MAINTENANCE
SECTION 11.0
MAINTENANCE
11.1 OVERVIEW
This section gives general procedures for routine maintenance of the 6081-P pH/ORP transmitter and pH and
ORP sensors. The transmitter needs almost no routine maintenance. Sensors require periodic inspection and
cleaning. The calibration of the transmitter-sensor combination should be checked regularly, and the loop recali-
brated if necessary.
11.2 TRANSMITTER MAINTENANCE
Periodically clean the transmitter window and housing as needed with a cloth dampened with water. Do not use
abrasive cleaning solutions. The O-rings and sealing surfaces must be kept clean or moisture may enter the
electronic enclosure.
