With a maximum testing current of 50mA, the BCT-5-series Bridgewire Continuity Tester is precisely engineered to safely and haptically indicate a complete bridgewire circuit. Simply stated, it’s not possible for the BCT-5 alone to cause a detonator being tested to function. Always ground yourself and the detonator prior to testing. Use the BCT to test electrically fired initiators; detonators; matches; and pyrotechnic devices that have been manufactured following I.M.E guidelines.
