This tester has a full-scale range of 10 Ω but has the same accuracy as our other testers’ 2 Ω range. The higher full-scale range of the 101-SQB-SG adds the versatility needed to measure more circuit paths in your test articles while improved accuracy and resolution gives the tester superior performance when measuring both single and parallel squib configurations.

A high-performance analog front end connects to a precision 24-bit ADC while digital filtering and calibration allow for unparalleled reading stability during measurements. Measurements are displayed on a 3.2-inch backlit transflective LCD allowing for readability in both extremely dark and bright conditions.

A single 6-pin Mil-Spec circular connector is utilized for test leads and battery charger jack, making it physically impossible to simultaneously connect the AC/DC Charger while measuring with the test leads. After a full charge, you can expect over 24 hours of accurate meter operation.

Stand-alone squib testers that can be integrated into multi-channel testers.

Designed for testing squibs and other electrically detonated ordnance, Space Electronics 101-SQB-RAK and 101-SQB-BTP fail-safe squib testers can test diodes and measure resistances with great accuracy while dramatically reducing the risks of accidental detonations because of their built-in fail-safe modules.

Our squib testers are specialized fail-safe electronic testers that measure components of electro-explosive circuits, using a test current which is a 1000 times less than a conventional precision low resistance tester.

This squib tester can be used as a stand-alone tester or they can be integrated into multi-channel squib testers by connecting them to a front-end switching matrix. Please note that Space Electronics also offers multi-channel testers.

These fully automated igniter testers are used to test devices such as rocket igniters, fuses, explosive bolts, squibs, blasting caps, bit test lines, and electro component lines (relays, actuators, diodes, semiconductor devices) that are contained in the weapon. Our SQB Series squib igniter testers dramatically reduces the risks of accidental detonations without compromising high accuracy.

• OEM Subassembly Level Testing – Verify the electrical integrity of weapon subassembly components before they are integrated into the weapon system.
• OEM System Level Testing – Perform weapon-level electrical integrity testing before delivery to the customer.
• Field Level Testing – Conduct field or depot-level electrical integrity tests before troop deployment or integration with a launch platform.
