The Highest Concentration Range is the highest range the sensor is suitable. The Lowest Concentration Range is the lowest range the sensor is
suitable. The use of the sensor beyond these ranges will affect the sensor’s performance.
IR15TT
The IR15TT can be used in all applications for general monitoring of both relatively low concentrations of carbon dioxide and
simultaneous %LEL and %v/v concentrations of Group II hydrocarbons, including benzene. The sensors contain a broadband
hydrocarbon detector which are cross sensitive to most hydrocarbons and can therefore be calibrated to a specific target gas or
a number of gases that can then be selected in the configuration of the customer’s gas measurement instrument.
IR15TT-M
The IR15TT-M is very similar to the IR15TT except that a narrowband hydrocarbon detector is used. The sensor can still be
used to monitor the same levels of carbon dioxide and hydrocarbons but are unsuitable for the detection of benzene. The
narrowband detector also has a slightly lower response to humidity than the IR15TT, but is generally more cross-sensitive to
other hydrocarbons.
IR15TT-R
The IR15TT-R was designed specifically for Biogas applications for the simultaneous detection of carbon dioxide up to 100%v/v
and %LEL and %v/v concentrations of hydrocarbons, but can be potentially used for other applications. The IR15TT-R contains
the narrowband detector which is unsuitable for the detection of benzene.
IR15TT-D
The IR15TT-D is fitted with both the narrowband and broadband hydrocarbon detectors with differing centre wavelength and
bandwidth to potentially differentiate between hydrocarbons. The sensor was designed for the gas instruments being used by
utilities companies to help differentiate between different compositions of natural gas.
HANDLING PRECAUTIONS
1. Do not allow sensors to fall on the floor. This could cause IR Source filament breakage, damage to the pins and the gas
entrance aperture.
2. Do not apply mechanical force against the gas entrance aperture.
3. Do not immerse sensors in water or other fluids.
4. Protect the gas entrance aperture against dust ingress and sprayed materials.
5. Anti-static handling precautions must be taken.
