Description

The EGE Elektronik STS 215 KH is the authoritative choice for industrial applications where standard air flow sensors would fail due to thermal stress. The “KH” designation identifies this unit as a high-temperature variant, capable of continuous operation in media temperatures ranging from -20°C to +120°C. The STS 215 KH is built with an extended probe length, specifically engineered to reach deeper into large-diameter hot air ducts or insulated pipes. This ensures the calorimetric sensing tip is positioned accurately within the core of the airflow, away from the boundary layers of the pipe wall, providing more reliable and repeatable data.
