Description:
- H₂S & NH₃ adopt high-stability electrochemical sensors to quantify typical malodorous core toxic gases in sewage and breeding industries;
- TVOC uses PID photoionization sensor to capture all volatile organic waste gas;
- O₃ ozone electrochemical sensor monitors disinfection tail gas and photocatalytic oxidation by-products;
- Odor composite odor is jointly characterized by the superposition data of H₂S+NH₃+TVOC to realize overall odor intensity grading evaluation.
Features:
- Real-time synchronous measurement of H2S, NH3, Odor, TVOC and O3; support flexible configuration of 1~5 different gas sensors according to actual demands
- Dual sampling structure available for selection: natural diffusion detection mode and 1L/min constant flow pump suction sampling mode
- Imported dedicated industrial sensors & odor sensing probes, response time controlled within 10 seconds with high measurement stability
- Sound, light and vibration three-dimensional alarm reminder system, ensuring effective early warning in open-air garbage yards and humid sewage workshops
- High-definition LCD screen displays gas concentration value, gas name and current alarm working state synchronously for intuitive viewing
- Built-in data storage chip, capable of saving 9999 groups of alarm records to facilitate on-site operation record filing and later data trace analysis
- Ex ib IIB T3 explosion-proof structure plus IP65 waterproof and dustproof shell, adapting to humid, dusty and corrosive outdoor odor detection environments
- Excellent long-lasting power performance: 100 hours of continuous working time when the built-in air pump is closed
- Freely switchable Chinese and English system interface, compatible with multiple common measurement units: PPM, %VOL, %LEL, mg/m³
- Wide operating temperature range of -40℃ ~70℃, maintaining stable detection effect under high temperature and low temperature field conditions
- Internal stainless steel filter effectively blocks water mist and solid impurities, protects each sensor component and keeps smooth gas intake
