Dissolved Ozone Sensor

Safety information
CAUTION
Sensor/process application compatibility
The wetted sensor materials may not be compatible with process composition and operating
conditions.
Application compatibility is entirely the operator's responsibility.
CAUTION
Equipment damage
Do not exceed pressure and temperature specifications
Pressure: 65 psig (549 kPa abs) max.
Temperature: 32 to 122 °F (0 to 50 °C)
WARNING
Physical access
Unauthorized personnel may potentially cause significant damage to and/or misconfiguration of
end users’ equipment. This could be intentional or unintentional and needs to be protected against.
Physical security is an important part of any security program and fundamental to protecting your
system. Restrict physical access by unauthorized personnel to protect end users’ assets. This is true
for all systems used within the facility.
