The easiest way to trouble-free pressure measurement

PTH is a series of pressure transmitters ideal for monitoring and controlling pressure differentials in ventilation systems. PTH transmitters are particularly suitable when a measurement of the actual air pressure is required for demand control ventilation. They are extremely compact and are designed for direct installation at the measuring point. PTH transmitters are exceptionally compact and easy to install as there is ample room for attaching cables.
