Students will know about weather changes long before they happen using our Barometer/Low Pressure Sensor. Our Barometer measures extremely small changes in barometric pressure (0.001 in Hg). Even capture the change in barometric pressure from the floor to the ceiling, or the change when a door is closed. The use of digital signal processing gives our Barometer higher resolution.

Now includes quick connect fittings and tube kit for transpiration and other low pressure studies.
