- Technical Specifications
- Tests soil in 3 ~ 10 minutes, no battery or chemicals,
- Length: 16.3 cm( 6.4 ")
- Weight: 100 grams( 3.2 oz).
- pH range from 3.5 to 8.
- Moisture: 1 to 8 Used for testing soil not liquids.
- pH-707 Description
- Soil Acidity tester, pocket size soil tester needs no batteries or chemicals, simply insert in soil for instant reading. Push button switch for measuring moisture.
- List of Optimum pH Index for some farm products:
- pH 5~6 : Rosebay, Lily of the valley, azalea, rose.
- pH 5~6.5 : Rice-plant, potato, foxtail millet, corn, peppermint, radish.
- pH 6~8 : Spinach, kidney bean, lettuce, onion, cucumber, carrot, tomatto, turnip, egg plant, celery, burdock, cabbage, chrysanthmum, dahlia, narcissus, tulip, carnation.
- pH 7~8 : barley, wheat, rye, suggar beat, pea, clover, alfalfa, garden zinnia.
- Q & A :
- What's the working therory? Can we use water to test it?
- The working theory is to detect the micro electricity current between the metals to measure the pH and moisture value.
- There is not any circuit inside.
- Do not test liquid. Otherwise it will damange the meter
