Frequently Asked Questions
What detection principles are used in this odor monitor?
The monitor uses three distinct sensor principles—Electrochemistry, Photoionization (PID), and Semiconductors—configured in an array sensor group to ensure rapid response times and robust anti-interference capability.
What target gases and ranges can the device measure?
It measures Odor level (0~70), Ammonia (0~100 ppm), Hydrogen sulfide (0~100 ppm), Methyl mercaptan (0~20 ppm), and Volatile organic compounds (VOCs) with optional ranges of 0~50 ppm or 0~6000 ppm.
Is this device suitable for harsh outdoor environments?
Yes, it features a rugged PELICAN protective box design with an IP65 protection rating, making it rainproof, dustproof, and resistant to salt spray.
How long does the battery last on a single charge?
The built-in lithium battery supports up to 8 hours of continuous operation under normal working conditions, and the battery capacity can be expanded if required.
What are the primary applications for this Odor Detector?
It is widely applied in sewage treatment plant inspections, landfill monitoring, chemical plant emission testing, river odor gas detection, industrial park environmental testing, and food processing facility monitoring.
