Barometer logger sensor NUL-221

This logger sensor measures atmospheric barometric pressure and can display data in four common units.

• kPa – kilopascal
• atm – atmospheres
• in Hg – inches of mercury
• mm Hg – millimeters of mercury The sensor also offers an option to display the measured pressure values in terms of altitude (in meters).

Barometric pressure can be measured at sea level (1 atm) and also on mountains (lower than 1 atm).
