MAINTENANCE AND RECALIBRATION

Blocking of the optical path between the target and detector can cause low readings. Occasionally, accumulated
materials on the diffuser of the SU-200 series UV-A sensors can block the optical path in three common ways:
1. Moisture or debris build-up on the diffuser.
2. Dust during periods of low rainfall.
3. Salt deposit accumulation from evaporation of sea spray or sprinkler irrigation water.
SU-200 series sensors have a domed diffuser and housing for improved self-cleaning from rainfall but active
cleaning may be necessary. Dust or organic deposits are best removed using water, or window cleaner, and a soft
cloth or cotton swab. Salt deposits should be dissolved with vinegar and removed with a cloth or cotton swab.
Never use solvents such as alcohol or acetone to clean the sensor. Use only gentle pressure when cleaning the
diffuser with a cotton swab or soft cloth, to avoid scratching the outer surface. The vinegar should be allowed to
do the cleaning, not mechanical force. Never use an abrasive material or cleaner on the diffuser.
It is recommended that UV-A sensors be recalibrated every two years. See the Apogee webpage for details
regarding return of sensors for recalibration
