1. FEATURES
Simply inserting the probe in the hay, dried or stored, allows this instrument to display moisture content
in % by utilizing the electric resistance measurement. Very handy to use and easy to operate, it allows
you to measure hay wherever and whenever you want to.
Damp hay in storage is apt to ferment or rot, and over drying will reduce the quality. The weight fluctua-
tion of the hay due to water content is an important issue in business transactions.

the advantages offered to you by the HX-700, whether for moisture control during storage or to check
moisture during a buying or selling transaction.
