Faithfull pH Meter Probe for Soil

For checking soil pH, the Faithfull pH Meter Probe for Soil is an analogue meter that measures acidity and alkalinity. Its needle display shows the acid-alkaline range, and readings are provided in 60 seconds without batteries.

It can be used to test soil conditions before planting and for fruit and vegetable cultivation. To raise pH, the text names ground agricultural limestone, burnt lime or hydrated lime. To lower pH and increase acidity, it names aluminium sulphate or sulphur; aluminium sulphate acts immediately upon dissolving into the soil.
