Hobo S-BPA-CM10 – Onset
Barometric pressure sensor compatibel with the H22 data logger
The barometric pressure sensor provides average barometric pressure for each data logging interval over the range of 660 mb to 1070 mb (19,47 to 31,55 inHg). The operating temperature range for this sensor is -40° to 70°C: sensor survival is supported from -20° to +70°C. This specialized smart sensor must be used inside a data logger enclosure to assure protection from direct exposure to the weather.
This is a specialized smart sensor with and is compatible with H22 data loggers. This sensor operates in an outdoor environment and the sensor supports the following measurement: barometric pressure.
