Product Overview
The SI-100 is a fixed gas detection system designed for reliable monitoring of combustible gases, toxic gases, and oxygen in industrial environments. It provides accurate, real-time detection with visual, audible, and relay-based alerts, and supports RS-485 digital communication for integration into control systems.
- Multi-Gas Detection: Monitors combustible, toxic, and oxygen levels.
- Reliable Sensors: Long-life catalytic, IR, electrochemical, and galvanic sensors.
- Fast Response: Rapid detection with response times under 30 seconds.
- User-Friendly Operation: Non-intrusive input via magnetic wand and optional RS-485 interface.
- Robust Design: Aluminum transmitter and stainless steel sensor housing with IP-rated protection.
- Flexible Integration: Supports relay, analog, and digital outputs for control systems.
- Certifications: Explosion-proof approvals including KCs, IECEx, and INMETRO.
