Description
Honeywell Midas-M Ozone (O3) Sensor, 0-0.4 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 O3 sensor CANNOT be combined with an SO2 sensor in a complete Midas-M Sensor Cartridge Package.

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 O3) |
|---|---|---|---|
| Ammonia | NH3 | 100 | -3 |
| Arsine | AsH3 | 0.2 | 0 |
| Carbon Dioxide | CO2 | 5000 | 0 |
| Carbon Monoxide | CO | 100 | 0 |
| Chlorine | Cl2 | 1 | 1.2 |
| Chlorine Dioxide | ClO2 | 1 | 1.5 |
| Chlorine Trifluoride | ClF3 | 1 | 1 (Theoretical) |
| Fluorine | F2 | 0.1 | 0.1 |
