Please refer to the interface drawings of your probe and mounting system for further guidance.

To ensure success with installs, it is important to consider the following requirements:
•
The IRmadillo needs to be suitably supported. The weight of the instrument is ~18 kg,
and it must be supported using the mounting points at the base, either through a
custom stand or using a Keit Cradle. The probe should not be used to support the
instrument.
•
The body of the IRmadillo should not be placed in direct sunlight or near a heat source.
The instrument has internal temperature control, but this rating is limited and model
dependant. Direct heat sources can force the instrument beyond its operating range
and cause damage.
•
The IRmadillo must be axially restrained when in the flow. Pressure on the probe will
cause the system to move if not properly restrained along the probe’s axis.
•
It is preferable to mount the IRmadillo with the probe positioned horizontally. Mounting
the IRmadillo with the probe pointing downwards risks the formation of bubbles on the
ATR element, and prevents the ATR from coming into full contact with the analyte to
correctly analyse the process liquid.
•
Similarly, avoid mounting the IRmadillo with the probe pointing upwards. If there are
any suspended solids in the mixture, there is a risk of these solids settling on the probe
tip, which may result in the spectra not being representative of the process liquid.
•
The IRmadillo must be exposed to the flow when in operation. The probe tip must be
positioned in the flow within the pipeline or vessel to perform correctly; turbulent flow
is desired. If the tip is held in stagnant chemistry, building representative chemometric
models will not be possible.

•
The probe must be aligned correctly with the port in which it is placed. It should not be
forced or bent into place as this will cause damage to the instrument.
•
The IRmadillo body should not be placed directly in caustic or acidic environments.
The body is made from aluminium and will break down.
