Specific Conditions for Safe Use (X):
1. All pH/ORP sensor models with a plastic enclosure or exposed plastic
parts may provide an electrostatic ignition hazard and must only be
cleaned with a damp cloth to avoid the danger of ignition due to
build-up of electrostatic charge.
2. All pH/ORP sensor models with a metallic enclosure may provide a
risk of ignition by impact or friction. Care should be taken during
installation to protect the sensor from the risk.
3. External connections to the sensor must be suitably terminated and
provide a degree of protection of at least IP20.
4. All pH/ORP sensor models are intended to be in contact with the
process fluid and may not meet the 500V r.m.s. test to earth. This
must be taken into consideration at installation.
