Air Monitor VOLU-probe instruments measure airflow in primary and secondary air ducts, recirculation lines and other industrial ducts with low pressure loss. A purge system can support use in dusty flue-gas applications.

Body: aluminium or stainless steel. Maximum listed temperature: 80 °C for aluminium or 480 °C for stainless steel. Accuracy: 2–3%. Applications include fan-flow measurement, boilers, industrial dryers, air heaters and HVAC. For a quotation, provide the medium, duct dimensions, flow rate, pressure, temperature, altitude and whether purging is required.
