There is a plurality of probes electrically connected to a central controller. Each of the probes is capable of providing a hydrocarbon signal, a water signal and a dry signal upon sensing these respective environments. The controller includes an audible alarm transducer and a switch for activating circuitry providing either a first alarm mode which provides an alarm in response to a hydrocarbon signal or a second alarm mode which provides an alarm in response to a hydrocarbon signal and also a water signal. A continuous alarm tone is provided upon receiving a hydrocarbon signal while an intermittent alarm tone is provided upon receiving a water signal. A yellow label links a 'water' sign and the transducer and a red label links an 'oil' sign and the transducer. The yellow label encircles only a small portion of the transducer and the red label encircles the major portion of the transducer so as to provide a visual indication that the shorter, intermittent tone indicates water while the longer, continuous tone indicates hydrocarbon.
