitoring need to be observable at more than one location. The gas detection system 
has been designed to be modular. This approach allows the product to be tailored to each customers 
needs, and it provides for easy expansion as those needs change in the future. 
 
Our focus at ChemDAQ is customer service and we want you to know that we will work with you to 
solve any problems that may occur, though none are anticipated. We welcome praise about gas detection 
products and customer service, but we especially want to know if any problems are experienced and of 
course any suggestions for improvements to existing products or new products are most welcome.
