Designed for quick and easy moisture testing, the Dole 400 is a popular on-farm, portable moisture tester. Unit operates on a 9-Volt transistor battery (not included). The optional AC/DC converter is available for fixed or permanent test locations.

This Seedburo unit comes complete with a built-in sample weighing scale and temperature/moisture correction indicator. Moisture percentages of popular grains are read directly off of the dial without the need of conversion charts. Many other commodities can be tested using conversion charts that are supplied with each tester. Quick results are achieved using the capacitance testing method.
