Soil resistivity kits determine the soil resistance values. The digital meter and analog meter both determine soil resistance values but with different features. The soil resistance meter features a large dial, with easy readability and eight ranges from 0.1 Ohms to 1.1 Mega-Ohms. As well as displays readings directly from the analog dial of the meter. While the digital meter displays readings instantly with a push of a button. Also provides readings to be logged directly to a user’s Bluetooth-enabled PC or PDA device. The digital meter ranges from 0.01 Ohms to 10 Mega-Ohms.
