Abstract
We describe here a device for the autonomous use of Draeger colorimetric
sensor tubes (CSTs) at large stand-off distances (> 1 km). CSTs are an attractive
option for the detection of hazardous chemicals thanks to their high sensitivity and
simplicity but present several challenges when considered for automation. Here, these
challenges are discussed, and a proof-of-concept device that demonstrates viable
solutions is detailed. Our realized prototype is capable of processing thioether CSTs
without human interaction and demonstrates comparable sensor fidelity to manually
processed tubes.
