The TruBlue 575 BARO Data Logger is an absolute non–submersible pressure transducer. This unit provides local atmospheric pressure data that can be used to compensate one or more submerged, non–vented water level transducers. An absolute format measures all pressure applied to it including atmospheric. If submerged, it measures the atmospheric pressure plus pressure exerted by the column of water above the sensor. A level value can be arrived at using two absolute transducers–one submerged and one at ground level–subtracting atmospheric pressure from the submerged transducer measuring water pressure. The TruBlue 575 BARO is the perfect choice to measure barometric pressure when reliability, accuracy and precision matter.
