Soil pH and Humidity Meter DM 15

SOIL PH & HUMIDITY METER DM15

* Specification:

- Soil pH measurement range: 3 - 8 pH

- pH resolution: ± 0.2 pH

- Humidity measuring range: 10 - 80%

- Humidity resolution: ± 5%

- Non-electric operation equipment

- Red storage box

* Usage:

- Measure the pH of soil to determine the concentration of Hydrogen ions for fertilizer and cultivation.

- Humidity should be measured before pH measurement 

* Manual instruction:

1. Measurement of soil moisture:

- Plug the probe so that the 3 metal rings of the probe are in the ground, press the white button. Read the humidity reading according to the needle on the screen (the scale below corresponds to 10 - 80% moisture)

2. Measure pH:

- Plug the probe into the ground similar to a moisture meter (do not press the white button). Read the pH value according to the pointer on the screen (the upper scale corresponds to 3 - 8 pH)

   + If the soil is dry or contains excessive amounts of organic fertilizer, the pH measurement results will not guarantee accuracy. So, before measuring, water the area and wait 20-30 minutes

    + Before measuring, you should peel off metal surface of machine probe with fine sandpaper. If the gauge is new, it must be plugged into the ground several times to clean the transducer oil.

   + Plug directly into the ground so that the soil wraps and sticks to the metal part of the probe to measure

   + About 1 minute after plugging the device into the ground, the indicator will stop deviating and be able to read the results

   + The machine can give different reading results for each measurement, it is due to the conditions such as: Adhesion of soil to metal probes, changing soil moisture, varying organic fertilizer content. ... Therefore, the average value of multiple measurements must be taken.

   + To ensure results need to measure the pH of the soil again after 1 or 2 weeks

- Note:

   + When measuring pH, the soil should be moist, soft, if dry, add a little water

   + After measuring, should clean all 3 metal rings of the probe to avoid stains. If there are stains, use sandpaper to clean it.

   + Do not allow water to contact the upper part of the body.
