- Will automatically re-calibrate itself at the touch of a button when used in conjunction with a 7.00 pH buffer solution
- Powers off automatically after 10 minutes
- Powered by 4 x LR44 button cell batters (supplied)
- Includes a protective cap
A hand-held pH meter is an inexpensive alternative to larger meters and very much more accurate and reliable than litmus paper.
NB Must be regularly calibrated using pH 7 buffer solution (sachet to make up 100ml of pH 7 buffer solution supplied with meter)
NB When you run out of buffer solution, you can order Buffer Capsules (pack of 10) - part code 94214.
NB We also supply a pH and Temperature Meter Kit - part no 94282
Please see the Test Equipment category in Catalogue for our full range of test equipment.
NB: Regular calibrating, cleaning and storage of this pH meter will prolong its life.As with all pH meters, the electrodes on them have a limited lifespan. The manufacturer's state: 'This pH meter can accurately measure 365 tests for one year (based on one test per day) if the sensor is maintained. After this time the sensor will degrade, but regular cleaning and calibration of the unit will prolong its life past the expected amount of tests.' If you require a pH meter with a longer lifespan (and the option of replaceable electrodes) please see the alternative model we supply (pH and Temperature Meter Kit - part no 94282).
