Gas Pressure Sensor
Recommended for College, High School, and K-8. Interface and software sold separately.
Use the versatile Gas Pressure Sensor to monitor pressure changes of a gas in chemistry and biology experiments.
Description
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.
Specifications
- Pressure Range: 0 to 210 kPa (0 to 2.1 atm or 0 to 1600 mm Hg)
- Maximum pressure that the sensor can tolerate without permanent damage: 4 atm
- Resolution: 0.05 kPa (0.0005 atm or 0.40 mm Hg)
(LabQuest 2, LabQuest, LabQuest Mini, Go!Link, LabPro)
- Sensing Element: SenSym SDX30A4
- Combined Linearity and Hysteresis: typical ±0.2% full scale
- Response Time: 100 microseconds
