With the TAC Program, TAC Star; the Model 302/001 H2S analyzer can be controlled from anywhere in the world!


Principle of Operation:

Communication:
TAC Star uses a cell modem or land-line to establish communication between the PC and the analyzer.
 

Sensor:
The Model 302/001 uses three H2S Sensors which secure the analyzer. If at any time a sensor’s output is not sufficient, the analyzer automatically removes it from the circuit and continues to function with the alternate sensors. This particular feature provides the operator with the reliability and accuracy of three analyzers in one, uniquely offered by TAC.
