Features :
  1. If the soil to be tested is dry or contains much manure, the meter will not indicate a
      correct pH value. Therefore, sprinkle about a bucketful of water on the soil, and wait
      20-30 minutes, before testing.
  2. Before using the meter, be sure to thoroughly polish its metallic surface with a piece
      of whetting cloth or sandpaper. When using a brand-new meter,be sure to insert it into
      the soil a few times in order to remove the oily impurities from its metallic surface.
  3. Insert the meter directly into the field or paddy soil under consideration. Completely
      embed the metallic surface and tamp down the surrounding soil so that it adheres
      closely to the meter’s metallic electrode surface.
  4. About one minute after inserting the meter in the soil, the pointer will cease to
      deflect— the pH value of the soil may then be read.
  5. The meter may sometimes register different values depending on the soil
      condition--such as, adhesion to the meter’s metallic surface, moisture content,or the
      amount of manure it contains. It is therefore ideal to take an average of several
      measurements.
  6. In order to determent whether or not limiting has been properly done, after one or two
      weeks mix the soil well and measure its pH value.

HOW TO USE THE DM-15, either as a pH or moisture meter.
 When the DM-15 is inserted in the soil with the white button on its side left un-depressed,
 it works as an acidity (pH value) meter.When the white button is depressed after it has been
 inserted in the soil, it works as a moisture meter.

HOW TO USE THE DM-15, as a moisture meter.
 Soil moisture control is extreme importance. Soil moisture is usually expressed in units
 termed pH, a generally unfamiliar term to people who cultivate.However,  Takemura’s
 tester, which combines a pH with moisture meter, is easy to use—soil  moisture can be
 determined at a single glance.

1. Insert the meter’s metallic electrode in the soil completely, while positioning the electrode
    as near crop roots as possible.
2. Scale divisions range from 1 to 8, each of which reads the moisture value accordingly to
    soil condition.
3. The need for water can be determined by the position of the pointer.
