Using 3rd-party barometric pressure data for compensation

HOBOware Pro's Barometric Compensation Assistant now includes the ability to import barometric pressure data from 3rd-party sources such as nearby weather stations. The data needs to be provided in a text data file, and can be in kPa, Pa, mbar, mm HG, psi, or inches Hg. For more information, see the User's Guides for the Barometric Compensation Assistant and the HOBOware Pro software (Importing Data section) or in HOBOware under Help, HOBOware Help.

Altitude effects on water level data logger range

Onset's HOBO® U20-001-01 Water Level Data Logger is calibrated from 10 to 30 psia. The 10 psia lower limit creates an effective altitude restriction of about 10,000 feet when the data logger is used. The unit can be used above 10,000 feet, but it is outside of the calibrated range, and the accuracy specification does not apply. The data logger will function, but the accuracy will get worse the further below 10 psia the pressure drops.
