Description
Honeywell Midas-M Ammonia (NH3) 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.
Note: The NH3 sensor CANNOT be combined with an HCl, Cl2, or HF 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 NH3) |
|---|---|---|---|
| Arsine | AsH3 | 0.2 | 0.07 |
| Carbon Dioxide | CO2 | 5000 | 0 |
| Carbon Monoxide | CO | 100 | 0 |
| Chlorine | Cl2 | 1 | 0 |
| Ethanol | C2H5OH | 1000 | 0 |
| Hydrogen | H2 | 10000 | 0 |
| Hydrogen Chloride | HCl | 10 | -4 |
| Hydrogen Sulfide | H2S | 20 | 2 |
