An ESZ KTTV instrument of a new, relatively simple construction has been applied to determination of electric spark sensitivity (EES) of 34 polynitro arenes and their derivatives. Results obtained are compared with those from measurements by means of older RDAD instrument. The analysis of relationship between the EES values obtained by measurements on the two instruments revealed that the relationship is not unequivocal. It is possible to come to the conclusion that the mechanisms of spark energy transfer into the reaction centre of molecule should be different in measurement on the two alternative instruments. Measurement by means of the ESZ KTTV system is more sensitive to molecular structure of the studied polynitro compounds.
