Mini Electronic PH Meter

A low cost but professional meter, enabling on the spot checks. pH range from 4-10 with an accuracy to 0.2 pH. Provided with a pH7 standard buffer solution.

We recommend that this is be used by professional gardeners and farmers when a high level of accuracy is required.  This meter has to be calibrated by using the buffer solution provided before it can be used.  A soil and water slurry needs to then be produced and the probe inserted into this mixture to get the pH reading.
