7 Maintenance and repairs
44 NIRMaster Operation Manual, Version B
7 .2 .1 Housing
Clean the housing with a soft, lint free damp cloth with mild soapy water. For hygienic reasons, use
surface disinfectant wipes in combination with similar disinfectant spray on alcohol basis. If the sample
window on top of the instrument is dirty, clean it with an antimicrobial wipe (e.g. Melisptol® wipes).
In order to avoid contamination by sample material between the measurements, clean the surfaces in
direct contact with the sample after each measurement.
NOTE
• Switch off the NIRMaster and all directly connected eletronic devices i.e. monitors before cleaning
the housing.
• Never use any objects for cleaning which might scratch the optical surfaces or add-ons of the
NIRMaster. Scratches can influence a measurement!
• For coated optical surfaces, use abrasion-resistant precision cloths such as Kimwipes from
Kimberly-Clark. Primary cleaning can be done with disinfectant wipes on alcohol basis.
• Do not clean coated optical surfaces in a washer.
• Avoid fingerprints on any optical surface!
