AIKE EM-20I Portable Multi-Gas Detector

Product Description

The AIKE EM‑20I is a portable multi-gas detector engineered for industrial safety applications. It provides reliable, real-time detection of toxic, combustible, and oxygen gases. Moreover, its rugged explosion-proof housing ensures safe operation in hazardous environments, including coal mines, petrochemical plants, metallurgy, municipal gas systems, tunnels, and confined spaces. The device delivers precise measurements, allowing operators to monitor gas concentrations efficiently and prevent accidents.

Equipped with a large LCD screen, the EM‑20I shows instantaneous, peak, and minimum values, along with battery status. Furthermore, it offers multi-mode alarms—audible, visual, and vibration—to guarantee worker safety in critical situations. Designed for portability, the detector combines high accuracy, long sensor life, and user-friendly operation for industrial professionals.

Key Features
