The 3001 Barologger Edge is designed for use in air only. It has a specific range and firmware algorithms based on air pressure rather than water pressure. This makes the Barologger less accurate if used in water, but more accurate if used as intended, in air. Using a Barologger is the most accurate and convenient method of obtaining atmospheric pressure and air temperature. When programmed with the same sampling parameters as the Leveloggers on site, a Barologger can avoid barometric data time lags and any errors introduced due to moisture buildup, kinking or damage to vented cable. The Barometric Compensation Wizard in the Levelogger software simplifies the adjustment of the level measurements for barometric pressure changes, by using the synchronized data from all Leveloggers on site and the site Barologger.
