Description
Honeywell MIDAS Sensor Cartridge for Oxygen (O2) 0.2-25% v/v, 3 year warranty
Several Honeywell MIDAS® cartridges can be configured to read a number of different gases based on a common chemical family. Actual details for the sensor detection range are included in the sensor cartridge specification sheet and the MIDAS® technical manual. MIDAS® sensor cartridges can be ordered as part of a Kit with the universal MIDAS® transmitter, or as a replacement part. The detectable range is listed. With the exception of O2 (where ambient concentration is typically 20.9%), the sensors will display zero when no gas is present. All Cartridges with the format MIDAS-E-XXX are supplied with a 2 year (24 month) warranty.

Each Midas 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).
| Gas / Vapor | Chemical Formula | Concentration applied (ppm) | Reading (% O2) |
|---|---|---|---|
| Carbon Dioxide | CO2 | Enhance O2 reading by 0.3% / % CO2 | |
| Hydrogen | H2 | 100% v/v | -9 |
| Methane | CH4 | 100% v/v | No response |
| Nitrogen Dioxide | NO2 | 25 ppm in air | No response |
