Description

Honeywell Midas-M Sulfur Dioxide (SO2) Sensor, 0-8 ppm, 2 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. Note: The SO2 sensor CANNOT be combined with an O3 sensor in a complete Midas-M Sensor Cartridge Package.

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).
