Description
Overview
GAOTek Hydrogen Cyanide gas detector is used for the occasions where rapid detection of hydrogen cyanide gas concentrations, temperature and humidity measurements, and over-standard alarm. It adopts a 2.31 in high-definition color screen for real-time display and uses imported gas sensors from well-known brands.
Features
- Human-machine interface
- Built-in pump suction
- Fast response
- High temperature gas detection
- USB charging interface
