Honeywell MIDAS Sensor Cartridge for Chlorine (Cl2) 0.18-2 ppm, Fluorine (F2) 0.18-2 ppm



Honeywell MIDAS Sensor Cartridge for Chlorine (Cl2) 0.18-2 ppm, Fluorine (F2) 0.18-2 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.

Other Detectable GasesThe following additional gases can be detected with this sensor cartridge. Sensor performance and characteristics will be representative of the data as tabulated above. Consult the Technical Manual to set up the Midas transmitter with the designated identification code for each of the following gas types.
Detectable GasChemical FormulaMeasuring Range
FluorineF20-4 ppm
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).
Gas / VaporChemical FormulaConcentration Applied (ppm)Reading (ppm CI2)
Carbon MonoxideCO200000
Hydrogen ChlorideHCl91.25
Hydrogen SulfideH2S 25-16.3
Nitrogen DioxideNO2501.25 (transient)
Sulfur DioxideSO2509.1
