About this product

The Lutron PH-220S is designed for measuring pH in soil. It consists of a handheld digital meter with LCD screen and a spear tip probe on a 750mm cable. This probe has a durable glass measuring spear which is contained in a rugged epoxy body. It is ideal for measurement of both soil and other semi-solid substances.

This meter has a measurement range of 1 to 13 pH with a resolution of 0.01 pH.

The PH-220S is powered by one AAA battery (included). pH 4 / pH 7 buffer solutions and a user manual are also supplied. 

NB: For best results the measurement substrate should be mixed to a smooth slurry. Dibber not included.
