Lutron Soil PH and Moisture Meter (PH-220S)

Display 20 x 28mm.
Measurement range 0 to 14 pH x 0.01pH.
Resolution 0.01 pH.
Accuracy ± 0.07 pH (pH 5 to pH9).

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 the 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.
