4.  COMPONENTS 

This  section  contains  general  information  about  the  IRmadillo  spectrometer,  such  as  the 
constituent components and internal controller specifications. 

4.1.  IRmadillo spectrometer 

 

Figure 15: ASM0627-10-Z-Cx-Ex-Gx-D3x front and top of the instrument  

(A) Product label 

The  product  label  specifies  the  model  of  instrument  with  permissible  environmental  and 
analyte operating conditions, along with applicable certification. Particular attention should be 
given to the rated pressure and temperature limits. 

(B) ATR element  

The diamond ATR element is located at the end of the probe.  

(C) Probe

 

The probe is designed to be installed directly into a reaction vessel or pipe and is made of a 
corrosion-resistant metal.   

(D) Probe (gas) purge outlet 

Allows purge gas to escape the probe. There is a single outlet  located on the probe for all 
purge gas to escape.
