Make accurate and consistent measurements of gas pressure, regardless of ambient conditions, and explore how chemical reactions affect gas pressure. In combination with a temperature probe, study the Empirical Gas Laws. It can also be used in applications that previously required our Low Pressure/Barometer sensor.
The Teaching Advantage
Measures pressure relative to an internal sealed reference vacuum, which allows the collection of reliable data even when the pressure within a system drops below ambient pressure.
Supports common units (kPa, atm, psi, mmHg, or N/m2) for many applications

1 Minimum # of data points with all measurements enabled, actual results depend on enabled measurements.
2 Continuous use in a connected state until battery failure, actual results will depend on sample rate, active measurements, and battery condition.
3 Logging until battery failure, actual results will depend on sample rate, active measurements, and battery condition.
* Normal classroom use is the sensor in active use for 20min/lab for 120 lab periods/yr.
