PASPORT Absolute Pressure Sensor - PS-2107


The Absolute Pressure Sensor and included components.


Make accurate and consistent measurements of gas pressure, regardless of ambient conditions and explore how chemical reactions affect gas pressure.  

Our Absolute Pressure Sensor measures pressure relative to an internal reference vacuum, allowing students to make consistent pressure measurements above and below the ambient conditions.

Together with a temperature sensor a wide variety of concepts can be explored.

    Go Wireless!

    Recommended Alternative — The Wireless Pressure Sensor can perform most of the functions of the Absolute Pressure Sensor (Range is lower 0-400 Pa vs 0-700 Pa) at a lower price. Best of all, it connects directly* to your computers, tablets, smartphones and Chromebooks without the need for an interface and with no cables to get in the way.

    *Devices without native Bluetooth® Smart connectivity will require a low cost USB adapter - see the product page for details.
