SG100-D Series Fixed Multi-Gas Detector
IECEx and ATEX certified fixed diffusion sampling detector with IP66/68 protection, monitoring LEL, CO, H₂S, and O₂ with RS485 alarm functionality.
Product Overview
The SG100-D series represents an innovative intelligent fixed multi-gas detector featuring hot-swappable functionality. Once installed, its hot-swappable design significantly simplifies maintenance procedures. Technicians can replace components such as sensors without shutting down the entire system, ensuring continuous operation in critical gas monitoring scenarios.
This detector delivers high-efficiency gas detection, capable of continuously monitoring up to four different gases within a single unit. Whether detecting common hazardous gases like carbon monoxide, hydrogen sulfide, methane, or oxygen, it provides comprehensive coverage for various industrial and environmental applications.
Safety remains a top priority for the SG100-D series, as demonstrated by its IECEx and ATEX certifications. With an explosion level reaching Ex db IIC T6 intrinsically safe grade, it can be securely deployed in explosive environments such as oil refineries and chemical plants, minimizing ignition risks.
The magnetic wand design enhances both user-friendliness and safety. In explosion-prone areas, operators can use the magnetic wand to navigate menus easily, eliminating the need for direct physical contact while reducing potential spark-induced accidents.

Frequently Asked Questions
Q1: What is a gas detector?
A1: A gas detector is an instrument for gas leakage concentration detection, including portable gas detectors and fixed gas detectors.
Q2: What does a gas detector detect?
A2: Combustible gases: Natural gas (methane), liquefied gas, coal gas, acetylene, pentane, alkynes, toluene, etc. Toxic gases: Carbon monoxide, hydrogen sulfide, ammonia, chlorine, phosphine, sulfur dioxide, hydrogen chloride, chlorine dioxide and other toxic and harmful gases.
Q3: What is the ppm unit of the gas detector?
A3: ppm represents the volume concentration of the gas, meaning the volume of pollutants contained in one million volumes of air. For example, if the concentration of ammonia is 30ppm, it means that the volume of ammonia in one million volumes of air is 30.
