Most conventional moisture testers utilizing the electrical measurement method are designed for one
specific application as their product names suggest, such as Wood Moisture tester or Grain Moisture
tester. This is because their calibrations are pre-set to measure a certain subject. They are handy because
they are ready to be used immediately after purchase, but naturally you can't expect accuracy measuring
other subjects. You have to have many different moisture testers to measure a range of subjects. For
example, for processed food you may not have been able to nd a suitable moisture tester and had to rely
on the time consuming Dry Process Method to know the moisture content. The market was waiting for one
handy electric moisture tester able to measure various kinds of samples in dierent conditions and shapes.
HB-300 can measure the moisture of many kinds of samples in various conditions and shapes such as
solid, powder, grains, paste, sheet, etc. You can make the calibration for your samples relatively easily
and register it to the tester. Many optional sensor probes are available for the HB-300 which further
amplify the range of measurement subjects.
