These exploder (firing units) are designed for Conformity Of Production testing and for development tests in laboratories.

Safety features include remote interlock, removable keyed enable switch and internal error checking ensuring high user safety.

Integrated 4-wire resistance measurement with pre and post testing features. Ability to set the upper/lower limits to determine what construes a resistance fault.

All our firing units / exploders versions are equipped with a high-performance square current pulse generator that regulates the energy delivered to the device to be tested.

Very short rise time (<10μ sec) without almost any overshoot. Removal of residual static electricity charges by means of discharge circuits in the firing lines.
