DB481 Datasheet： Humidity Module V251023 Page 1 of 2 DB481/DB481-D High-Temperature Humidity Analyzer Product introduction This high-temperature humidity analyzer adopts internationally advanced dry-wet oxygen measurement technology based on solid-state electrolytic ceramic sensing. Its core sensor features a high-temperature-resistant structural design, with a maximum temperature resistance of up to 400℃, enabling stable long-term operation in high-temperature environments. The product is characterized by high temperature resistance, high measurement accuracy, strong corrosion resistance, fast response speed, and stable and reliable performance. It delivers even more excellent performance in the continuous online measurement of humidity & oxygen under harsh working conditions—such as those involving heavy metals, high corrosion, high humidity, and organic matter interference—in volatile organic compounds (VOCs). Drying rooms, setting machines, and steaming machines, and can also be applied to humidity measurement and control in wood, new energy, papermaking, chemical industry, rubber, fiber, tobacco, and ceramic processing. 250℃/400℃ Dual dust filtration design, effectively filters dust and acidic liquids Equipped with a purge hole for easy user cleaning and maintenance Supports remote calibration and verification Unique heat tracing design, effectively prevents sulfide solidification Probe rod made of 316L material, highly corrosion-resistant Instrument housing with IP65 protection rating Compatible with Dabeco DB43 c
