Moisture content testing from 5% to 30% in a simpler way. This hand-held meter features twin probes which are simply inserted into the hay orgrain pile. The instrument can be set for a variety of grain types, and will read temperatures as well as moisture content. A standard figure can be set so that the meter then gives an audible warning for readings over the standard. Probes 30cm long, can be de-coupled from the meter. Powered by 3 x AAA batteries (supplied). Weight 200gm.
