sgd Fixed gas detector | Highseek

sgd Fixed gas detector

The SGD Series is a next-generation gas detection solution engineered by HighSeek to meet the rigorous safety demands of modern industrial environments. Leveraging years of field expertise and cutting-edge sensor technology, the HighSeek SGD gas detector provides continuous, real-time monitoring of gases with temperature and humidity together for the best accuracy based on the real ambient environment compensation.
Designed for seamless integration, whether deployed in Petrochemicals, Mining, Aerospace, or Municipal Engineering, the HighSeek SGD stands as a reliable guardian of personnel safety and asset integrity.

Unrivaled Reliability & Compliance

Built upon a foundation of global industrial standards: ATEX, IECEX, SIL, CE, FCC, and ROSH. Unique explosion-proof design guarantees both of the safety and high sensitivity

Advanced Connectivity

Engineered for the era of Industrial IoT (IIoT), the SGD supports the traditional wired connections (4-20mA, RS485, CAN bus, Hart) to cutting-edge wireless modules (NB-IoT, 4G, Lora, WiFi, Bluetooth).

Intelligent Remote Protection

Through the HighSeek cloud server, users can perform remote parameter configuration, alarm threshold settings, and remote calibration.

Extreme ANTI-CORROSIon

Specifically engineered for high-humidity and corrosive settings, SGD has passed the 720H salt spray test (SST). This exceptional durability makes it the ideal choice for offshore, marine, and chemical plants.
