Description
The MMC Flexi-Dip Oxygen Sensor Gauging Tape is a battery-operated electronic system featuring the latest in solid-state circuitry and an easy-to-view LCD readout panel. A built-in auto-calibration feature allows the unit to automatically calibrate to 20.9%. It offers a fast, safe and convenient method for measuring oxygen content within the ullage space of a closed tank–the space between the top of the tank and the liquid cargo below. The precise measurement of void space oxygen levels is a crucial consideration for petroleum-carrying vessels which blanket their liquid cargos with inert gas to prevent combustion and explosion. In order to maintain the proper inert gas conditions aboard tanker ships, oxygen levels must be minimized and, according to U.S. Coast Guard regulations in the United States, monitored and documented.
