Measuring dew point in furnace gas
Water vapor is a key component in furnace atmospheres and feed gas, affecting the chemistry between the gas and the metal parts in the process.
Because of the wide variety of thermal heat treatment processes, target dew point temperatures can range from –60°C to elevated levels of +35°C and even higher. Due to the extremely high oven process temperatures typically involved in heat treating, a sampling system/line from the furnace to the dew point probe is normally required in order to cool the process gas before reaching the sensor.
Handheld Dewpoint Meter DM70 for spot-checking applications and field calibration offers accurate and fast measurement for industrial dew point applications, such as compressed air, metal treatment, additive manufacturing as well as food and plastics drying.
Vaisala DRYCAP® Dew Point and Temperature Probe DMP7 is made for tight spaces and low-humidity applications.
