4. Operation

4.5. pH calibration

To measure pH correctly, the electrode and the instrument set

need to be calibrated regularly with buffer solutions. This

compensates deviations of asymmetry potential and slope of the

electrode over time.

The calibration with buffer solutions corrects variations in the

electrode response.

The instrument allows one-, two- and three- point calibration.

The calibration parameters remain in memory until a new calibra-

tion is performed.

The standard calibration is performed with technical buffers and

standard stability criterion. In addition, the instrument offers

other options for calibration.

It is highly recommended to apply the same stability criteria to

measure and calibrate.

One-point calibration

This type of calibration is acceptable when measuring pH values

similar to those of the buffer solution.

It corrects the asymmetry potential of the electrode.

Two-point calibration

This is the most common calibration.

It is recommended to start with pH 7 as first buffer. pH 4 or pH 9

buffers can be used as a second buffer, depending on the meas-

ured zone (acid or alkaline).

The two-point calibration compensates the asymmetry potential

and the electrode’s sensitivity (slope).

Three-point calibration

This type of calibration is recommended when measurements are

made across the whole pH scale.

As a first point pH 7 is recommended.

For the second and third points, two of the remaining values

must be chosen.

The three-point calibration pH 4.00, 7.01 and 9.21 (at 25ºC,

77ºF) compensates the asymmetry potential and electrode’s

sensitivity in the acid and alkaline zone.

Calibration with technical buffers

Buffers pH 4.00, 7.01 and 9.21 (at 25ºC, 77ºC) are supplied

together with the instrument.

Preparation

Fill the flasks with the corresponding buffer solution (40 ml).

These buffers can be used to perform more than 10 calibrations.

Every calibration flask is supplied with a magnetic bar.

Diagram for calibration

Important note:

The pH value of the buffer appearing on the display depends on

the temperature of calibration. See buffers pH values as a func-

tion of the temperature on page 19.

To modify the

standard calibra-

tion see page 9.

User’s buffers

Suitable when the two above mentioned options will not be

used. The sensION+ MM340 allows introducing the

table pH/Temp. for the desired buffers. See System, page 17.

Calibration to X value

Manual re-adjustment of the measured pH at any value of the

scale. The pH readjustment is equivalent to calibration with only

one buffer.

Calibration data introduction

Manual introduction of calibration data for an electrode cali-

brated previously, for example in calibration laboratory.

Theoretical calibration

Selecting “theoretical calibration” the calibration data of the elec-

trode in use are replaced by the theoretical values at 25ºC (77ºF).

This step is prior to the obtention of a calibration certificate.

Calibration frequency

Select between 0 h and 7 days. The instrument by default is

programmed for daily calibration and indicates the remaining

time to the new calibration.

Selecting 0 h the automatic re-calibration warning is deactivated.

Stability criteria.

Rapid criterion (variation < 0.02 pH in 6 s).

Standard criterion (variation < 0.01 pH in 6 s).

Strict criterion (variation < 0.002 pH in 6 s).

It is highly recommended to apply the same stability criteria to

measure and calibrate.

Important note:

Once the calibration is

re-programmed, it will be

performed with the new

programming.

4. Operation

4.7. pH measurements

Measurement by stability

This is the default measuring mode for the

sensION™+MM340

Meanwhile the reading is in evolution, it appears on the display

momentaneously to orient the user. When the electrode signal

remains invariable during a certain period of time, the reading is

fixed on the display, the reading is stable.

Criterion of “rapid” stability: 0.02 pH (1 mV) in 6 seconds.

Criterion of “standard” stability: 0.01 pH (0.5 mV) in 6 s.

Criterion of “strict” stability: 0.002 pH (0.1 mV) in 6 seconds.

If in a certain time the reading is not stable, the instrument auto-

matically passes to continuous measurement (the measured

value is displayed all the time).

To select another stability criterion or to change measuring

parameters see “Measure re-programming”, page 11.

Magnetic stirrer: the instrument controls automatically the

start/stop of the stirrer.

Continuous measurement

The instrument displays the value obtained by the electrode all

the time. These data can be stored or printed with program-

mable interval of time. To select this type of measurement see

“Re-programming pH measurement”.

From the standard measuring mode (by stability), pressing twice

the key the measured value is shown on the display at any

moment but without option for data acquisition.

Measurement by time

The measurement is shown on the display after programmed

time. To select this measuring mode see “Re-programming pH

measurement”.

Manual samples coding

With

sensION™+MM340

it is possible to introduce a specific

code (maximum 15 characters) per each sample using an external

PC key board or bar code. See “System”, page 17.

Pressing twice, measure-

ment in continuous.

With connected temperature probe.

Important note:

Once the measurement has been re-programmed, it will be performed in

accordance with the new parameters.

It is highly recommended to apply the same stability criteria to measure and

4. Operation

4.10. mV measurement

The instrument factory configuration is:

Channel 1, pH.

Channel 2, ISE.

Anyone of the 2 channels can measure pH, mV or ISE.

The measurement units are selected in System.

Measurement conditions

Resolution: 1 mV / 0.1 mV

Measuring mode: By stability, In continuous or By time.

For more details, see “pH measurement”, page 10.

mV measurement with printer

See pH measurement with printer, page 12.

Important note:

Measuring mV the temperature is not shown. The temperature is

displayed only if a temperature probe is connected.

4. Operation

4.11. Measurement with ion selective electrode

Curve number 1

sensION™+MM340

can store in memory up to 4 calibration

curves for each channel.

Measurement by stability

It is the standard measurement mode of sensION+ MM340. See

details in “pH measurement”, page 10.

Criterion of “rapid” stability: variation < 0.5 mV in 6 s.

Criterion of “standard” stability: variation < 0.1 mV in 10 s.

Criterion of “strict” stability: variation < 0.05 mV in 10 s.

It is highly recommended to apply the same criteria to measure

and calibrate.

Measurement in continuous or by time

See details in “pH measurement”, page 10.

Note: Anyone of the 2 channels can measure pH, mV or ISE.

The measurement units are selected in System.

ISE measurement with printer

See pH measurement with printer in page 12.

ISE Calibration

Curve number

1 to 4: The

sensION™+MM340

can store in memory up to

4 calibration curves for each channel.

Stability criteria: see above “Measurement by stability”

It is highly recommended to apply the same criteria to measure

and calibrate.

Units

mol/l, M, g/l, mg/l, ppm, mmol/l, mM, µmol/l, %: Concentration

units of the calibration standards. The measurement will be

performed in the same units..

Name of the ion

5 characters to relate the curve with the ion to measure .

Number of standards: 2 to 5

Standards concentration

It is recommended to introduce the standard concentration in

increasing order, starting with the lower concentration. The

instrument will dispose them automatically.

Note: the instru-

ment will ask for the

standard with lowest

concentration.
