Cleaning Equipment
We recommend using sanitary cleaning wipes to wipe down the surfaces of the PHMU and the
PID prior to installing on a new participant.
Be sure to check the optical windows on each end of the PID before installing onto a new
participant. If the optical windows on the PID are not clean, use a thin cotton swab dipped in
rubbing alcohol to gently clean the window.
