Honeywell MIDAS Sensor Cartridge for Carbon Dioxide ECC cartridge 0.15-2.00 % v/v



Honeywell MIDAS Sensor Cartridge for Carbon Dioxide ECC cartridge 0.15-2.00 % v/v

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.

Cross Sensitivities

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).

Carbon MonoxideCO500< 0.05
ChlorineCl22< 0.05
HydrogenH21000< 0.05
Hydrogen SulfideH2S75< 0.05
MethaneCH420000< 0.05
Nitrogen DioxideNO250< 0.05
Sulfur DioxideSO250< 0.05
