Testifire从特殊配方的、在可更换的非加压胶囊中提供的流体中产生无毒的烟雾刺激。胶囊的试验次数由被测试探测器的响应时间决定，范围在500至1000个试验之间。虽然比较起来比材料成本要多得多，但通常这相当于气溶胶产生的2至5倍。
Testifire generates its nontoxic smoke stimulus from a specially formulated , fluid supplied in a replaceable non-pressurized capsule. The number of tests from a capsule is dictated by the response time of the detectors under test and can range between 500 and 1000 tests .Although there is much more to the comparison than material cost , typically this equates to between two and five times that produced by an aerosol.
