Description
Honeywell Midas-M Phosphine (PH3) Sensor, 0-1200 ppb, 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 PH3) |
|---|---|---|---|
| Ammonia | NH3 | 50 | <380 |
| Arsine | AsH3 | 0.15 | 120 |
| Carbon Dioxide | CO2 | 5000 | 0 |
| Carbon Monoxide | CO | 85 | 0 |
| Chlorine | Cl2 | 0.85 | <-50 |
| Diborane | B2H6 | 0.2 | 10 |
| Hydrocarbons | CH4 | 18000 | 0 |
| Hydrogen | H2 | 3100 | <50 |
| Hydrogen Chloride | HCl | 7.9 | 0 |
