Product Features
This online hydrogen sulfide gas analyzer adopts original imported infrared, catalytic combustion and electrochemical gas sensors, featuring sensitive response, excellent stability and a service life of more than 3 years. Designed with a flameproof structure, the device supports on-site LCD data display and local audible and visual alarm prompts.
It features a wide working voltage range. With a standard DC 24V power supply, the analyzer works stably under voltage fluctuations from 18V to 30V DC. Strong electromagnetic interference resistance guarantees accurate and reliable signal transmission in complex industrial environments.
Equipped with reverse wiring protection, the instrument will not be damaged by incorrect on-site wiring. Professional circuit design provides output signal protection, ensuring the signal current does not exceed 21mA in any fault state.
Adopting advanced SMT surface mount technology, the equipment achieves higher integration and operational stability. The whole shell is made of 304 stainless steel, which is corrosion-resistant and long-lasting.
Internal constant temperature treatment ensures stable operation in low-temperature winter environments. The built-in intelligent sample gas pretreatment system realizes three-stage gas purification. Filtered impurities and wastewater are discharged automatically without manual operation, effectively extending the service life of the sensor.
