High Precision HF Gas Detector with Hot Swap Sensor for Continuous Monitoring Hydrogen Fluoride Detector

The SG100 series is a cost-effective fixed gas detector engineered for continuous monitoring of toxic gases, oxygen, flammable gases, and VOCs. It is IECEx and ATEX certified with an intrinsically safe explosion-proof grade. Featuring 2-wire or 3-wire 4–20 mA analog output, RS485 Modbus output, and optional HART output, it is compatible with most control systems. Optional wireless data transmission allows customers to review and download data remotely. The detector supports both magnetic and remote control for flexible configuration.

• Confined Space Entry: Gas monitoring for tanks, tunnels, vessels, and enclosed working areas.
• Oil & Gas: Explosion-proof detection for refineries, fuel stations, and offshore platforms.
• Environmental: Emission testing for landfills, wastewater plants, and ecological monitoring.
• Fire & Hazmat: Emergency gas detection for fire rescue and chemical spill response.
• Industrial Hygiene: Workplace toxic gas inspection for factory occupational safety.

• IP66/IP68 water and dust resistant housing for demanding environments.
• Intelligent plug-and-play sensor module supporting calibration via Safegas PC software for easier replacement and maintenance.
• Standard splash guard for outdoor installation or environments with water splash.
• Compact and lightweight design weighing only 1 kg, with standard mounting bracket for easy installation.
• Standard 4–20 mA analog signal output and RS485 Modbus signal output, with optional HART output and 2-wire output, compatible with most control systems.
• Includes 3 relays for low/high/fault alarm (optional).
• Supports both magnetic and remote control for flexible configuration.

As a professional gas detector manufacturer, we control the entire process from design and R&D through production and sales to ensure consistent product quality. We hold more than 100 independent intellectual property patents in design and development. In production, we employ skilled technical workers and maintain a complete industrial line to manage production and quality throughout the process. Our company has rich overseas sales experience and a professional sales team that provides customers with considerate 7×24 hour service.

We have a professional R&D department with approximately 25 years of experience in the gas detection industry. Their professional knowledge and rich experience enable us to provide customers with expert technical after-sales service.

We implement a strict quality management system with the principle of quality first as the core to produce gas detectors. As a result, we have been recognized by authoritative organizations and obtained ISO9001 and ISO14001 certifications, providing customers with safe and environmentally friendly products.

Our products have obtained IECEx and ATEX explosion-proof certification, enabling our detectors to be used in hazardous areas such as mines, underground locations, and oil plants. We are the first and currently the only manufacturer in China to obtain this certification. Products without explosion-proof certification are prohibited from use in dangerous areas.

Our core components, such as ICs and sensors, use imported brands, improving product accuracy, stabilizing service life, ensuring detection accuracy, and protecting customer safety.

Our complete product line and stable inventory provide customers with fast delivery. For orders of fewer than 10 pieces, we typically deliver within 3 days. For quantities exceeding 100 pieces, we can deliver within half a month under normal circumstances.
