The model A2G-05 Eco differential pressure gauge is used for monitoring the differential pressure in ventilation and air-conditioning applications. The measuring ranges cover from 0 … 50 Pa to 0 … 12,500 Pa. Plus/minus ranges can be fulfilled from -25 … +25 Pa to -1,500 … +1,500 Pa.

The separated construction of the pressure measurement chamber and display area ensures that impurities from the process air do not settle on the back of the window. As a result of the 2-part construction (measuring element and
mounting ring), the A2G-05 can be exceptionally easily and quickly mounted.

The differential pressure gauge is available with ingress protection IP54 and IP65.

In a special version, the A2G-05 is available as a silicone-free product.
