Low Gas Alarm System Using Contact Gauge

Reliable Gas Level Monitoring with Visual and Audible Alerts

Product Overview

Our Low Gas Alarm System is designed for accurate and dependable monitoring of gas levels in cylinders, tanks, and vessels. Featuring dual-color LED indicators alongside an audible buzzer and external relay activation, it provides clear alerts when gas levels fall below preset thresholds. The system supports both Normally Closed (NC) and Normally Open (NO) contact gauges, configurable on-site via the control panel for maximum flexibility.
