Pressure Calibration

The Levelogger 5 is calibrated against a range of set reference points to an accuracy of 3 decimal places. During the calibration procedure, the Levelogger is fully submerged in a highly accurate water bath, until conditions are stable. The pressure is then calibrated to six separate pressure points covering the entire range of pressure to check for any non-linearity. The process is repeated again at two different temperatures to check for temperature effects. Once done, the Levelogger is approved after all specifications for accuracy, precision, stability and hysteresis have been met. The Levelogger should be calibrated for the life-time of the instrument as long as it is used within its given technical specifications, in compatible monitoring environments with routine inspections, and is not physically, chemically or thermally damaged.
