pH AND ORP PROBES
INSTRUCTION MANUAL
1.0 GENERAL INFORMATION
This manual covers all AquaMetrix P/R575 and P/R585 Series conventional combination pH and
ORP probes.
All mounting configurations are described.
Consult factory before using the sensor in extremely strong solvents such as ethylene dichloride.
Before placing the sensor into operation, remove the protective plastic cap. Store this cap for future
use.
NOTE: If the sensor is removed from the process for an extended period of time, thoroughly clean
the sensor, put a piece of cotton ball with few drops of water into the protective cap and
replace it on the sensor. This keeps the junction from drying out which causes slow
response when put back into operation or causes permanent damage to the sensor.
Sensors should not be left in dry lines or empty tanks for extended periods.
Do not store the sensors in a dry or humid location. When storing, check the protective cap
regularly to make sure the cotton ball remains moist. Improper storage of sensors voids the
warranty.
