SG100 Fixed Gas Detector
Product Overview
The SG100 series is a cost-effective gas detector for continuous monitoring of toxic gases, oxygen, flammable, and VOC gases. It features IECEx and ATEX certification with intrinsically safe explosion grade. With 2-wire or 3-wire 4-20mA analog output, RS485 Modbus output, and optional HART output, it is compatible with most control systems. Optional wireless data transmission enables remote data review and download. Supports both magnetic and remote control for flexible configuration.
