What SAM does SAM is a Safe Air Monitor developed for indoor running engines & equipment such as forklifts, floor polishers, and cleaning equipment. SAM measures the quality of the air and notifies the equipment operator if unsafe air quality conditions exist. If the air quality remains poor, SAM automatically shuts down the equipment to prevent operator illness. How SAM works SAM utilizes a factory calibrated internally mounted carbon monoxide sensor to read and monitor ambient air quality. Additionally, SAM uses an oxygen sensor in the exhaust stream to measures the air to fuel ratio of your engine to determine if the engine is running properly or needs service. If poor air quality or high emissions exist, SAM notifies the operator through a series of alarms and shuts the equipment down if no action is taken. SAM also logs the following Engine data: Hours RPMs Temperature Time till next service interval Fuel Level (Propane Option Only) Get Safer with SAM SAM is available online as well as through select distributors. SAM is easily installed on applications and comes with a mounting bracket and universal wiring harness.
