The Marine Moisture Control Company has recently issued a data sheet on its tank temperature indicator. The indicator fills the need for a highly accurate unit which shows easily visible tank temperature readings. Available in four stations to 20 station units, the tank temperature indicator is rated intrinsically safe by the U.S. Coast Guard. The data sheet includes a schematic diagram.
