Extractable flue gas humidity analyzer for CEMS and high-temperature, high-dust industrial exhaust environments.
The DABECO DB460 humidity analyzer is widely used in continuous emission monitoring systems (CEMS) for flue gas humidity measurement. It is also suited to humidity measurement and control in wood, building materials, paper, chemical, pharmaceutical, fiber, textile, tobacco, vegetable, and food processing applications. For low-temperature, high-humidity, and high-dust environments, the extraction sampling design with optional electric heat tracing provides a reliable flue gas humidity solution.
The DB460 uses a capacitance-method sensing element housed in a wall-mounted cabinet, drawing sample gas via an extraction (split/pumped) sampling method rather than in-situ insertion. Optional electric heat tracing (50-150°C) keeps the sample line above dew point to prevent condensation before it reaches the sensor, which displays either volume ratio or relative humidity (one mode at a time, specified at order) on a four-digit tube display, with 4-20mA analog and RS485 digital outputs.
