Castle Group, Inc. (The) GA690

The Castle GA690 is a digital barometer designed for measuring atmospheric pressure with a high degree of accuracy and repeatability. It is an instrument of choice for applications that require precision monitoring of the environmental barometric pressure. Results are given in mb (millibars), hPa (hectopascals) and mmHg (millimeters of mercury). The GA690 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 altitude. Simple to operate with clear LCD display. Readings in mb (millibars), hPa (hectopascals) and mmHg (millimeters of mercury). Altitude correction for pressure at sea level. Minimum and maximum readings.
