3-in-1 Soil Tester Meter for pH Moisture and Light. This 3-in-1 Tester is perfect for testing pH as well as available light and moisture. Moisture readings register on a scale of 0 (dry) to 10 (wet), light readings range from 0 (dark) to 2000 (light), and pH readings between pH 3.5(acidic) and pH 8 (alkaline) are represented. Soil Moisture Tester works by utilizing the electronic ground field effect of the earth and two dissimilar metals. Perfectly use for fruits, flowers, shrubs and vegetables. The Soil pH Meter test the acidity of soil and enable you to alter soil conditions. You can check soil pH at multiple depths.The probe is 8 long for extra large planters. Make you know the moisture of the soil then adjust moisture value to local conditions. Soil Light Meter is suitable for indoors... Less

The AEMC 6472 multi-function digital ground resistance tester with 500 ft. leads performs 2-clamp ground testing (no rod), 2- and 4-wire bond/connection, 3- and 4-point ground, ground coupling, selective ground, soil resistivity, and ground potential testing, and is suitable for use in rugged field conditions. The tester is designed for ease of use with “connect–press–rea d” operation, a large easy-to-read LCD screen, and user alerts. For higher accuracy in electrically noisy environments, the tester can be operated in manual or automatic frequency scan mode from 41 to 513Hz. Test voltage of 16V or 32V can be selected up to 250 milliAmp (mA) test current. The tester automatically recognizes all electrode connections and their resistance value. The auto power-off feature turns off the... Less
