Oxygen Meter
KM 5491
The KM 5491 Portable Oxygen detector is a kind of essential safety
instrument which can continuously detect the Oxygen concentration
in the working environment. It is suitable for explosion-proof, toxic
gas leakage, undergound pipelines or underground mines & other
places.
The instrument is a natural diffusion method for detecting gas
concentration, using high performance electrochemical sensor,
with excellent sensitivity & excellent repeatability. The instrument
adopts embedded micro control technology, simple operation,
complete functions, high reliability.
