The new gas detector H2S from Automatikprodukter, Sweden is designed to protect people, equipment, and plants from risks associated with hydrogen sulphide (H2S). The unit features Modbus communications protocol to facilitate fieldbus communication.
Hydrogen sulphide is a toxic gas whose odour is usually described as similar to the odor from rotten eggs. At high concentrations, there occurs a paralysis of the sense of smell. It is therefore not possible to use smell to determine if an area is dangerous due to the presence of hydrogen sulphide.
