Lots of information such as vapor pressure, gas pressure sensor, and pressure transducer are described inside this datasheet. The datasheet presents information related to sensor, and pressure.
In this datasheet we can find info about instruments, pressure sensor, and calibration point. These are chosen from the datasheet:
The Vernier Gas Pressure Sensor is used to monitor pressure changes in gas-law experiments in chemistry and physics, such as Boyle’s law (pressure vs. volume) and Gay-Lussac’s law (pressure vs. absolute temperature). Vapor pressure of various liquids and solutions can be monitored using this sensor. Biology teachers can use the Gas Pressure Sensor to monitor the production or consumption of oxygen or carbon dioxide gases in an enclosed atmosphere.
Also, this datasheet explains discussion regarding the gas pressure, and calibration.
