Frequently Asked Questions FAQ for Sulfur Dioxide Detectors
Q1: How should the split sulfur dioxide detector be installed for flue gas and atmospheric monitoring?
A: The probe should be installed within one meter of the possible gas leakage or emission point, considering the vapor density of sulfur dioxide (which is heavier than air) and local wind direction. Ensure the sensor surface faces downwards, and install a rain shield if used outdoors. The open-area detection radius covers up to 60 square meters.
Q2: Can the alarm settings and monitoring ranges be customized for low-concentration atmospheric testing?
A: Yes! The HNAG1000 supports ultra-low ranges like 0-1ppm dedicated for atmospheric monitoring, as well as multi-level ranges up to 40000ppm. It features standard two-level alarms (with optional three-level settings) to perfectly match your specific project requirements.
