Pressure Calibration

The Levelogger Edge 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. The bath is allowed to stabilize. 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 water level datalogger should be calibrated for the lifetime of the instrument, as long as it is used within its specified range.
