Description
Honeywell MIDAS Sensor Cartridge for Diborane (B2H6) 0.036-0.4 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 B2H6) |
|---|---|---|---|
| Ammonia | NH3 | 108 | <0.1 |
| Arsine | AsH3 | 0.2 | 0.1 |
| Carbon Dioxide | CO2 | 5,000 | 0 |
| Carbon Monoxide | CO | 85 | 0 |
| Chlorine | Cl2 | 0.85 | -0.15 |
