Igniter Testers

What is an Igniter Tester?

In the aerospace, defense, and modern automotive safety industries, the initiation of many mission-critical tasks relies on ordnance and pyrotechnics. Examples include missile fuses, rocket boosters, and even life-saving airbags. The Igniter Tester, also known as a Squib Tester, is the unsung hero that ensures these ignition systems activate when they are supposed to and remain absolutely safe when they are not. 

When measuring resistance, a conventional multimeter releases a current ranging from several milliamperes (mA) to hundreds of milliamperes. While this energy may seem insignificant in everyday electronic circuits, it can easily cause a catastrophic accidental detonation when applied to a sensitive pyrotechnic initiator, such as a squib or bridgewire.

The core value of an Igniter Tester lies in its "intrinsically safe" and "fail-safe" design. Regardless of how the instrument is operated, it strictly limits the test current to the microampere (µA) or very low milliampere level.

Even in the event of an internal component breakdown or a worst-case circuit failure, the output energy will remain well below the "No-Fire Current" of the pyrotechnic device, thereby guaranteeing the absolute safety of both personnel and equipment.
