Manual for the Electronic Meter "FT 20"
pH Temp. RH
0.00 - 14.00 0 - 50°C 10 - 99%
Thank you for purchasing our “FT 20" pH - Temperature - RH meter.
All pH-readings are automatically temperature compensated (ATC). Measurements are
highly accurate.

pH-Calibration:
1) Remove the protective cap.
2) Switch the meter on by folding back the electrode
(automatic switch on/off).
3) Immerse the electrode in a buffer solution “pH 7.00".
5) Stir gently and wait for the reading to stabilize.
6) Use the screw-driver to adjust the reading to “7.00",
screwing at the screw marked “STAND“.
7) Rinse the electrode with water.
8) Replace the protective cap and switch the meter off.
Calibrate when:
• The electrode has not been used for a while
• The utmost accuracy is required
• The electrode has been used in particularly taxing conditions
Changing Battery:
1) Open the battery
compartment
on the back side
2) Remove the used
batteries
3) Place new batteries
4 x 1.5 V (AG-13)
and use caution to
the position of the
poles
4) Close the battery
compartment
Operation:
1) Remove the protective cap and switch the meter on by
folding back the electrode (automatic on/off).
2) Make sure, that the holes on the back side of the meter are
not covered during the test procedure.
3) Immerse the electrodes in the solution to be tested.
4) Stir gently and wait for the reading to stabilize.
5) Read the result, than rinse the electrodes with water.
6) Replace the protective cap and switch the meter off.
