Description

Honeywell Midas-M Oxygen (O2) Sensor, 0-25% v/v, 3 years

The Midas-M Sensor Cartridge enables the detection of a wide range of asphyxiant, toxic, flammable, pyrophoric, corrosive, and oxidizer gases. The plug & play Sensor Cartridge is located inside the detector’s chassis.

Cross Sensitivities

Each Midas-M sensor is potentially cross sensitive to other gases and this may cause a gas reading when exposed to other gases than those originally designated. The table below presents typical readings that will be observed when a new sensor cartridge is exposed to the cross sensitive gas (or a mixture of gases containing the cross sensitive species).

HydrogenH2100% v/v-9
MethaneCH4100% v/vNo response
Nitrogen DioxideNO225 ppm in airNo response
