SKU: ERANNTEX Online Odor Detector
Eranntex GTYQ-MIC-600 Online Odor Detector is the preferred choice for multi-scenario gas monitoring procurement. It continuously monitors odorous gases including OU, ethanol (C₂H₆O), methanol (CH₄O), methylamine (CH₅N), methyl mercaptan (CH₃SH), and more, while simultaneously measuring temperature and humidity. Data is clearly displayed on a 2.5-inch high-definition color screen. Triggers audible and visual alarms upon gas concentration exceedances. Supports remote data transmission, enabling real-time monitoring from remote locations. Incorporates premium electrochemical and infrared sensors paired with advanced circuitry and proven algorithms for precise, stable detection. Holds software copyright and design patents. Explosion-proof housing with fluorocarbon coating ensures corrosion and wear resistance, suitable for factory pipelines, confined spaces, and similar environments.
Online Odor Detector Description: Industrial gas detection equipment faces heightened demands in complex environments like tunnel construction, coal mining, and chemical production facilities, where gas compositions are diverse and challenging. Multi-gas detectors, with their robust capabilities, emerge as the ideal solution for such demanding conditions.

Take coal mining as an example: underground environments contain methane, carbon monoxide, hydrogen sulfide, nitrogen (N₂), vinyl chloride (C₂H₃Cl), trichloroethylene (C₂HCl₃), tetrachloroethylene (C₂Cl₄), chloroform (infrared) (CH₃Cl), dichloroethane (infrared) (C₂H₄Cl₂), dichloromethane (infrared) (CH₂Cl₂), trichloromethane (infrared) (CHCl₃), Nitrous Oxide (Infrared) N₂O, Nitrogen Trifluoride NF₃, Hydrogen Peroxide H₂O₂, Styrene (PID) C₈H₈, Tetrahydrofuran (PID) THF, TVOC (PID), and other gases. Methane is the primary factor causing gas explosions, carbon monoxide can lead to personnel poisoning, hydrogen sulfide possesses strong corrosivity and toxicity, while abnormal nitrogen levels may also impact personnel respiratory safety. The composite gas detector is equipped with multiple sensor types, enabling comprehensive detection of these gases.
The GTYQ-MIC-600-OU online odor detector employs advanced circuit design and mature core algorithm processing technology, ensuring not only high detection accuracy but also exceptional reliability. For instance, it detects carbon monoxide at the ppm level, promptly identifying even minute leaks. Additionally, this detector offers multiple display modes: its 2.5-inch high-definition color screen simultaneously shows multiple gas concentrations, cycles through single-channel readings in large font, and displays real-time curves, enabling operators to intuitively monitor gas fluctuations.
Therefore, when procuring gas detection equipment, factors like explosion-proof performance and protection ratings must be considered. These complex environments often involve harsh conditions such as high temperatures, humidity, and dust, and may contain flammable or explosive gases. Only a multi-gas detector with robust explosion-proof certification and high protection ratings can operate reliably in such settings. Simultaneously, its data storage and transmission capabilities are crucial for convenient recording and analysis of detection data. If your workplace faces complex gas detection challenges, consider investing in a high-quality multi-gas detector. It will eliminate your concerns, ensuring smooth operations and personnel safety.
