Unique, dual-purpose Kelway Field Testing Meter gives accurate soil pH
(3.5—8.0 range) and moisture (0—100% relative saturation) measurements in
three minutes or less. Simply insert pointed end to achieve good soil contact.
Readings from scales on top dial are based on measured electrical potential
between two dissimilar metal plates. No batteries, electrodes, or buffer solutions
are needed, and the meter is durable and insensitive to normal temperatures.
Meter is supplied complete with belt-loop carrying case, two 3x4in (76x102mm)
conditioning film sheets, and instructions. Conditioning film is used to clean
electrode plates prior to use. Not for use with liquids. Meter is 6.5in (165mm) long
with 1.5in (38mm) diameter dial; net wt. is 8oz (0.2kg). Est. Ship Wt.: 2lb (1kg).
