SKU: SB42BK Category:

The Steamrock SB-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. Beneath that symbol is a numeric value representing net value changes over the three hours.

Atmospheric pressure is measured every 15 minutes and is stored in a built-in memory. Results are shown on a high contrast sun readable e-paper display. Steamrock SB-42 is a standalone device that does not require software updates, 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.

Although this barograph is not a tool for extremely precise lab measurement, it is perfectly suitable for keeping track of atmospheric pressure tendencies. Thus, it can be used as an aid to navigation and an instrument for weather observation.
