Gas Pressure Sensor

Use the Gas Pressure Sensor to monitor pressure changes of a gas in chemistry and biology experiments.

SKU: GPS-BTA Categories: ,


The Gas Pressure Sensor can be used to monitor pressure changes in a gas. The range is wide enough to perform Boyle’s law yet it is sensitive enough to conduct vapor-pressure or pressure-temperature experiments. Biology teachers can use the Gas Pressure Sensor to monitor transpiration or respiration in an enclosed environment.

Pressure Range: 0 to 210 kPa (0 to 2.1 atm or 0 to 1600 mm Hg)
Accuracy: ±4 kPa
Maximum pressure that the sensor can tolerate without permanent damage: 405 kPa (4 atm)
