KFBH - 60 Refinery Gas Guardian
Introduction
Refinery Gas Guardian: KFBH - 60 is specifically designed for refineries. Using a wall, pipeline, or flow - through sampling method, it quickly and accurately detects gas leaks. With a response time of ≤30S and recovery time of ≤10S, it ensures timely alerts. Its high - brightness LED display shows real - time gas concentration. The device has a compact design with dimensions of 190×150×95mm and is suitable for long - term installation in refineries to prevent gas - related accidents.
Product Features
1. Multiple sampling methods for refinery - specific needs.
2. Fast response and recovery times.
3. High - brightness LED display for easy monitoring.
4. Compact design for easy installation.
