The Solo 365 uses non-hazardous, non-pressurized cartridges to generate smoke safely and efficiently. Its built-in proximity sensor automatically triggers smoke release when the detector enters the test cup, while the clearing mode disperses lingering smoke to prevent false or repeat alarms. The lightweight, slim design allows easy access to tight spaces and works seamlessly with Solo access poles for extended reach. With a built-in LED light, it simplifies testing in dim or hard-to-reach areas.
