WARNING

Pressure and temperature

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.

Do not insert or retract retractable sensors when process pressures are in excess of 64 psig (5.4
barg) for option 21 or 35 psig (3.4 barg) for option 25.

WARNING

Corrosive substance

The solution used during calibration is an acid; handle it with care.
Follow the directions of the acid manufacturer.
Wear the proper protective equipment.
Do not let the solution come into contact with skin or clothing.
If contact with skin is made, immediately rinse with clean water.

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.

CAUTION

Special conditions for safe use

All pH/ORP sensors have a plastic enclosure which must be cleaned with a damp cloth to avoid the
danger due to a buildup of electrostatic discharge.

CAUTION

2 Calibration and maintainenance

2.1 Calibrate pH two point buffer

Prerequisites

Select two stable buffer solutions, preferably pH 4.0 and 7.0 (pH buffers
other than pH 4.0 and pH 7.0 can be used as long as the pH values are at
least two pH units apart).

NOTICE

A pH 7 buffer solution reads an mV value of approximately zero, and pH
buffers read approximately ±59.1 mV for each unit above or below pH 7.
Check the pH buffer manufacturer specifications for millivolt values at
various temperatures since it may affect the actual value of the buffer
solution mV/pH value.

Procedure

1. Immerse sensor in the first buffer solution. Allow sensor to
equilibrate to the buffer temperature (to avoid errors due to
temperature differences between the buffer solution and sensor
temperature) and wait for reading to stabilize.
The transmitter can now acknowledge the value of the buffer.

2. Once the transmitter has acknowledged the first buffer, rinse the
buffer solution off the sensor with distilled or deionized water.

3. Repeat Step 1 and Step 2 using the second buffer solution.

The theoretical slope value, according to the Nernst equation for calculating
pH, is approximately 59.1 mV/pH. Over time, the sensor will age, both in the
process and in storage, which will result in reduced slope values. To ensure
accurate readings, Emerson recommends that you replace the electrode
when the slope value falls below 47 to 49 mV/pH.

2.2

Recommended pH standardization

For maximum accuracy, standardize the sensor on-line or with a process
grab sample after performing a buffer calibration and conditioning the
sensor to the process.

Standardization accounts for the sensor junction potential and other
interferences. Standardization will not change the sensor's slope, but will
simply adjust the transmitter's reading to match that of the known process
pH.

Quick Start Guide 21

Quick Start Guide August 2021

2.3 Maintain pH electrodes

Electrodes should respond rapidly. Sluggishness, offsets, and erratic
readings are indicators that the electrodes may need cleaning or
replacement.

1. To remove oil deposits, clean the electrodes with a mild non-abrasive
detergent.

2. To remove scale deposits, soak electrodes for one to five minutes in a
five percent hydrochloric acid solution.

WARNING

Corrosive substance

Hydrochloric acid is toxic and highly corrosive.

Avoid skin contact.
Wear protective gloves.
Use only in a well-ventilated area.
Do not inhale fumes.
In case of an accident, consult a doctor immediately.

3. Temperature effect on life expectancy: If glass electrode life
expectancy is 100 percent at 77 °F (25 °C), then it will be
approximately 25 percent at 176 °F (80 °C), and approximately 10
percent at 212 °F (100 °C).

2.4

22 Emerson.com/Rosemount

Calibrate oxidation reduction potential (ORP)

Prerequisites

After making an electrical connection between the sensor and the
transmitter, obtain a standard solution of saturated quinhydrone
PN R508-8OZ (460 ± 10 mV). You can also make the solution by simply
adding a few crystals of quinhydrone to either pH 4 or pH 7 buffer.
Quinhydrone is only slightly soluble; therefore only a few crystals are
required.

Procedure

1. Immerse the sensor in the standard solution. Allow one to two
minutes for the ORP sensor to stabilize.

August 2021 Quick Start Guide

2. Standardize the transmitter to the solution value shown in Table 2-1.
The resulting potentials, measured with a clean platinum electrode

and saturated KCl/AgCl reference electrode, should be within
±20 mV of the value shown in Table 2-1. Note solution temperature
to ensure accurate interpretation of results. The ORP value of
saturated quinhydrone solution is not stable over long periods of
time. Therefore, make these standards fresh each time they are used.

Table 2-1: ORP of Saturated Quinhydrone Solution (Millivolts)

pH 4 solution pH 7 solution

68 (20) 77 (25) 86 (30) 68 (20) 77 (25) 86 (30)

3. Remove the sensor from the buffer, rinse, and install in the process.

2.5 Maintain oxidation reduction potential (ORP) sensors

Electrodes should respond rapidly. Sluggishness, offsets, and erratic
readings are indicators that the electrodes may need to be cleaned or
replaced.

1. To remove oil deposits, clean the electrode with a mild non-abrasive
detergent.

2. To remove scale deposits, soak electrodes for one to five minutes in a
5 percent hydrochloric acid solution.

3. Polish ORP (metallic) electrodes with moistened baking soda.

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.
