A high output smoke generator suitable for use as a portable apparatus employs a thin-walled metal conduit as a resistance heater coil which also doubles as a thermal sensor. A balance bridge controller using the coil as one leg in the bridge network, is electrically coupled to provide current to the resistance heater coil for maintaining the coil at a predetermined temperature. A thermocouple used for calibration is electrically isolated from the coil by a beryllium oxide disk. Also, disclosed are a fluid reservoir and pump to provide smoke generating fluid reservoir and pump to provide smoke generating fluid to the coil after an adjustable time delay from startup, and a timer to shutdown operation after a preselected period.
