Soil Resistance Meters

Soil Resistance Meters are required for soil resistivity testing with the HM-940 Soil Resistivity Kit to determine the average resistivity of the soil to a depth equal to the spacing between electrodes. The soil resistivity meters are available with analog or digital features and both include a NIST Traceable Certificate of Calibration.

HM-942 Analog Soil Resistance Meter provides soil resistance values to be read directly from the analog dial without performing additional calculations. The wide-range, high-sensitivity soil resistivity meter has a large dial for easy readability, and 8 ranges from 0.1 Ohms to 1.1 Mega-Ohms. It operates on C-cell alkaline batteries. Weatherproof even when the lid is removed.

HM-944 Digital Soil Resistivity Meter selects range and adjusts dials automatically. It features an instant resistance reading at the push of a button, and has a total range from 0.01 Ohms to 10 Mega-Ohms. This model also features data logging capabilities directly to a Bluetooth-enabled PC or Android mobile device (not included) using the included ProCP Soil Resistivity Software. Logged readings can be automatically dated and time-stamped with positioning when integrated with GPS features from the user’s handheld device. Powered by D-cell replaceable alkaline batteries.

The meters are encased in a lightweight, rugged weatherproof IP67-rated plastic.
