Delay Electric Detonator

Delay Electric Detonators is used in a vide variety of applications. These are available in various standard wire lengths and in two different delay series (MilliSecond and Half Second). The detonators can be deployed easily and have several features that simply blast connections, field checks, and initiation. Biafo's electrical detonators feature equal timing accuracy for improved fragmentation and vibration.
-> MilliSecond detonators have standard delay numbers ranging from 1 to 20 (25ms to 500ms) with nominal time intervals of 25ms between successive delay numbers.
-> Half Second detonators have standard delay numbers ranging from 1 to 10 (500ms to 5000ms) with nominal time intervals of 500ms between successive delay numbers.
