• High pH glass provides greater accuracy over 12.5 pH
• HF glass provides improved resistance to hydrofluoric acid up to
300 ppm
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!

CAUTION
SENSOR/PROCESS APPLICATION COMPATIBILITY
The wetted sensor materials may not be compatible
with process com position and operating conditions.
Application compat ibility is entirely the responsi-
bility of the user.
CAUTION
The solution used during calibration is an acid and
should be handled with care. Follow the directions of
the acid manufacturer. Wear the proper protective
equipment. Do not let the solution come in contact
with skin or clothing. If contact with skin is made,
immediately rinse with clean water.
ATEX DIRECTIVE
Special Conditions for safe use
1. All pH/ORP sensors have a plastic enclosure
which must only be cleaned with a damp cloth to
avoid the danger due to a build up of an electro-
static charge.
2. All pH/ORP sensor Models are intended to be in
contact with the process fluid and may not meet
the 500V r.m.s. a.c. test to earth. This must be
taken into consideration at installation.
