Description
Honeywell MIDAS Sensor Cartridge for Hydrogen (H2) 90-1000 ppm
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 (ppm H2) |
|---|---|---|---|
| Ammonia | NH3 | 100 | 0 |
| Arsine | AsH3 | 0.2 | 0 |
| Carbon Dioxide | CO2 | 1000 | 0 |
| Carbon Monoxide | CO | 100 | 150 |
| Chlorine | Cl2 | 1 | 0 |
| Chlorine Dioxide | ClO2 | 1 | 0 |
| Hydrogen Cyanide | HCN | 20 | 0 |
| Hydrogen Sulfide | H2S | 20 | 4 |
| Iso Propanol | C3H7OH | 1100 | Yes |
