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

H2S Sensor

The H2S sensor is duct, the housing is dust-proof and waterproof, with a long using life. IP65 protection grade, can work normally in harsh environments. There is a temperature and humidity probe at the bottom to support measuring temperature, humidity and hydrogen sulfide at the same time. It is suitable for parking lots, garages, workshops, chemical plants, greenhouses, closed living places and other occasions.

Features

• Adopt imported first-line big brand electrochemical sensor, stable and durable.
  Range 0-100ppm, other ranges can also be customized.
• High accuracy, and repeatability within 2%.
• Can add OLED display, the value can be viewed directly on-site, and can be clearly displayed at night.
• It adopts a 10~30V DC wide voltage power supply, which can adapt to various DC power sources on site.
• Optional temperature and humidity hydrogen sulfide 3 in 1 sensor, with high protection level, can be used in harsh field environments.
