GfG Micro 5 G222E — compact two-gas detector (toxic gases, H₂, O₂)
The GfG Micro 5 G222E is a rugged, compact two-gas detector with two electrochemical (EC) sensors, the first in the Micro 5 series. It is designed to detect toxic gases, hydrogen (H₂) and oxygen (O₂), with individual sensor selection (sensors available for over 20 gases). Intelligent, easily replaceable sensors, low weight and an operating time of up to nine months make it an economical tool for long-term use.
