The wetted sensor materials may not be compatible with process composition and operating
conditions. Application compatibility is entirely the responsibility of the user.
WARNING
Before removing the sensor, be absolutely certain that the process pressure is reduced to 0 psig and
the process temperature is lowered to a safe level!
