Vernier Sensor - Gas Pressure Sensor

The Vernier Gas Pressure Sensor is an easy-to-use tool for monitoring pressure changes in gaseous samples. With a range of 0 to 210 kPa (0 to 2.1 atm) and a maximum pressure rating of 4 atm, it's versatile enough for Boyle's law (pressure vs. volume) experiments and sensitive enough for vapour-pressure and pressure-temperature studies.

Driven by the Honeywell SSCMRNN030PAAA5 piezoresistive silicon pressure transducer, the sensor delivers high resolution and a fast 100 µs response time. It connects to Vernier interfaces and can also be used with Arduino via the Vernier Arduino library.

Key Features
