Squib Tester – Indigenized Igniter Testing System for Aircraft Safety

Jetsys Defence presents an indigenously developed Squib Tester designed for safe testing of electro-explosive devices used in aircraft and defence systems. This advanced tester measures continuity, firing circuit integrity, and resistance values without initiating ignition, ensuring complete operator safety during maintenance and system checks.

Built for military and commercial aviation fleets, our Squib Tester provides precise diagnostics for mission-critical systems such as ejection seats, countermeasure deployment, rocket ignition sequences, fire suppression bottles, airbag triggers, and explosive bolts.

What is a Squib Tester?

A Squib Tester (also known as an Aircraft Squib Tester, Squib Igniter Tester, or Squib Firing Circuit Tester) is an ultra-safe electronic instrument used to verify the electrical health of explosive components without triggering detonation. It applies a controlled micro-current—far below the firing threshold—to measure resistance, continuity, and wiring faults.

Why Squib Testing Is Critical

Ensures ejection seats, explosive valves, and deployment systems fire correctly when needed
Prevents accidental ignition during maintenance
Detects broken wiring, incorrect harness routing, stray voltages, and degraded igniters
Prevents catastrophic aircraft or crew safety failures
Supports defence readiness and lifecycle reliability
