Wireless Pressure Sensor

Product Code: PS-3203


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
