The Natural Gas Services 'Proving & Environmental Control System' is in use in numerous school laboratories where it monitors the condition of gas taps. Any open or partially open tap is detected and the main gas to the classroom is prevented from opening.
The units can be used to protect one classroom or several classrooms dependant upon pipework configurations.
