## Description

This is the Vernier Gas Pressure Sensor, an easy to operate tool that can be used to monitor pressure changes of a gaseous element. The range on this Vernier sensor is wide enough to perform pressure vs. volume (Boyle’s law) experiments yet it is sensitive enough to conduct vapor-pressure or pressure-temperature experiments.

These Gas Pressure Sensors offer the user to test in a pressure range of 0 to 2.1 atm (0 to 210 kPa) to a max of 4 atm. Driving this sensor is the Honeywell SSCMRNN030PAAA5 pressure transducer, a fully capable piezoresistive silicon pressure chip that more than meets the requirements for any teacher, student, or enthusiast who uses this Vernier add-on.

Vernier Software and Technology has been a leader in data collection and analysis for educators world-wide. They were amongst the first companies to design and promote the use of computers, sensors, and data collection in K-12 classroom laboratory experiments.

**Note:** Due to manufacturer’s restrictions, we can only ship these to the USA. Sorry world!
