Overview
This serves as a lightweight, hand-held tool combining gas detection, multimeter functions, and environmental sensing. It covers a wide range of combustible gases (e.g., hydrogen, methane, CO, phosphine) with excellent responsiveness and built-in auto-ranging. Users benefit from real-time LCD readouts alongside intuitive analog bar, LED, and audible alarms. The device also measures temperature and humidity—making it highly versatile for safety inspections in industrial, environmental, or maintenance applications.
Features
