Castle Barometer

The Castle digital barometer is designed to measure atmospheric pressure with a high degree of accuracy and repeatability. It is an instrument of choice for applications that require precise monitoring of environmental barometric pressure. The results are delivered in mb (millibars), hPa (hectopascals) and mmHg (millimetres of mercury). The GPB 3300 gives maximum and minimum results until reset or power OFF and there is an option for sea level correction if users are operating the device at an altitude. This barometer is 106mm x 67mm x 30mm in size.
