DIGITAL BAROMETER / BAROGRAPH Brown

The Steamrock NB-42 digital barometer detects and records changes in atmospheric pressure. It displays current atmospheric pressure, a graph showing changes in that pressure over 84 hours, and a World Meteorological Organization (WMO) symbol depicting changes over three hours. Atmospheric pressure is measured every 15 minutes and is stored in a built-in memory. This model requires the use of a dedicated smartphone app for setting up and controlling it utilizing NFC technology. However, after setup, it acts as a standalone device that does not require software updates, an internet connection, or an external power supply. It operates on three AAA batteries up to one year, with remaining charge displayed using a battery icon and percent remaining number. Thus, it can be used as an aid to navigation and an instrument for weather observation. Two Pressure alarms (Upper and Lower), and two 3-hour trend alarms (Rising and Falling). Configure settings easily with the dedicated app via your smartphone’s NFC. Absolute or Sea Level Pressure (hPa, inHg). 84-hour atmospheric pressure graph. 3-hour pressure tendency symbol and value.Tested at sea.
