Impact Pro Sensor Cartridge with Infrared Sensor
All IR sensor cartridges require a modified Impact Pro IR cartridge bay, which is designated as modification state 15.
If not present, this modification must be performed by your authorised Honeywell Analytics Service Center. Failure to do this may lead to physical damage when attempting to insert the new IR sensor cartridge and will not be covered by warranty.
Any electrochemical sensors in this cartridge cannot operate accurately in Oxygen deficient environments and should not be used for continuous monitoring in inert atmospheres. Infrared sensors for flammable gases cannot detect Hydrogen (H2). If the environment is suspected of containing combustible levels of Hydrogen, a cartridge that uses a standard catalytic bead sensor should be used with the Impact Pro instead.
The flammable (%LEL or % V/V) IR sensors are factory calibrated to respond linearly to Methane (CH4).
Response to other hydrocarbons is non-linear and the Impact Pro IR will not display corrected values for other hydrocarbon gases. The Impact Pro IR will generally (but not always) give a higher reading for heavy hydrocarbons than for Methane.
