INTRODUCTION

These Sper Scientific Test Tube pH Pens (Models

SP-850062/ 63 / 65 / 66 / 67) are designed for easy

calibration and simple, accurate measurement.

The 12 cm long probe is capable of testing

samples even in narrow-mouthed containers.

The waterproof meter provides one-button,

automatic three-point calibration. Calibration is

also possible within± 0.5 pH units of 4, 7, and

10. Other features include a data-hold function,

automatic shutoff andlow-battery indicator.

Models SP-850063 / 65 / 66 / 67 also measure

temperature and provide automatic temperature

compensation.

STANDARD CALIBRATION

The meter should be calibrated regularly with

standard USA, NIST or DIN buffers to ensure

accuracy. If the meter is used frequently, daily

calibrationisrecommended.

Voltage Range for Each Calibration Point

pH 4 00 97 mV to 250 mV

pH 7 00 -60 mV to 60 mV

pH 10 00 -250 mV to -97 mV

Calibration Procedure

1 PressPOWER buttontoturnthemeter on

2. Pour the pH buffer into a clean container

and place the electrode into the buffer. We

recommendstartingwithamiddlerange

buffer such as pH 7. Make sure the electrode is

completelyimmersedinthebuffer.

3 PressCAL toenterCalibrationMode.

“CAL”displays for one second, followed by the

7. Repeat steps 2-5 for the pH 4 and 10

buffers.

CUSTOM CALIBRATION

During calibration mode, you can adjust the

buffer values to non-standard values. For

example,

4.00pHmaybeadjusted from

3.50 to 4.50.

7.00pHmaybeadjusted from

6.50 to 7.50.

10.00 pHmay beadjusted from

9.50 to 10.50.

1.Place the electrode inthe non-standard

buffer and press the CAL button. The meter

will display 4, 7, or 10 depending on which

is closest.

2.Pressandhold the Hold button.The

number on the screen will begin to change in a

positivedirection. 6

3. Continuetopresstheholdbuttonuntilyour

4. Onceyou have selectedthe desired buffer

value, releasethe holdbutton and wait

5. "End" displays and the meter returns to

NormalMode.

6. Rinse the probe with deionized water, a

rinse solution,ortap water.

7. Repeat steps 2-7 to calibrate the meter with

MEASUREMENT PROCEDURES

Note…

The electrode should besoakedfor atleast
