Description
Honeywell Midas-M Carbon Monoxide (CO) Sensor, 0-100 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.

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).
| Gas / Vapor | Chemical Formula | Concentration applied (ppm) | Reading (ppm CO) |
|---|---|---|---|
| Acetone | (CH3)2CO | 1000 | 0 |
| Acetylene | C2H2 | 40 | 80 |
| Ammonia | NH3 | 100 | 0 |
| Chlorine | Cl2 | 2 | 0 |
| Ethanol | C2H5OH | 2000 | 3 |
| Ethylene | C2H4 | 100 | 110 |
| Hydrogen | H2 | 100 | 35 |
| Hydrogen Sulfide | H2S | 25 | 0 |
| Iso Propanol | C3H7OH | 200 | 0 |
| Nitric Oxide | NO | 50 | 8 |
| Nitrogen Dioxide | NO2 | 800 | 20 |
| Sulfur Dioxide | SO2 | 50 | 0.5 |
