The Lutron PH-212 Soil pH Meter comes with a pH electrode, pH 4.0 and pH 7.0 buffer solutions and a plastic carrying case. The included spear tip electrode is ideal for measurement of soils as well as other semi-soft materials which require sample penetration. The electrode features a durable glass measuring spear packaged in a rugged epoxy body. The hand held meter has a large LCD display with easy to use push buttons and is powered by a 9V battery (not included).
NB: For best results the measurement substrate should be mixed to a smooth slurry. Dibber not included.
