Use of a damp cloth is an acceptable method on exterior surfaces of the instrument. Special attention needs to be paid when cleaning the instrument so that moisture does not get onto the electronic circuit boards or into the internal sample path. There are certain disinfectant products that can be used. For more information, see the attached Cleaning Guidelines document. For information on cleaning and disinfecting your handheld Intoximeters instrument, see the Cleaning and Disinfecting document (updated March, 2020).
