It is suitable for use in blasting operations of under-ground mining and open mining where no explosion hazard of marsh-gas and mine dust exists and can be used for fulfilling once-ignition to achieve the effect of large-area millisecond blasting. It is accurate for delaying action, safe in operation, reliable for function and convenient for easy connection in network.
