摘要: Tracer gas leak detection is provided by a calibration system with detector having test port for receiving sample containing tracer and coupled to vacuum pump; calibrated the gas; mass filter in an operating mode, through valve controllable transmission of providing filtered sample; detecting programmable gain element measured value rate response signal; controller configured, mode control signal, operate over two or more working ranges using leak.
