Differential Pressure Sensor – Wireless


Wireless differential pressure gauge monitors at low pressure levels. This powerful sensor can be used alongside or as a replacement for Magnehelic gauges when continuous wireless monitoring and alerts are needed.

Ideal for monitoring HVAC filters, exhaust blowers, and differential pressure across clean rooms.

Standard pressure ranges are 0 – 4 in of H20 and 0 – 27.7 in H2O.
