Tough Process Spectrometers

Keit IRmadillo25 FTIR Spectrometer

The IRmadillo family of FTIR spectrometers are tough instruments certified for use in hazardous and potentially explosive environments. Mounted directly on, or in-line with, manufacturing vessels, the instruments excel at continuous monitoring of industrial and bio-industrial liquids and slurries.

Faster Results as They Happen

No need to wait for your results. With an in situ sensor to monitor your reactions live, the Keit IRmadillo tells you what your reactions are doing as they happen, rather than after they happen — and where ever they happen.  No more waiting for your analysis results from remote sampling techniques such as with HPLC or GC.

Key Qualities & Rugged Components

  • Mid-infrared spectral analysis
  • Hastelloy or stainless steel probe material
  • ATR probe (diamond option)
  • Certified safe for use in hazardous and potentially explosive environments
  • Compact and rugged
  • Low maintenance
  • Clean in place (CIP) and sterilise in place (SIP) compatible (IRmadilloDiamond only)

Innovation in Process Monitoring & Control

Standard FTIR analytical instruments are highly sensitive to vibration and ambient temperature— making them a challenge to use outside or on the manufacturing floor.  Keit offers an innovative solution for continuous monitoring of your processes in real-time over a variety of industrial applications – from detecting the quantity of water in glycol at a petrochemical plant to measuring sugars and alcohol in an industrial fermentation vat.

The IRmadillo Family of Spectrometers


IRmadillo25 is the Ex-certified original model. With a probe diameter of 25mm, the IRmadillo25 has infrared-glass ATR and is the go-to instrument for real-time analyses of liquids for better process monitoring and control.


As the diamond-ATR model in the IRmadillo family, it inherently tolerates a wider range of pH (0 to 14) and more caustic materials than the IRmadillo25. The diamond version’s distinguishing feature is a wider probe diameter (38 mm) and ability to remain in place for clean-in-place (CIP) and sterilise-in-place (SIP) processes.
