Hydrogen sulfide is a colorless, odorous, flammable gas, which is irritating and suffocating, it is harmful to the human body. Renke hydrogen sulfide sensor adopts electrochemical principle, which is sensitive in response and strong in anti-interference ability. In order to meet the requirements of different places, we provide four types: wall-mounted H2S sensors, duct type H2S sensors, portable H2S detectors and fixed H2S detectors. Our wall-mounted H2S sensor has RS485 hydrogen sulfide sensor and analog hydrogen sulfide sensor (4-20mA/0-5V/0-10V) optional.

The H2S sensor designed by our company adopts the imported first-line brand electrochemical hydrogen sulfide sensor, which has the characteristics of rapid response and strong anti-interference ability.

Features of H2S sensor

1. Imported first-line brand electrochemical sensors are used, which are stable and durable. 2. Range 0-100ppm, other ranges can also be customized. 3. The measurement accuracy is high, within ±3% FS, and the repeatability can reach within 2%. 4. A variety of analog signal output options: 4~20mA/0~5V/0~10V/RS485 5. Optional high-quality OLED display, the value can be viewed directly on site, and can be displayed clearly at night. 6. On-site power supply adopts 10~30V DC wide-voltage power supply, which can adapt to a variety of on-site DC power supplies. 7. The H2S sensor adopts a wall-mounted waterproof shell, which is easy to install and has a high degree of protection, which can be used in harsh on-site environments.
