Product Overview
Senko SI-H100
The SI-H100 is a compact, highly reliable sampling gas detector developed by SENKO. Designed for industrial environments, it draws in gas samples through an internal pump and measures them with precision sensors. With an intuitive LCD display, powerful alarms, and versatile connectivity options, the SI-H100 ensures safety monitoring across a variety of applications.
Its design allows easy maintenance, efficient sampling up to 30 meters, and stable operation with low power consumption. The SI-H100 supports multiple output methods, including analog, relay, and digital communication (RS-485, Ethernet), making it suitable for integration into different safety management systems.
