PASPORT Absolute Pressure Sensor

Product Information

Our Absolute Pressure Sensor measures pressure relative to an internal reference vacuum, allowing students to make consistent pressure measurements above and below the ambient conditions.
Typical Applications:
Measure chemical reaction rates
Explore Gas Laws (Ideal, Charles', Boyle's)
Study Vapor Pressure vs. Temperature
Specifications and Special Features:
Range: 0 - 700 kPa
Accuracy: 2 kPa
Resolution: 0.1 kPa
Repeatability: 1 kPa
Displays in N/m2 and PSI
Use the optional Ideal Gas Law Syringe by connecting a Pressure Sensor and a Temperature Sensor to this syringe; students can quantitatively look at the relationships between pressure, temperature and volume.
How It Works: A low thermal mass thermistor is mounted within the syringe for real-time measurement of temperature changes inside the syringe. Tubing and a quick connect port allows a Pressure Sensor to be directly connected to the syringe. As the plunger of the syringe is depressed, the volume decreases while pressure and temperature increase. The data will help students better understand the Ideal Gas Law.
A mechanical stop is included on the syringe plunger to prevent damage of the thermistor within the syringe and to allow quick (adiabatic) volume changes.
Typical Applications:
-Discover or verify the Ideal Gas Law
-Investigate relationships such as pressure vs. temperature (Gay-Lussac's Law), pressure vs. volume (Boyle's Law) and temperature vs. volume (Charles' Law)
-Calculate the number of moles of air in the syringe based on pressure, temperature and volume measurements
Includes:
-Ideal Gas Law Syringe
-Built-in Fast Response Thermistor Probe
-Quick Connect Pressure Port
